Check Brake Warning Indicator - Ensure brake fluid reservoir is full. Turn ignition on. If warning light is not on, go to next step. If warning light is on, go to step 5).
Check Brake Fluid Level Sensor - Turn ignition off. Unplug connector from brake fluid level sensor. Connect jumper between Purple/White wire at sensor harness connector and ground. Turn ignition on. If warning light turns on, go to next step. If warning light does not turn on, go to step 4).
Check Circuit Continuity - Test Light Green/White and Black wires for continuity between sensor harness connector and ground. Test Light Green/Red wire for continuity between ignition switch, fluid sensor, and parking brake switch. Repair wiring as necessary. If all wires are okay, replace brake fluid level sensor.
Turn ignition off. Remove EIC. See ELECTRONIC INSTRUMENT CLUSTER under REMOVAL & INSTALLATION . Test Purple/White wire for continuity between EIC harness connector terminal No. 25 and brake fluid level sensor. Repair as necessary. If wire is okay, replace EIC, then retest system.
Check Circuit No. 977 - Set shift lever to Park. Release parking brake. Turn ignition off. Unplug connector at brake fluid switch. Turn ignition on. If warning light is not on, go to next step. If warning light is on, repair short on Purple/White wire between EIC harness connector terminal No. 25 and brake fluid level sensor.
Check Circuit No. 162 - Ensure parking brake is released. Turn ignition off. Ensure brake fluid reservoir is full. Ensure Daytime Running Lights (DRL) module is in good condition. Inspect for short on Light Green/Red wire from fluid level sensor. Repair wire as necessary. If wire is okay, replace brake fluid level switch.
