BRAKELIGHT Failure Sensor
- 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 in the SYSTEM WIRING DIAGRAMS article.
- Open trunk. Pull back left inside trunk panel to gain access to brake-light 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 terminal No. 1 (White/Green wire) 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 in the SYSTEM WIRING DIAGRAMS article.
- Turn ignition switch to OFF position. Connect a fused jumper wire between brakelight failure sensor connector terminal No. 2 (Black wire) and ground. Turn ignition switch to ON position 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 EXTERIOR LIGHTS in the SYSTEM WIRING DIAGRAMS article.
