Removal Procedure

    Caution: Refer to SIR Caution in the Preface section.

    Important: In the event of deployment, inspect the supplemental inflatable restraint (SIR) coil for assembly wire for any signs of scorching, melting or other damage due to excessive heat. If there is excessive damage to coil assembly, replace the coil assembly.

  1. Disable the supplemental inflatable restraint (SIR). Refer to SIR Disabling and Enabling .

  2. Object Number: 463032  Size: SH

    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. Remove the mounting bolt hole caps
  4. Loosen the steering wheel inflator module TORX® bolts completely.

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.
