Brake Switch Signal
- Check brakelight operation. If brakelights operate properly, go to step 3. If brakelights stay on continuously, check for continuity between brakelight switch terminals "B" and "C". See Fig 1 or Fig 2 . Repair or replace switch as necessary. If brakelights do not come on when brake pedal is depressed, check fuse located in underhood fuse/relay box. See FUSE IDENTIFICATION table.
- If fuse is okay, repair open circuit in wire between fuse and brakelight switch. See appropriate wiring diagram in WIRING DIAGRAMS article. If wire is okay, check brakelight switch. If fuse in not okay, repair short in wire between fuse and brakelight switch. Replace fuse.
- Depress brake pedal and measure voltage by backprobing between specified PCM terminals. See BRAKE SIGNAL TESTING table. See Figure or Figure. See appropriate wiring diagram in WIRING DIAGRAMS article. If battery voltage exists, brake signal is okay. If battery voltage does not exist, repair open in Green/White or White/Green wire between PCM connector and brake switch.
