Component Tests and General Diagnostics

The anti-lock brake system uses two warning indicators to alert the driver of malfunctions in the system.

The red brake warning indicator will come on for only two reasons:

1. If the brake fluid level in the master cylinder reservoir falls below a certain level.
2. If the parking brake is applied.

The amber CHECK ANTI-LOCK BRAKE warning indicator will come on for numerous reasons. It warns the driver that the ABS and Traction-Assist have been turned off due to a symptom that exists in the system. Normal power-assisted braking remains but the wheels can lock during a panic stop while the indicator is on.

Ensure the diagnostic procedures are followed step-by-step in order as indicated.

CAUTION: Following the wrong sequence or bypassing steps will lead to unnecessary replacement of parts, and/or incorrect resolution of the symptom.
