Lamp Out Sensor: Testing and Inspection
1. First make sure the brake lights come on when the brake pedal is pressed.
^ If all the brake lights come on, go to step 2.
^ It 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.
Brake Light Failure Sensor Test
2. Open the trunk lid, and pull back the left trunk side trim to uncover the failure sensor.
3. Make sure the [BRAKE LAMP] light in the safety indicator does not come on and stay on when the No.1 terminal of the 6P connector is grounded
and the ignition switch is turned from OFF to ON (II).
^ If the [BRAKE LAMP] light comes on and stays on, check for an open in the WHT/GRN wire between the safety indicator and the No. 1
terminal of the failure sensor, and whether the safety indicator circuit (printed circuit board) has a problem.
^ If the [BRAKE LAMP) light does not stay on, go to step 5.
4. Make sure the [BRAKE LAMP] light does not come on when the ignition switch is turned from OFF to ON (II) with the No. 2 terminal of the 6P
connector grounded and the brake pedal pressed.
^ If the [BRAKE LAMP] light comes on and stays on, replace the failure sensor.
^ If the [BRAKE LAMP] does not stay on, check for an open in the BLK wire between the No. 2 terminal of the failure sensor and ground, and
check for poor ground at G502.
