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:

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

    CAUTION: Be careful when you handle a sensing and diagnostic module (SDM). Do not strike or jolt the SDM. Before applying power to the SDM:

       ā€¢ Remove any dirt, grease, etc. from the mounting surface
       ā€¢ Position the SDM horizontally on the mounting surface
       ā€¢ Point the arrow on the SDM toward the front of the vehicle
       ā€¢ Tighten all of the SDM fasteners and SDM bracket fasteners to the specified torque value
    Failure to follow the correct procedure could cause air bag deployment, personal injury, or unnecessary SIR system repairs.

  1. Disable the SIR system. Refer to Disabling the SIR System .
  2. Remove the passenger knee bolster. Refer to Passenger Knee Bolster Replacement in Instrument Panel, Gages, and Console.
  3. Remove the connector position assurance (CPA) from the inflatable restraint I/P module harness connector.

Installation Procedure

    Object Number: 189875 Size: SH
  1. Install the inflatable restraint I/P module (3) to the I/P carrier (1).

    2. 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.

  2. Install the mounting fasteners (2) to the inflatable restraint I/P module.

    3. Tighten
    Tighten the fasteners to 10 NĀ·m (89 lb in).

  3. Connect the inflatable restraint I/P module pigtail connector.
  4. Install the CPA to the inflatable restraint I/P module harness connector.
  5. Install the passenger knee bolster. Refer to Passenger Knee Bolster Replacement in Instrument Panel, Gages, and Console.
