Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Removal Procedure
Refer to SIR CAUTION in Cautions and Notices.
- Disable the SIR system. Refer to Disabling the SIR System .
- Turn ON the ignition.
- Turn the steering wheel 90 degrees so the side of the SIR module is at the 12 o'clock position in order to gain access to the holes behind the steering wheel.
- Insert a screwdriver into the access hole and push the leaf spring to release the notched pin that retains the inflator module.
- Turn the steering wheel 180 degrees in order to gain access to the remaining hole.
- Insert a flat-bladed tool into the remaining access hole and push the leaf spring to release the notched pin that retains the inflator module.
- Tilt the top of the inflator module rearward to gain access to the SIR wiring.
- Disconnect the SIR lead wire from the clip on the inflator module.
- Disconnect the SIR lead wire from the clip on the steering wheel.
- Disconnect the connector position assurance (CPA) retainer from the SIR connector.
- Disconnect the SIR connector.
- Remove the inflator module.
- Fully deploy the module before disposal. If the module was replaced under warranty, fully deploy and dispose of the module after the required retention period. Refer to Inflatable Restraint Module Handling and Scrapping .
When carrying a live inflator module, make sure the bag opening is pointed away from you. This minimizes the chance of injury in the case of an accidental deployment. Never carry the inflator module by the wires. Never carry the inflator module by the connector on the underside of the module.
Make sure that the bag and trim cover are facing up whenever you place a live inflator module on any surface. This is necessary to provide a free space for the bag to expand in the unlikely event of accidental deployment.
Never rest the steering column assembly on the steering wheel with the inflator module face down, and the column vertical. This may result in personal injury.
