Removal Procedure

    Important: If the SIR system deploys, inspect the coil assembly wire for any signs of the following conditions:

       • Scorching
       • Melting
       • Other damage due to excessive heat
            Replace the coil if the coil is damaged.

  1. Disable the SIR system. Refer to Disabling the SIR System in Restraints.

    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.

  2. Disconnect the battery negative cable.
  3. Remove the inflatable restraint steering wheel module. Refer to Inflatable Restraint Steering Wheel Module Replacement .
  4. Remove the knee bolster and IP steering column reinforcement plate. Refer to Driver Knee Bolster Reinforcement Replacement in Instrument Panel, Gauges and Console.

    5. 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.

  5. Install the pinch bolt to the intermediate shaft (5).

    6. Tighten
    Tighten the pinch bolt and nut to 47 N·m (35 lb ft).
