Impact Sensor, Front

The front impact severity sensor service requires starting with SRS depowering of the vehicle. Start the front impact severity sensor service by disconnecting its electrical connector that sits at the bottom of the lower radiator support. Both RCM fasteners and impact sensor fasteners need tight installation at specified torques to stop improper restraint operations that carry the risk of severe injury or death during car crashes. Clean both areas where the radiator support meets the sensor while noting the position of the locator tab for correct assembly. Disassemble the front impact severity sensor by removing its securing bolt followed by the sensor unit. The installation of the new sensor requires a bolt torque setting of 12 Nm (9 lb-ft) followed by the reverse steps for removal. The SRS repowering process should finish after checking that the system operates without faults and is ready to release the vehicle to the customer. The diagnostic process should begin again by reattaching the original part if replacing it with a new one does not resolve the problem. Inspect all mounting areas on the restraints control module (RCM) and impact sensors for deformation post-crash before reinstalling original configurations because brand new RCM and sensors will always be needed regardless of air bag deployment.

Before working on the C-pillar side impact sensor the depowering of the SRS system is necessary. The side impact sensor electrical connector needs disconnecting after removing the lower C-pillar trim panel. The procedure for removing the side impact sensor begins with unbolting it then pulling out the sensor from its housing. New sensor installation requires a bolt torque of 12 Nm and ensuring RCM and impact sensor fasteners reach specified torque values to avoid incorrect restraint system operation while tightening to 106 lb-in. Failure to do so can result in life-threatening injuries in a crash. The C-pillar mating surface alongside the side impact sensor should be completely clean along with free of debris before following the uninstallation steps during reinstallation. The vehicle release requires a complete examination and operation check of the SRS system for faults to ensure its full functionality. The RCM and impact sensor mounting locations should receive inspection for any case of deformation after a crash because new RCM and sensors must be installed regardless of air bag deployment status even if the vehicle sustained crash damage.

Beginning any front impact severity sensor service requires disablement of the Supplemental Restraint System (SRS). Remove both the radiator grille after which disconnect the electrical connector from the front impact severity sensor. You must first take out the front impact severity sensor by unbolting it. Use a torque wrench to fasten the new sensor until it reaches 12 Nm torque (106 lb-in). Proper functioning of the restraint system depends on developers to tighten every restraint control module (RCM) and impact sensor fastener to the manufacturer-specified torque value because incorrect operation could result in deadly injuries during accidents. The SRS should be repowered following the reversal of removal steps. The SRS should operate without faults which allows for vehicle delivery to customers. Inspection of the RCM and impact sensor mounting areas should take place for any vehicle involved in a crash and repair should be performed to restore original production specifications for damaged areas. No matter if air bags deployed or not a vehicle needs replacement of RCM along with sensors. The air bag warning indicator will begin to glow if the correct RCM fuse drops out when the ignition switch is ON.

It is secured by two screws.

Failure to do so may result in serious injury or death.

A new RCM and sensors must be installed to prevent serious injury or death in a crash.

The quarter trim panel.

Failure to do so may result in serious injury or death.

Inspect the insert nut for any damage.

Ensure that the fasteners are tightened to the specified torque to prevent incorrect operation of the restraint system.

Reinstall the original part and perform the diagnostic procedure again.
