Chevrolet Captiva Service & Repair Manual: 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. |
