Brake Warning Light

Disconnect electrical connector from brake fluid level warning switch. Release parking brake. Connect a jumper wire between brake fluid level warning switch wiring harness connector terminals (Orange wire and White/Black wire). Turn ignition on. If brake warning light illuminates, circuit and bulb are okay. If brake warning light does not illuminate, check warning light circuit plate. See INSTRUMENT CLUSTER CIRCUIT PLATE .
