For 1990-2009 cars

Under low brake fluid conditions, the low brake fluid switch closes. When closed, the low brake fluid switch grounds (circuit 333, BCM cavity J2-A5). The body control module (BCM) responds by sending a serial data message to the instrument panel cluster (IPC) to turn ON the brake warning light.

### Conditions for Setting the DTC

• | The ignition switch in RUN position.

• | Circuit 333, BCM short to ground or low brake fluid.

• | A 2 second delay to account for slosh.

• | Service (wrench) light will illuminate.

• | The brake light will illuminate with the ignition in RUN.

### Diagnostic Aids

• | Inspect the wiring harness for damage. Check for broken or chafed insulation.

• | If the fault is suspected to be intermittent, wiggling the harness wiring may help in locating fault.

• | Check for poor connection at the BCM. Inspect the harness connectors for backed-out terminals, improper terminal mating, broken connector locks, improperly formed or damaged terminals and poor terminal-to-wire connection (terminal crimped over wire insulation and not conductors).
