Brake Light Failure Sensor Test
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.
• 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 (see page 22-91).
2. Open the trunk lid, and remove the left trunk side
trim (see page 20-78).

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 body ground in the WHT/GRN wire
between the safety indicator and the No. 4
(Sedan) or 2 (Coupe) terminal of the failure
sensor.
• a faulty safety indicator circuit (printed circuit
board) in the gauge assembly.
4. Reconnect the 6P connector. Make sure the BRAKE
LAMP light in the safety indicator comes on and
goes off when the No. 3 (Sedan) or 5 (Coupe)
terminal of the 6P connector is grounded, the brake
pedal is pressed, and the engine is running.
• If the BRAKE LAMP light does not go off, replace
the failure sensor.
• If the BRAKE LAMP light goes off, check for:
- a poor ground (G601).
- an open in the BLK wire.
