Chevrolet Captiva Service & Repair Manual: Anti-Lock Brake System, Inspect

Chevrolet Captiva Service & Repair Manual / Brakes / Anti-Lock Brake System, Inspect

A visual inspection must always be performed to confirm presence of aftermarket components, potential collision damage, or areas of concern.
ABS module is self monitoring. Module will carry out a preliminary electrical inspection of hydraulic pump motor by turning pump ON for approximately 1/2 second either when ignition switch is turned to RUN position and brake pedal is not pressed or when vehicle is in motion and at vehicle speeds above 12 mph. ABS module will also carry out a wheel speed sensor self-test by sending a reference voltage to all wheel speed sensors through their circuitry when ignition switch is turned to RUN position, with or without brake pedal application. If a fault is detected in pump or wheel speed sensors, ABS module will shut down and disable anti-lock system. Normal power assisted braking, however, remains.
1. Verify stop lamps operate correctly by applying and releasing brake pedal with ignition switch in OFF position.
2. Verify that PRNDL operates correctly on instrument cluster.

4. If an obvious cause for an observed or reported concern is found, correct cause if possible before proceeding.
5. Connect a suitably programmed scan tool to vehicle DLC.
6. Carry out network test.
7. Clear continuous DTCs and carry out self-test diagnostics for ABS module.
