Diagnostic System Check

Diagnostic System Check - ABS

Circuit Description
The antilock brake system (ABS) Diagnostic System Check is an organized approach to identify problems associated with the electronic brake control module (EBCM). This check must be the starting point for any EBCM complaint, and will direct you to the next logical step in diagnosing the complaint.

The EBCM is a very reliable component and is not likely the cause of the malfunction. Most system complaints are linked to faulty wiring, connectors, and occasionally to components. Understanding the ABS system and using the tables correctly will reduce diagnostic time and prevent unnecessary parts replacement.
