Lamp Out Sensor: Testing and Inspection
Brake Light Failure Sensor Test1. Check to see if the brake lights come on when the brake pedal is depressed.
- If all the brake lights come on, go to step 2.
- If one of the brake lights does not come on, check whether the bulb is blown. If the bulb is OK, go to step 2.
- If none of the brake lights come on, check the brake light circuit.
2. Open the trunk lid, and remove the left trunk side trim panel.
3. Make sure the BRAKE LAMP light in the safety indicator does not come on and stay on when the 6P connector is disconnected and the engine is running. If the BRAKE LAMP light in the safety indicator comes on and stays on, check for:
- A short to ground in the WHT/GRN wire between the safety indicator and the No. 2 terminal of the failure sensor.
- A faulty safety indicator circuit in the gauge assembly.
4. Reconnect the 6P connector.
5. Make sure the BRAKE LAMP light in the safety indicator comes on and goes off when the No. 5 terminal of the 6P connector is grounded, the brake pedal is depressed, and the ignition switch is turned from OFF to ON (II).
- If the BRAKE LAMP light in the safety indicator comes on and stays on, check for a faulty sensor.
- If the BRAKE LAMP light goes off, check for:
- A poor ground (G601).
- An open in the wire.
