Brake Light Switch: Testing and Inspection

1. Disconnect stop light switch switch connector.
2. Check for switch continuity with an ohmmeter. With brake pedal depressed, there should be continuity between switch terminals. With brake pedal released, there should be no continuity between switch terminals.
3. Reconnect stop light switch connector after testing.

Stop light switch input can be checked at ECU terminal 1J with ignition "ON." With pedal released, terminal voltage should be approximately 0V. With pedal depressed, voltage should be approximately 12V.
