Firebird V6-3.8L VIN K (1995)
Brake Warning Indicator: Description and Operation
Circuit Operation
When the Ignition Switch is turned to "RUN," "BULB TEST" or "START," voltage is applied to the Instrument Cluster through CKT 39 from Gages
Fuse
1. The "BRAKE" Indicator receives a ground through CKT 33 by any one of three components: the Park Brake Switch, Brake Combo Valve,
Electronic Brake Control Module (EBCM) or the Electronic Brake/Traction Control Module (EBTCM).
When the Ignition Switch is turned to "RUN," CKT 33 is grounded through the EBCM or EBTCM, illuminating the "BRAKE" Indicator for
approximately 3 seconds. When the Park Brake is set, the Park Brake Switch closes, grounding CKT 33 through the Park Brake Switch. For a better
understanding of when the Brake Combo Valve, EBCM or the EBTCM will ground CKT 33, refer to Brakes and Traction Control. See: Brakes and
Traction Control
