Inflatable Restraint Steering Wheel Module Replacement



Steering Wheel Inflatable Restraint Module Replacement

Removal Procedure

1. Disable the SDM, refer to SIR Disabling and Enabling (Service and Repair) .
2. Rotate the steering wheel 90 degrees from the straight-ahead position to expose the access aperture hole in the rear of the steering wheel hub.
3. Using tool no. EL-48508 , insert into the aperture and pivot towards the instrument panel moving the tool in an outward direction. This will relieve the tension on the spring-loaded retaining clips. The inflatable restraint assembly will move slightly away from the steering wheel. Rotate the steering wheel 180 degrees to expose the remaining access aperture hole. Repeat for other side.
