2004 Chevrolet Trailblazer Parts Questions & Experts Answers

• Q: How to replace the front air bag sensor on 2004 Chevrolet Trailblazer?

  A: The first step for replacing the inflatable restraint front end sensor involves both sir system deactivation and removal of the grille. Lift the headlamp wire harness from its retaining clip while detaching it to reach the front end sensor. After loosening the frame bolts you must remove the sensor assembly from the frame. The front Bumper should receive the sensor assembly before removing retaining bolts and protective cover from the sensor. Users must eliminate both the connector-position assurance (CPA) from the sensor electrical connector and detach the sensor's electrical connector before extracting the sensor from the vehicle. Before installing the sensor assembly, clean the mounting surface while positioning it flat against the front Bumper. Plug the sensor electrical connector and position the connector-position assurance (CPA) upon the sensor electrical connector. Fasten the retaining bolts together with the protective cover before affixing them to the sensor. Ensure that the sensor assembly remains level with the frame as you direct the sensor arrow toward the vehicle's forward position. Use 8 n.m (71 lb in) torque when tightening the 2 bolts which secure the sensor assembly to its frame position. Place the headlamp wire harness into the retaining clip before locking it into position. Then reinstall the grille and reactivate sir.
