Brake Fluid Level Switch Open Circuit
NOTE:
Perform INSTRUMENT CLUSTER TEST 17A before proceeding with this test. For connector terminal identification and wiring diagrams, see
BODY CONTROL COMPUTER - INTRODUCTION. Perform VERIFICATION TEST: VER-2A after each repair.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
- Disconnect brake fluid level switch connector. Connect jumper between connector terminals. Turn ignition on. If parking brake warning light is illuminated, replace brake fluid level switch. If parking brake warning light is not illuminated, go to next step.
- Disconnect jumper wire. Connect jumper wire between ground and terminal No. 2 (Gray/Black wire) on brake fluid level switch harness connector. If parking brake warning light is illuminated, repair open ground circuit (terminal No. 1, Black wire). If parking brake warning light is not illuminated, go to next step.
- With jumper wire connected, turn ignition off. Disconnect instrument cluster. Using external ohmmeter, measure resistance between ground and terminal No. 3 (Gray/Black wire) on instrument cluster Blue 10-pin connector C2. If resistance is less than 5 ohms, replace instrument cluster. If resistance is 5 ohms or greater, repair open Gray/Black wire.
