Ok doing this procedure correctly will require removal of the steering wheel air bag and air bag module. This can be done without removal of all of this, but you will find it much harder to properly do as you will be basically be working in the dark under the upper steering column trim. If you decide you would rather remove the steering wheel and the air bag, you will need a steering wheel puller. Here is how this procedure is to be done.
Important: The SDM may have more than one fused power input. To ensure there is no unwanted SIR deployment, personal injury, or unnecessary SIR system repairs, remove all fuses supplying power to the SDM. With all SDM fuses removed and the ignition switch in the ON position, the AIR BAG warning indicator illuminates. This is normal operation, and does not indicate a SIR system malfunction.
Important: You must check for 2 pan head tapping screws (1,2) in the lower trim cover before removal.
If screws are not present in the lower trim cover, proceed to the next step.
Important: You must check for 1 TORX® head screw (1) in the upper trim cover (2) before removal.
If a screw is not present, remove the upper trim cover (2).
Push down on the allen wrench to release the tab on the lock cylinder inside the lock cylinder housing.
