AV-SCANNER / Service function guides / Brakes
This guide delivers a complete, professional workflow for diagnosing Antilock Braking System (ABS) module faults, covering pump motor, valve body and electronic control unit failures on passenger vehicles and light trucks. It is written for working mechanics and experienced DIYers who already understand basic brake hydraulics and electrical testing. You will learn how to verify the complaint, interrogate the module with a scan tool, perform pinpoint electrical and hydraulic tests, and confirm a successful repair before the vehicle leaves the bay.
Guidance is general and covers many makes. Exact procedures and values vary by model, so confirm them in the factory service information for your vehicle.
