Anti-Lock Brake System Module - Operation

OPERATION

The ABM voltage source is through the ignition switch in the RUN position. The ABM contains a self check program that illuminates the ABS warning light when a system fault is detected. Faults are stored in a diagnostic program memory and are accessible with the scan tool. ABS faults remain in memory until cleared, or until after the vehicle is started approximately 50 times. Stored faults are not erased if the battery is disconnected.

NOTE: If the ABM is being replaced with a new ABM is must be reprogrammed with the use of a scan tool.
