NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION
. For wiring diagrams, see WIRING DIAGRAMS
. Perform TEST VER-1 after each repair.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting any module connector.
- 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 switch to ON position. 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 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 switch to OFF position. Disconnect instrument cluster Gray connector. Using DRB 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 INSTRUMENT PANEL article in ACCESSORIES/SAFETY EQUIPMENT section.
