The first step required to replace the inflatable restraint side impact sensor is to disable the SIR system. When working with the undeployed inflatable restraint seat belt pretensioner, do not hold it by the wires, or connector; instead, grip it by the piston tube such that the open part is not facing you and others to avoid personal injury. Next, you have to remove the front door trim panel, loosen the 2 inflatable restraint side impact sensor fasteners and remove the inflatable restraint side impact sensor from the door. Drop the connector position assurance (CPA) and yellow 2-way harness connector. For installation, link the yellow 2-way harness connector to the inflatable restraints part-of-impact sensor and link the CPA to the connector. Then connect the inflatable restraint side impact sensor to the door and secure it with the fasteners with the help of hand tools tightening to 10 N.m (89 lb in). Finally, replace the door trim panel, and activate the SIR system.
