Before replacing the inflatable restraint front end discriminating sensor you must disable the sir system while also unplugging the engine protection shield as needed. First disconnect the connector position assurance (CPA) from the sensor harness connector before removing the harness connector from the sensor. The fasteners need removal before removing the sensor from its vehicle location. Use a chisel tool to remove deteriorated weld nuts before installing a new one (GM P/N 11514034 or equivalent) followed by mig weld application. For sensor mounting hole or fastener damages discard damaged parts and condition lower tie front end surface. Reinstall your vehicle with either gm p/n 11515926 or an equivalent fastener. Careful and gentle handling of the new sensor must take place before installation to prevent jarring movements during setup. Prior to mounting clean the surface area completely followed by sensor placement with front-arrow orientation and use 10 n.m (89 lb in) torsion to fasten all screws. Connect the sensor harness in place then install the cpa. Reinstall the engine protection shield while completing an sir system activation.

To replace the inflatable restraint front end discriminating sensor, you have to disable the SIR system first. Lift the vehicle and remove the harness connector attached to the upper part of the frame. Take of the bolts and remove the sensor from the cradle. Clean the mounting surface and fitted the new sensor horizontally to the top of the frame where the arrow inside the sensor points toward the front of the vehicle. Mount the sensor using the mounting fasteners, tighten to be 6.5 N.m (58 lb in). Take out and dispose of the incorrectly installed rivet and re-secure the sensor using a new rivet if the sensor mounting holes or fasteners are damaged. In the case of a second fastener repair, remove the improperly installed rivet, widen the mounting holes in the lower radiator support to 9.0mm (0.35 in), insert and properly seat the rivnut, and tighten the screw to the sensor to the 6.5Nm (58lb in) fastener. Lastly, connect the harness connector to the sensor and crimp it down, lower the vehicle and turn on the SIR system.

Lastly, install the door trim panel and turn the SIR system on.

You must handle the Inflatable Restraint Front End Discriminating Sensor with care while replacement to avoid impact or jarring forces. Make sure to clean your mounting surface before power application while keeping the sensor level with its arrow facing forward. The proper torque value must be applied to all sensor fasteners and brackets to stop both Air Bag deployment and personal injuries. First disable SIR and then raise the vehicle while supporting it from below before removing the Connector Position Assurance (CPA) between the sensor harness and connector. The first step involves disconnecting the harness connector from the sensor followed by removing four mounting fasteners then extracting the sensor out of the front end lower tie bar. Use the first fastener repair protocol which involves stripping a corrupted fastener and nut then chiseling off the damaged weld nut and preparing the surface for the new weld nut before installing GM P/N 11514034 with a mig weld and attaching GM P/N 11515926 sensor tightly to 10 N.m (89 lb in). The second fastener repair method focuses on replacing a defective rivet by expanding the mounting holes to 9.0 mm (0.35 in) while inserting the rivet before tightening it with a screw to 10 N.m (89 lb in). The installation process involves screwing fasteners on the front end lower tie bar to 10 N.m torque and connecting the harness to the sensor before installing the CPA while removing safety stands to activate the SIR system.

In order to replace the inflatable restraint front end discriminating sensor, you would have to disable the SIR system. Lift the vehicle and disconnect the harness connector at the top frame. Take out the bolt and remove the sensor from the cradle. Clean the mounting location; next, install the new sensor horizontally on top of the frame while the arrow in the sensor is aimed towards the front part of the vehicle. Fasten the sensor with the mounting fasteners, tightening them to 6.5 N.m (58 lb in). If the first fastener (rivet) was not correctly installed, remove and trash the fastener, then, reinstall the fastener (introducing a new rivet). If the sensor mounting holes or fasteners have been damaged, remove the improperly inserted rivet, enlarge the mounting holes in the lower radiator support to 9.0mm (0.35 in), insert and properly seat the rivnut, and install the screw to the sensor, and tighten fasteners to 6.5 N.m (58 lb in). Lastly, hook up the harness connector to the sensor, bring the vehicle down, and enable the SIR system.

To replace the side impact sensor, you first need to disable SIR system.
