Caprice V8-265 4.3L VIN W MFI (1995)
Brake Warning Indicator: Description and Operation
Circuit Operation
Voltage is applied to the "BRAKE" Indicator from I/P Fuse #11 when the Ignition Switch is turned to "RUN," "BULB TEST" or "START." The
"BRAKE" Indicator is controlled by any one of three switches: the Brake Pressure Switch, Ignition Switch or Park Brake Indicator Switch.
When the Ignition Switch is turned to "BULB TEST" or "START," CKT 209 is grounded through the Ignition Switch to activate the "BRAKE"
Indicator. When the Brake Pressure Switch is closed, CKT 209 is grounded through the contacts of the Brake Pressure Switch to activate the "BRAKE"
Indicator. CKT 33 is grounded through the Park Brake Switch when the Park Brake is set, to activate the "BRAKE" Indicator.
With the Daytime Running Lamps (DRL) Control Module grounded through CKT 33, the module provides ground to CKT 209, lighting the "BRAKE"
Indicator.
