Disconnect brake fluid level switch connector. Brake fluid level switch connector is located at brake fluid reservoir. Connect jumper wire between brake fluid level switch connector terminals No. 1 (Black wire) and No. 2 (Gray/Black wire). Turn ignition on. If BRAKE warning lamp illuminates, replace brake fluid level switch. If BRAKE warning lamp does not illuminate, disconnect jumper wire. Go to next step.
Connect jumper wire between brake fluid level switch connector terminal No. 2 (Gray/Black wire) and chassis ground. If BRAKE warning lamp illuminates, repair open Black wire. If BRAKE warning lamp does not illuminate, go to next step.
Leave jumper wire connected. Turn ignition off. Disconnect instrument cluster Gray connector. Using scan tool in ohmmeter mode, check resistance of instrument cluster Gray connector terminal No. 6 (Gray/Black wire). If resistance is more than 5 ohms, repair open Gray/Black wire. If resistance is less than 5 ohms, go to next step.
Remove and inspect BRAKE warning lamp. Replace lamp if necessary. If lamp is okay, repair or replace instrument cluster. See appropriate INSTRUMENT PANELS article in ACCESSORIES & EQUIPMENT.
