What is AdvanceTrac?

AdvanceTrac is Ford’s proprietary version of Electronic Stability Control (ESC). It’s similar to what Honda calls VSA and other brands may use different names for their stability control systems.

This system is intended to prevent vehicle skid during extreme circumstances, thereby minimizing the risk of an accident.

Ford’s AdvanceTrac system is relatively complex in nature, and utilizes a series of sensors to monitor wheel speed, as well as various other facets of vehicle stability.

The system actually combines several individual safety systems into a single integrated system, in order to further minimize the chance of a traction-loss induced accident. The following capabilities are possessed by Ford’s AdvanceTrac system.

Anti-Lock Brake Function

Anti-Lock brake systems prevent a vehicle from skidding under panicked braking conditions. When one or more wheels lock under significant brake pressure, this stoppage is communicated to a vehicle’s ABS controller by way of a wheel speed sensor.

This software then commands the system’s ABS pump motor/valve body assembly to rapidly pulsate brake pressure to the affected wheel, thereby breaking the skid.

Traction Control Function

A traction control system compares data from speed sensors at each wheel end location. If the system’s controller detects an irregularity in wheel speed from one wheel to the next, power to any wheel that displays excessive speed will be cut, or brake pressure will be applied.

This effectively evens the speed between each of a vehicle’s four wheels, thereby remedying any prior loss of traction.

Directional Orientated Stability Control Function

Vehicles now rely upon numerous sensors to identify vehicle instability, as skidding occurs. These sensors relay a comprehensive picture of the vehicle’s orientation while in a skid, to a specified controller, which adjusts power output and brake pressure to each wheel as needed for stabilization.

Sources of feedback for this operation include steering wheel angle sensors, yaw rate sensors, and accelerometers.

Why Does the “Service AdvanceTrac” Warning Light Come On?

AdvanceTrac problems

A vehicle’s “Service AdvanceTrac” warning light can be illuminated for a number of reasons, but most often pertains to sensor-related issues. In any event, the system controller has registered a fault, which makes proper operation impossible.

Here are the most common causes of an illuminated “Service AdvanceTrac” warning light.

#1 – Faulty Wheel Speed Sensor

Wheel speed sensors are part of your vehicle’s anti-lock braking system (ABS) and help prevent skidding and tire lock-up by monitoring the rotational speed of each tire.

A damaged or malfunctioning wheel speed sensor can lead to your vehicle’s stability being compromised, triggering the warning light. You may even notice traction loss, particularly on slippery surfaces like ice or snow.

#2 – Faulty Rotational Speed Sensor

Just like the wheel speed sensor, this sensor plays a crucial role in the proper functioning of your vehicle’s ABS system. If this particular sensor malfunctions, it can lead to issues with the ABS module, which controls the ABS system and can result in the AdvanceTrac warning light being triggered.

#3 – Faulty Steering Angle Sensor

steering angle sensor

The steering angle sensor is responsible for measuring the angle at which your steering wheel is turned, and it sends signals to your vehicle’s electronic control unit (ECU) to help maintain stability. If the sensor goes bad, it can affect your vehicle’s ability to maintain stability, resulting in the warning light.

#4 – Compromised Steering System Components

Various parts of the steering system play a vital role in maintaining proper handling and control of your vehicle. If any of these components were to get damaged or worn out, it can impact your vehicle’s stability, resulting in the service AdvanceTrac light coming on.

#5 – Damaged Sensor Wiring

If the wiring harness connecting any of the stability-related sensors becomes loose, disconnected or damaged, it can easily affect the proper functioning of the AdvanceTrac system, resulting in the warning light appearing on your dashboard.

#6 – Broken Clock Spring

A clock spring is the part that’s responsible for maintaining the electrical connection between your vehicle’s steering wheel and the ECU. A damaged clock spring can impact the signals sent from the steering angle sensor to the ECU, causing stability issues.

#7 – Tire or Wheel Mismatch

Mismatched tires or wheels on your vehicle can also lead to the warning light being triggered. This can happen if you have different sized tires or wheels on your vehicle (like a donut spare tire), as it can affect the wheel speed sensors and cause inaccurate readings.

Some Ford vehicles come from the factory with different size tires on each axle and the AdvanceTrac system is configured to take that into account. But if you start running non-OEM sizes all on your own, expect to encounter problems with stability control and other electronic safety systems.

#8 – Low Brake Fluid

Lastly, low brake fluid in your vehicle can trigger the “Service AdvanceTrac” warning light. Low fluid levels can compromise your vehicle’s braking system, and the warning light serves as an alert to check and address this issue. In most cases, you’ll also the brake warning light illuminating.

Can You Continue Driving With the Service AdvanceTrac Light On?

When faced with an AdvanceTrac system issue, you can still drive your vehicle without any ill-effects. However, most vehicles automatically disable all AdvanceTrac related functions, when an active system fault has been detected.

While this is never an ideal situation, you are no more in harm’s way, than when driving a vehicle that is not equipped with a stability control system. 

AdvanceTrac related issues are not detrimental to a vehicle’s driveability, as is often the case when an engine or transmission-based trouble code is stored. In this instance, your vehicle is simply attempting to bring your attention to an underlying fault in its stability system.

However, it is recommended to have your vehicle’s AdvanceTrac system serviced at the first available opportunity, to restore your car’s safety to an optimal level.

In the meantime, it is also imperative to take extra caution when traversing slick or hazardous roadways, such as those encountered following wintry precipitation or heavy snowfall.

How to Reset the Service AdvanceTrac Light

In the case of a “Service AdvanceTrac” light, motorists have little recourse but to fix the root cause behind the light’s illumination.

While it might be tempting to simply clear all pertinent codes in order to disable the system’s warning message, this is nothing more than a quick fix. This light will almost certainly reilluminate with the next cycle of the ignition, as your vehicle performs its standard system self-checks.

In the vast majority of cases, diagnosis of the issue at hand will require the use of a premium scan tool, and a trained eye. However, the avid DIY mechanic can always perform their own visual inspection in an attempt to root out obvious concerns. 

When attempting to locate the root cause of an AdvanceTrac related issue, it is advisable to carefully inspect each wheel’s speed sensor and corresponding wiring harness pigtail. Look for any signs of frayed, pinched, or corroded wires.

Also, check to ensure that all connections between these sensors and their intermediate harnesses are viable. Unplug each speed sensor pigtail from its intermediate harness to check for water intrusion.

In some cases, it might also be possible to check for supply voltage and ground at corresponding modules within the system.

Without full system input voltage, and a stable, resistance-free ground feed, the AdvanceTrac system can experience interruptions in operation. In any event, a vehicle-specific wiring diagram or pin-out reference will be required to conduct such checks.

If you are still unable to locate any obvious source of failure, or simply do not feel comfortable tackling the diagnosis of the AdvanceTrac system yourself, contact a qualified service center for further evaluation.

Preventing Future Problems

wheel speed (ABS) sensor

To prevent future issues with your Service AdvanceTrac warning light, there are a few things you can do to ensure your vehicle’s system runs smoothly.

Monitor and Maintain Wheel Speed Sensors

Stay aware of your wheel speed sensors as they play a crucial role in the functioning of the AdvanceTrac system. Regularly inspect the sensor wiring, clean dirt and debris from the area, and replace damaged sensors when necessary.

Use Correct Sized Wheels and Tires

Make sure your vehicle is equipped with the correct tires and wheels as Ford calls for. Mismatched tires can affect the performance of the AdvanceTrac system, causing it to interpret misleading data.

Be Prepared for Snowy and Icy Conditions

In snowy or icy conditions, the AdvanceTrac system can face difficulties. Maintain a safe driving speed, use appropriate winter tires, and avoid abrupt acceleration or deceleration in these situations. This will lessen the chance of triggering a false warning or experiencing actual performance issues.

Update System Programming

Occasionally, programming issues may cause the Service AdvanceTrac warning light to appear. Stay informed about any software updates or recalls from your vehicle’s manufacturer, and be sure to promptly address these if they arise.

  1. I drive a 2013 Ford Taurus that has previously been in 2 wrecks, both times where the airbags deployed. I got an airbag warning light on for about a week and then my power steering went out and the Service AdvanceTrac light came on. Also my turning lights and brights do not stay on but the windshield wipers work fine. Could it be from a bad steering angle sensor?

    1. Could be a bad steering angle sensor I suppose, but maybe the clock spring? I’m not sure what that would have to do with the power steering cutting out though. It’s also possible that the airbag light is unrelated to the power steering and AdvanceTrac issues.

      Scan the airbag code to see what the cause is. I would be more suspicious that the issues are related if the airbag code refers to a component in the steering wheel.

  2. Good day, sean. I am driving an E350. The Advancetrac warning illuminated yesterday while driving on a freeway. Along with the warning, the three yellow lights mentioned by many above, also lit up. Turning off the key, waiting, then restarting, did not help. Checking for fault codes, using a OBD2 reader, there are no faults shown.

    I recently replaced the battery, thinking that may be the problem, but no help.

    Any ideas?

    1. There may be other codes that your car has stored that do not show up with a basic OBD2 scanner. A more advanced scanner will reveal these.

      A professional scanner will also show you live data from each wheel speed sensor to help narrow down which sensor is acting up. It could also be a problem unrelated to the wheel speed sensors themselves. It’s hard to say without more information.

      If you don’t have access to a scanner like this, you could try lifting the vehicle and checking the sensors and wiring at all four corners to see if one is disconnected or has a wiring issue. Hope this helps.

  3. I have a 2014 Ford Explorer XLT 4WD with a 3.5 engine and 113,000 miles. About a month ago I had very slightly bigger tires put on. About 2 weeks ago, I had many warning lights Brake light, ABS, Check Brake System, Service Advance Trac, Hill Decent Control Fault. In addition, while driving normal and easy, when I got up to 25 – 40 there was shuttering in the engine/ Transmission. My Terrain management system control lights up but does NOT show what mode I am in (Yellow light). I had a electrical diagnostic done. I replaced the MASS Air Flow sensor and Gas Pressure sensor (took 5-7 seconds to start after a gas fill-up). I do need a rear brake job and the brake fluid is full. My only remaining issues are all the Christmas tree of lights about the brakes. I did replaces fuse 27 & 35 relating to the Terrain Management Control even though they were not bad. I also disconnected and re-connected the Terrain Management Control. My thought is the Terrain management control knob is not working which is throwing all the lights and not telling the transmission what is going on causing the shutter from 25-40. I will say the issue between 25-40 is almost gone all by itself. A used Terrain Management control costs about ($165) Lastly, should I clear all the codes now so if I do take it to Ford, the Tech will have the most up to date codes? Thanks for ANY Feedback!!

    1. Did you try putting the original wheel and tire package back on to see if the lights go away? I’m wondering if your wheel speed sensors are having trouble with the new tire size.

      There might be a way to calibrate those sensors. If so, you will probably need a professional grade scan tool to do this. A dealership technician may be able to offer some advice there.

  4. i finally got my firewire setup to read the correct code ,which was p0302

    which is telling me that spark plug #2 has a misfire problem.
    before, all it would show was p0300, a general error

    I changed the spark coil, cleaned the spark plug and it started running real nice, again.

  5. 2015 f350 Check Advance Trak comes in and the engine shifts to 4 low, out has been to a dealer several times fixing this and that but the issue still occurs. What is going on that Ford can’t determine what is wrong?? I’m worried it might cause an accident. No other warning lights…

  6. I have the same issue as Paul, above

    all of a sudden, going down the road, the ‘check engine’ light comes on and it starts cutting out, and sputters at lights and signs.
    Once you get up to speed, it semi corrects itself, but, just wait for the next light…..bummer..

    i had to park it as it is, ,like Paul says, very dangerous to drive.

    Ford should know about this issue and have a fix for it.
    Just because something in the drive train doesn’t like spinning, it should never affect vehicle performance.


    what is limp mode.

    shouldn’t it be explained if it is mentioned and what causes and fixes it?

  7. I have 2015 Ford Fusion. Had an accident where another driver hit into the front passenger side of car. Tire was replaced and new brakes installed. When picking up car from repair shop the abs light, service advance trac and advance trac off on lights were on. I have been told by repair shop they tried a new sensor and light came back on so has to be a dealer issue. Told Ford had a recall to fix this. Now being told it is a wire that needs repaired. Had another shop run scan which shows right front sensor bad. These lights were not on before accident. Ford dealer doesn’t know when they can give an appointment. Can the accident caused all this? I need someone to be honest and repair.

    1. Yes, an accident can cause all sorts of damage that can be hard to find and fix. Imagine just the wrong wire getting pinched, causing a short, and then giving you electrical problems. This could happen in an area of the car that doesn’t typically see wear related to weather and road debris. I think it’s odd the body shop wouldn’t take a look at that issue, though. Sounds a bit like a job half done.

  8. Just replaced the battery as it was completely dead (5th battery BTW) on my 2014 Explorer and now the brake system and AdvanceTrac lights are on. Suggestions?

    1. I’m not sure the brake and AdvanceTrac lights are related to replacing the battery. I would do a diagnosis of those systems, guessing that perhaps there is an issue with a wheel speed sensor or the ABS system.

  9. We have a Ford Expedition EL 2010, My hub went out on the front driver side which caused my ABS and Service AdvanceTrac to come on. My husband’s a mechanic so it wasn’t a big deal to fix what went wrong. My question is does he need a scan tool to clear the codes.

    1. I don’t think he will need a scan tool if he ends up doing the work on his own. If I’m wrong, you should be able to get those codes cleared at an auto parts store. They have scan tools available.

  10. Thanks Sean.
    I have a 2017 Navigator. The ABS, Advanctrac and traction control lights came on today. No obvious performance issues.
    Are the speed sensors inside the hub assembly? I just replaced both front hub assemblies 2 weeks ago.

  11. That issue is because a wire from the power steering to the battery is loose. look for any messed-up wires under there.

  12. I just got the A-trac, hill assist, drive mode issue after swapping my spare for my rear passenger tire on my 2018 F150 STX. I threw the original in the bed and drove it to the shop to fix the flat during my lunch break. Came back to the office and continued home afterwards. Almost as soon as I drove off the parking lot the error message came up. It like it knew the tire was missing. A few miles down the road, the tps warning came on. The next day the tps showed the missing sensor and the A-trac fault went away. Second day the tps came back on, still with only the spare, and after leaving my office the ATrac came back. There seems to be connection between the TPS sensors and the A-trac system. After putting my original tire back on, all is good again.

    1. Some vehicles have TPMS sensors in the wheels. Other systems use the wheel speed sensors to determine if a tire is flat. You’ll have to check which type of system your F-150 uses, but some are more sensitive to change than others.

      TPMS sensors in the wheels can be recalibrated by a special tool that most tire shops have. If your truck uses the wheel speed sensors instead, you may have a button on the inside of the cabin that you can hold to reset the tire pressure monitors. The button should look like the icon on the tire pressure warning light.

  13. I have 2016 F-150 4WD. When my advance trac warning comes on I lose throttle input from idle or a stop. It creates a dangerous situation as I cannot accelerate when pulling out into traffic or turning from a stop or red light. I end up rolling through an intersection at very low speed and it takes time to eventual get up to speed. Once cruising throttle response is ok and I can accelerate. The dealer could not get it to reliable replicate but did find fault with the pedal assembly. Made sense so I had it replaced. Didn’t get a half mile from the dealer and it happened again. First the article states you can drive with no ill effects. My situation is quite dangerous. Any guidance where to try next. The deal is on the path of changing parts.

    1. Much of the time the Service AdvanceTrac light is on because of a bad wheel speed sensor or something similar. In a case like that, you usually can drive without too much of an issue, you just might not have ABS or traction control.

      Your situation sounds different. If there is a problem with the pedal assembly, it may not be detecting throttle input correctly. That could explain why you can’t pull away quickly from a stop.

      I could see a bad pedal assembly triggering a Service AdvanceTrac light, although it is a very different issue than the original article had in mind; I would expect another warning light to be on at the same time, or perhaps the vehicle would even enter limp mode. The factory service manual should have a detailed description of all the failures that could potentially trigger this warning light.

      My next step would be a thorough electrical diagnosis. Check every single sensor (and wiring) that the AdvanceTrac system reads data from. To do this, you will need a factory service manual from Ford. You should be able to find one online. Electrical diagnostics can be a difficult and time consuming process, but it can save you a lot of money when the alternative is the parts cannon.

      1. Our 2019 Explorer just had this Advance Trac notice on dash display. Drove immediately to dealership and codes indicated Mass Airflow sensor bad. Sensor replace and so far so good.

  14. My wife has a 2013 f 150 Ecoboost. The Advance trac light will come on and then it will not have any turn signals or 4 way flashers. Took it to a Ford Dealer to have it fixed they said that the steering column module was bad. She said order part and fix it 3 weeks later the part came in dealer installed it, everything worked no advance trac light then about 10 days later the light came on again and no turn signals again you can stop turn the truck off restart it and everything works again as it should. then again for no reason it will come on again. Also when the advance trac light is on so it shows the traction control light is on. The dealer has had it for three days now and say then can not find any reason for it to keep coming on. Give me your best guess as what might be the cause for the light coming on. Thanks

  15. I have a 2013 Ford Edge. My Service Advance Trac light comes on as well as the traction control light that says off and the car sliding light comes on too. Then the light to indicate what gear you are in ( P, R, N, D, S) all go off. If you shift the vehicle, a big thud happens and sounds like the transmission is falling out of the vehicle. If you shift it from Park to Drive or Reverse a few times, it will finally go. Took it to Ford and they did a system update. Happened again a week later. Sometimes it happens everyday and sometimes it might go 2 to 3 weeks before it happens again. Today it happened right when I started the vehicle. Haven’t even moved. Most of the time it happens when you put it into park. Also did it when I drove to the end of the street. Haven’t heard anyone say anything about the thud when shifting from the transmission with these lights on. Getting frustrated with it. Any help would be greatly appreciated.

    1. Forgot to add, 2 days ago I just had a works service done at Ford, so all fluids were checked and oil changed.

    2. Sounds like it may be an issue with the transmission, but I’m not sure. This is the type of issue I think would be wise to pay for a diagnostic from a good shop. Getting the diagnosis wrong on this could cost a bunch of money replacing perfectly good parts.

  16. My AdvacneTrac warning light came on along with my Park Brake light (same time) when I had to slam on the brakes from hitting a lady who pulled out in front of me (just missed her my speed was 65 on the freeway I barley missed her. I have a 2011 Lincoln Navigator. Could it be just the “box” that needs to be replaced? Looking to do this as cheap as possible. Any ideas would be helpful.

    1. I don’t know. Check your brake fluid level to make sure you still have plenty of brake fluid. If it were me, I would not cheap out on brake issues. Take it to a shop and have them check it out to make sure it’s safe. The park brake light often comes on just before braking system failures, and often the kind that leave you without any brakes at all.

  17. 2011 F150 Planuim. Advance Track light came on and the power steering emediatly stopped working causing a manuel hard non assisted fight to steer the truck. Any idea why?

    1. Not sure. I would hook up a scanner to see why the AdvanceTrac light came on. It may show you one or more sensors have failed to operate correctly.

    2. Did you figure out the issue. I’m asking bc I have the exact same name and model as you and this just happened to me about 5 minutes ago. Thanks in advance for any reply.

  18. Same thing happened to my 2010 Ford Fusion Hybrid on December 2, 2021. Dashboard displayed the warnings: Check brake system, service advance track, and ABS turned off. The brakes were not working normally and it took a lot longer to stop.
    Had to drive really slow to get home from work. The next morning everything was working so I drove straight to my trusty mechanic. They said I have to take it to the Ford Dealer based on the error codes. I had the same thing fixed a couple of years ago by my mechanic, but I guess since it came back will have to pay the dealer.

  19. 2015 Ford Fusion Hybrid – Service AdvanceTrac came on a couple of months ago and i stopped and turned off the car and back on and everything was fine but the check engine light was on but the car ran fine. then every once in awhile very inconsistently as im driving and the engine goes from driving in electric to right when it switches to the gas engine Service AdvancTrac comes on again and i have to turn the car off again and back on and everything is fine again. It seems to only happen right when its switching from electric to gas that it happens but it doesn’t happen every time just some times. Im so confused, iv searched the internet for anyone with a similar issue and i get a lot of the Service AdvanceTrac issue but nothing like mine.

    1. Also if i keep driving without turning the car off and drive while the Service AdvancTrac warning is on its only drives while on the electric battery and if i drive long enough and i run the electric battery down i can go any faster than 15 MPH and even on a full battery i dont get past 40MPH

      1. I am not sure what the issue is. I think this is something that would be best handled at a local shop, where they can hook up a scan tool and determine which sensor(s) are the root cause of the problem.

  20. I have a 2012 Ford Fusion SE that had a flat tire and caused the power steering to go out. Even though there is a recall on this model for the power steering, the dealership told me it wasn’t due to the recall and was gong to cost with everything fixed $4,000.
    I decided to drive the car without power steering for a year and took it to pep boys to get a new tire. I don’t know what they did, but the power steering has been working fine for a couple of years now. They never mentioned anything.
    About 6 months later my stereo speakers started popping whenever I would hit any kind of small bump in the road. So no stereo and no speakers for almost 9 months. Whenever they do come on, the sound is great but it doesn’t stay on long. The steering wheel lights no longer work nor the gear shift lights.
    Recently, I had another flat. I took the car to Walmart to get a new tire put on. Now the dashboard lights say a car door is open (they are all closed) and it beeps and flashes service breaks and service advance track.
    The breaks could def be replaced but they don’t show any sign of being worn out. I just have to push them a little harder than my other car. I don’t know what advance track is, but it always was on when I had no power steering.
    Last night I changed 2 fuses. Number 38 and 39 for the radio and subwoofer/amp and to my complete shock the stereo is working great, the speakers are not popping and not going out when I hit a bump.
    My question is, could all of this other stuff be fixed by simply changing a fuse?

    1. AdvanceTrac is Ford’s stability control system. Why did the dealer tell you the recall didn’t apply to your vehicle?

      It sounds like you have several unrelated issues going on. If those fuses blow again, I would pay for an electrical diagnosis from a qualified technician to help you narrow down the problem. I suspect you may have a short or a bad ground somewhere in the electrical system. The power steering may or may not be related. I believe that is an electric power steering rack so it’s possible.

      Good luck on your search, and don’t just replace the fuses if they blow again; make sure you get an accurate diagnosis of the problem. Fuses are there for safety to keep the car from catching on fire, so you’ll need to find the root cause before this can be resolved for good.

  21. Hi Sean,
    Is the Service AdvancedTrc diagnostics and repair normally covered under an extended warranty by Ford?

  22. most likely its the big circut fuse on the positive battery terminal , it has 2 computer harness leads going to it held on by 2 10 mm nuts,,,,,,and 1 14mm bolt holding the big fuse on the terminal…remove and replace, problem solved

  23. the service advancedtrack light on my ford f150 2012 fx2 came on after I installed a 2-inch level kit on the front side of my truck… what solution is needed to avoid further problems?

  24. My 2018 F150 had the same track lock problem with my Power steering drive mode and many others. Found issue two ground wires under the hood driver side fender well actually behind my airbox . It’s a bad connection And over torqued which cracks The connector. Install new Connector everythings fixed .

  25. What a crock of garbage. 1 year old car and it shuts down. I’m already sick of all the other automated junk that doesn’t work on this car. Now my wife cant drive her car safely. Way to go ford!

  26. I have a 2011 Lincoln MKX and after changing to new battery I have service advancetrac light on now. I had a tire with low pressure also but after adding Air the pressure illumination light went away.

  27. I have a 2014 f-150 and today for the first time I have three warning lights come on at the same time. The ABS, the check brake system and the service advancetrac. Never had the slightest issue before.

    Checked the brake fluid level as I just had the oil changed and it was fine.

    Checked for leaking brake fluid–no issues there.

    What next????

    1. Sounds like a bad wheel speed sensor, maybe. The best thing to do is use a scanner to check the output of each wheel speed sensor. If one isn’t registering, that’s the problem wheel. Then you can use that data to determine if the sensor itself is wrong or if there is some other mechanical or electrical issue elsewhere in the system.

        1. service advance light is on I recently had a low tire pressure and I got the flat fixed and now the service advance light is on. What do I do

        2. You could try disconnecting the negative terminal on the battery for about 10 seconds, reconnecting the battery, and seeing if the light comes back. If the light comes back, you should take the vehicle to the shop that fixed the flat and tell them about the problem.

          Be aware that when you disconnect the battery certain saved values such as your trip meter may be cleared.

      1. Sean, Ive had the same issue with my 2012 flex the TPS tire low pressure light, followed by advance track and door ajar light flashes as well short after that all ACCESSORIES shut off but engine stays running for a sec then everything that was on comes back as normal. Any thoughts?

        1. Please check your tire pressures. Aside from that, I’m wondering if there is an electrical issue like a bad ground that is triggering all those lights at the same time. Check that all grounds are clean and tight, including the main ground at the negative battery terminal.

  28. Hi, I’ve had the same issue with my 2010 Fusion Hybrid. Let the car sit with no driving during the pandemic and one tire went flat for an extended period (probably was sitting on the rim) and the battery died.
    Took it into the dealership and they diagnosed a complete replacement of the powersteering ($2200). I’ve read several forums like this and the “flat tire and/or dead battery” seems to be thematic precursor to the power steering going out and “service advancetrac now”. It seems like some people get the dealer to ‘reset the code’ and that is successful. (sometimes only temporarily). Others seem to reset codes + install a new battery to have permanent success.
    Anyone else find a solution? Or specific direction to give the dealer to make sure one can ask “Did you reset code YYYYY? I’ve read this works to restore the power steering.”

  29. On April 14, 2021 the dashboard of my 2010 Ford Fusion Hybrid displayed the warnings: Check brake system, service advance track, and ABS turned off. The brakes were not reacting normally to the point that it took a lot longer to stop. The brakes felt spongy.

    On 2/14/2021 we had the same thing happening. We then thought that the 12-volt battery needed to be replaced. So we did replace it and up to April 14, 2021 there were no more problems.

    So here we are again. I don’t trust this car anymore because at any time this can happen again with some bad consequences possible. I have barely 84,000 miles on it.

    We are going to have it diagnosed by a Ford dealer but I will like some insight into this very serious safety problem.

    1. Good, a professional diagnosis is needed. It sounds like there’s definitely something wrong with the braking system, but I’m not sure if it’s as simple as air in the lines or if there is a problem with a module. Did you check the brake fluid reservoir? Any fluid missing?

      A wild guess is perhaps there is a leaking brake line and there is air in the ABS system. I’d be interested to hear back after you get the issue diagnosed by a technician at the dealership, though.

      1. We recently bought a 2013 f150 3.7L with only 128xxx from an elderly man.
        When we took it to the garage to be saftied for the road, we were told the upper ball joint needed to be replaced. (Control arm is attached to that piece as well) and since changing the control arm, the service advancetrac light is on, I am wondering if maybe there was a wire pulled loose? Or a sensor malfunctioning. If you could give me any tips that would be great as we plan on driving half was across Canada in 4 days and this knight just showed up out of no where. We have a code reader, and are going to use that to see if it’ll give us any further info. But if anyone knows of anything that would help out it would be significant, thanks!

        1. Yeah, there’s a chance something is up with the wheel speed sensor on that corner. I would take it back to the shop that replaced the ball joint and have them check it over. It could be as simple as forgetting to plug that sensor back in.

  30. My service advance Trac light came on for a few minutes in my 2010 Mercury Milan. Do I need to get it checked out? Can it be replaced/repaired? If yes how much will it cost?

    1. I would get it checked out, yes. The code will still be stored so the mechanic should be able to see what happened even if the light isn’t currently displayed on the dash.

      It can probably be replaced or repaired. It’s hard to say how much it will cost until you know exactly what the problem is. You may have to pay a small diagnostic fee for the mechanic to solve the problem, but this charge for their time is more than worth it.
