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 EXTERIOR LIGHTS article.
- Open trunk. Remove taillight access panel from left taillight. Access brakelight failure sensor. Turn ignition switch to OFF position. 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 switch to ON position. 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 EXTERIOR LIGHTS article.
- Turn ignition switch to OFF position. Connect a fused jumper wire between brakelight failure sensor connector Black wire terminal and ground. Turn ignition switch to ON position and depress brake pedal. BRAKE LAMP indicator should not illuminate. If BRAKE LAMP 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 EXTERIOR LIGHTS article.
