    2.  
    3. Remove the SIR fuse from the Instrument Panel Junction Block (IPJB).
    4.  
    5. Remove the Connector Position Assurance (CPA) device, then detach the yellow 2-way SIR connector at the base of the steering column.
    6.

  3. If equipped with a passenger side air bag, perform the same SIR system disabling procedure with the addition of the following steps:
    1. Using a small, flat bladed screwdriver, pry off the upper instrument panel pad screw caps. Remove the trim panel retaining screws.
    2.  
    3. Disengage the rear trim panel clips by lifting up. Then, disengage the front trim panel clips by lifting up at each outer corner and pulling rearward. Be careful not to damage the trim panel during its removal from the vehicle.
    4.  
    5. Remove the upper trim panel insulator.
