Component Tests and General Diagnostics

The Bendix Anti-Lock 10 Brake System has self diagnosis capability. The self diagnosis cycle begins when the ignition switch is in the ON position. An electrical check is completed on the ABS components such as wheel speed sensors continuity, system continuity and other relay continuity. During this check the Anti-Lock Light will be on for approximately one to two seconds.

The ABS system is constantly monitored by the CAB. If the CAB detects a fault, it can disable the brake system anti-lock function. Depending on the fault the CAB will light either one or both brake system warning lamps.

The CAB contains a Self-Diagnostic Program which activates the indicator lights when a system fault is detected. Faults are stored in a diagnostic program memory. There are 19 fault (trouble) codes which may be stored in the CAB. These fault codes will remain in the memory even after the ignition switch is turned off. The DRB II tester must be used to access diagnostic fault (trouble) codes.

When diagnosing and testing system refer to Diagrams/Electrical for wiring diagrams terminal identification, and Diagnostic Charts for diagnosing fault (trouble) codes.

This ABS system has a self diagnostic connector located under the lefthand side of the instrument panel, left of the steering column. The diagnostic connector is a blue 6-way connector which can be connected to a DRB II readout box.

When diagnostic procedure is complete refer to ABS system diagnostic verification test.
