The “Service Advancetrac” error message indicates a problem with the traction control system.
It could also be caused by a bad battery, bad ABS sensor, low brake fluid level, throttle body malfunction, or a bad steering rack.
In the next parts, how to solve the Ford F150 Service Advancetrac error message will be discussed.

How to Fix Ford F150 Service Advancetrac?
Ford F150 Service Advancetrac error message usually means a problem with the traction control. But it can also be a battery problem, brake system issue, steering issue or a throttle body malfunction.
Reason 1: Weak Battery
One of the reasons for the “Service Advancetrac” message could be a weak battery. You need to check your battery for corrosion and its voltage to ensure the health of your battery.
Remove the negative terminal first, then the positive terminals to check them for corrosion. If the terminals are corroded, clean them with baking soda and water.
If not, then check the battery voltage with a multimeter. If the voltage is close to 12.6 with the car turned off, then it’s healthy. If the voltage is around 11 volts, that means it’s low on charge. If the battery voltage is below 10 volts, it means the battery is faulty.
If the battery has low voltage, recharge it. Replace the battery if it’s faulty.
Reason 2: ABS Sensor Malfunction
A bad ABS sensor can make the “Service Advancetrac” error message appear on your Ford F150. Along with that, you will see your ABS light turned on.
In that case, you must check if the ABS sensor works. To check the sensor, locate and remove it from the harness.
Then connect it to a multimeter using alligator clips. Set the multimeter to read in the 20 kOhm range.
Now, the meter should give you a reading between 800-2000 ohms. If the reading is not within this range, the ABS sensor is malfunctioning. In that event, you will have to replace the ABS sensor.
Reason 3: Brake Fluid Too Low
The traction control and the brake system both use brake fluid. So, when the brake fluid is too low, it can trigger the “Service Advancetrac” and “Check Brake System” lights.
Check the brake fluid level in your vehicle. The brake fluid reservoir is usually located behind the driver’s side engine bay.
If the fluid level is low, add the recommended type of brake fluid to bring it to the proper level.
Reason 4: Throttle Body Malfunction
If your Ford F150 is displaying a “Service Advanctrac” message and not starting, the throttle body of your car is malfunctioning.
Also, sometimes the “Hill Descent Control” warning message can also pop up.

Since the throttle body might have a malfunction, you need to have it checked.
However, this can be a very challenging task because of the location of the throttle body. It’s best to contact a mechanic for a throttle body diagnosis and replacement.
Still, if you insist on doing the tasks yourself, here is a video guide-
Reason 5: Bad Steering Rack
If you have a bad steering rack in your Ford F150, it can trigger the “Service AdvanceTrac” message on your dashboard. That’s because the traction control system is dependent on it for information.
This solution involves checking the steering rack and replacing it if it’s faulty. The diagnosis and replacement process is highly difficult and takes more than 6 hours. So, it’s best to rely upon an expert.
