If you are experiencing issues with the ABS and traction control lights coming on after disconnecting or replacing the battery in your vehicle, there is a simple procedure you can follow to reset them.
When you start the vehicle, turn the steering wheel all the way to the left and then all the way to the right, repeating this motion twice. Afterward, drive for about two minutes, and this should reset the traction control and ABS warning lights.
The reason behind this method is that disconnecting the battery can cause the ABS module to lose track of the steering wheel’s position, impacting its ability to calculate braking and the ABS function. By turning the wheel as described, you provide the necessary input for the system to recalibrate.
It’s important to note that while this method can resolve the issue in some cases, it may not work if there are underlying component malfunctions such as a faulty ABS wheel speed sensor, ABS module, or steering angle sensor. If the reset procedure does not work, it is advisable to read the fault codes to accurately diagnose the problem.

How can I reset the ABS and traction control lights?
To reset the ABS and traction control lights after disconnecting or replacing the battery, start the vehicle and turn the steering wheel all the way to the left and then all the way to the right, repeating this motion twice. Then, drive for about two minutes to reset the lights. This process is effective because disconnecting the battery can cause the ABS module to lose the steering wheel position information it needs to calculate braking and anti-lock brake function.
Why might the resetting process not work?
The resetting process may not work if there is a problem with the ABS wheel speed sensor, the ABS module, or the steering angle sensor. In such cases, it’s necessary to read the fault codes to determine the specific issue with the vehicle.
