Brake Light Switch: Testing and Inspection

Brake Switch Test





1. If the brake lights do not go on, check the No. 25 (20 A) fuse in the under-hood fuse/relay box, and the brake light bulbs in the taillights assembly and the high mount brake light.
2. If the fuse and bulbs are OK, disconnect the 2-P or 4-P connector from the brake switch.
3. Check for continuity between the B and C terminals. There should be continuity with the brake pedal pushed.
^ If there is no continuity, replace the switch or adjust pedal height.
^ If there is continuity, but the brake lights do not go on, check for:
- Poor ground (G701: Coupe/Sedan), (G602, G604, G605: Wagon).
- An open in the wire.
- Faulty brake light failure sensors.
