Removal Procedure

    Caution: This vehicle is equipped with a Supplemental Inflatable Restraint (SIR) System. Failure to follow the correct procedure could cause the following conditions:

       • Air bag deployment
       • Personal injury
       • Unnecessary SIR system repairs
    In order to avoid the above conditions, observe the following guidelines:
       • Refer to SIR Component Views in order to determine if you are performing service on or near the SIR components or the SIR wiring.
       • If you are performing service on or near the SIR components or the SIR wiring, disable the SIR system. Refer to Disabling the SIR System.

  1. Disable the supplemental inflatable restraint (SIR). Refer to Disabling the SIR System in SIR.
  2. Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

  3. Disconnect the negative battery cable.

  4. Object Number: 443915  Size: SH
  5. Remove the 2 TORX® head screws from the back of the steering wheel.
  6. Remove the connector position assurance (CPA) clip (2) and the electrical connection (3) from the rear of the inflator module (1).
  7. 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.

  8. Remove the inflator module (1) from the steering wheel.

Installation Procedure

For the SIR Steering Wheel and Components refer to Steering Wheel and Column Description .


    Object Number: 443915  Size: SH
  1. Install the connector position assurance (CPA) clip (2) and the electrical connection (3) to the rear of the inflator module (1).
  2. Install the inflator module (1) to the steering wheel.
  3. Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

  4. Install the 2 TORX® head screws to the rear of the steering wheel.
  5. Tighten
    Tighten the inflator module-to-steering wheel screws to 10 N·m (89 lb in).

  6. Connect the negative battery cable.
  7. Enable the SIR. Refer to Enabling the SIR System in SIR.
