General Description

The red BRAKE warning lamp in the instrument panel cluster (IPC) illuminates to alert the driver to either a brake system condition which reduces braking ability or a park brake which is not fully released. Specific conditions which cause the BRAKE warning lamp to illuminate include the following:
1. Park brake not fully released. When the parking brake is applied or not fully released, the switch on the parking brake pedal assembly grounds the BRAKE warning lamp, causing it to illuminate.
2. Low brake fluid. The fluid level sensor in the master cylinder reservoir grounds the BRAKE warning lamp when low brake fluid is detected.
3. Ignition switch BULB TEST position. The ignition switch also grounds the BRAKE warning lamp when the ignition is moved to the BULB TEST or START position. This condition will last for approximately 2-4 seconds when the ignition switch is turned to the RUN position.
