GM Service Manual Online
For 1990-2009 cars only

This brake system uses a BRAKE warning lamp in the instrument panel cluster. When the ignition switch is in the START position, the BRAKE warning lamp should glow and go OFF when the ignition switch returns to the START position.

The following conditions will active the BRAKE warning lamp:

    • Parking brake applied. The light should be ON whenever the parking brake is applied and the ignition switch is in the ON position.
    • Low fluid level. A low fluid in the master cylinder will turn the BRAKE lamp ON.
    •  DDRP system is disabled. The light should be ON when the DDRP system is malfunctioning.
