  Q: How to service and repair the Air Bag Sensor Front End Discriminating SEN on GMC Envoy?

  A:

  Begin repairs on the inflatable restraint front end discriminating sen by disabling the sir system first. To access the front end discriminating sensor vehicle owners must first remove the grille then detach the headlamp wire harness from its retaining clip before raising it for sensor inspection. You should release the bolts which secure the sensor to the frame and then extract the sensor assembly. Start by placing the sensor assembly in position above the front Bumper. After that extract the retaining bolts and protective cover from the sensor. The connector position assurance (CPA) and sensor electrical connector need to be liberated before extracting the sensor out of the vehicle. Installation begins by placing the sensor assembly above the front Bumper then connecting the electrical connector before placing the cpa onto the electrical connector. Install the retaining bolts and protective cover to the sensor before placing the sensor assembly against the frame. Fasten the 2 bolts with 8 n.m torque (71 lb in). Once the retaining clip is secure, install the grille by repositioning the headlamp wire harness. Finally, enable the sir system.
