Steering Wheel Inflatable Restraint Module Replacement for Chevrolet Blazer - 4WD - RHD 2000

Caution: When performing service on or around the SIR components or the SIR wiring, follow the procedures listed below in order to temporarily disable the SIR system. Failure to follow the procedures could result in the following:

•	Air bag deployment

•	Personal injury

•	Otherwise unneeded SIR system repairs

1. Disable the SIR system. Refer to Disabling the SIR System .
2. Turn the ignition switch to the ON position in order to unlock the steering wheel.
3. 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 access holes behind the steering wheel.



4. Insert a flat-bladed tool into each access hole and push the leaf spring in order to release the notched pin that retains the inflator module.



5. Turn the steering wheel 180 degrees in order to gain access to the remaining access holes.
6. Insert a flat-bladed tool into the remaining access holes and push the leaf spring to release the notched pin that retains the inflator module.



7. Tilt the top of the inflator module rearward in order to gain access to the SIR wiring.
8. Disconnect the SIR lead wire from the clip on the inflator module.
9. Disconnect the SIR lead wire from the clip on the steering wheel.



10. Disconnect the connector position assurance (CPA) retainer.
11. Disconnect the electrical connector.

Caution: 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.
12. Remove the inflator module from the vehicle.
13. 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 Inflator Module Handling, Shipping, and Scrapping .
