Brake Light Switch: Testing and Inspection
Stop Light Switch Testing
1. Disconnect switch connector.
2. Check switch continuity. With brake pedal depressed, there should be continuity between terminals. With brake pedal released, there should be no
continuity between terminals.
3. Replace switch if it does not perform as specified.
Stop light switch input can be checked at PCME terminal 1Q, ignition ON. With pedal released, terminal voltage should be below 1.0V. With pedal
depressed, voltage should be approximately 12V.
