BRAKELIGHT Failure Sensor Test
- Ensure brakelights illuminate when brake pedal is depressed. If one bulb does not illuminate, check bulb condition. Repair as necessary and recheck. If all brakelights illuminate, go to next step. If no brakelights illuminate, check brakelight system. See Figure and Figure .
- Open trunk. Remove taillight access panel from left taillight. Access brakelight failure sensor. Turn ignition off. Disconnect brakelight failure sensor 6-pin connector. Connect a fused jumper wire between brakelight failure sensor 6-pin connector White/Green wire terminal and ground. Turn ignition on. BRAKE LAMP indicator should not illuminate. If BRAKE LAMP indicator illuminates and goes out, go to next step. If BRAKE LAMP indicator illuminates and does not go out, check for an open in White/Green wire between safety indicator and brakelight failure sensor. See Figure and Figure .
- Turn ignition off. Connect a fused jumper wire between brakelight failure sensor connector Black wire terminal and ground. Turn ignition on and depress brake pedal. BRAKE LAMP indicator should not illuminate. If BRAKE LAMP indicator illuminates and does not go out, replace failure sensor. If BRAKE LAMP indicator illuminates and goes out, check for an open in Black wire between safety indicator and ground connection. See Figure and Figure .
