ABS light on after changing brakes. How do I reset the system to turn the ABS light off? Sensors are connected and no fault codes! Light has been on for two months since replacing brakes.

Hello,

It sounds like the new rotors do not have the ABS wheel reluctor on them. Did you match the rotors up?

Here is a guide to help you test the BAS wheel speed sensors to confirm the problem.

Please let us know what happens.

Cheers, Ken

You will need to scan the vehicle to determine the Diagnostic Trouble Code (DTC) for the ABS system.

Begin your diagnosis there.
