Installation Procedure


    Object Number: 427782  Size: SH
  1. When installing the I/P module (3) do not damage the pigtail and the connector (4).
  2. Route the I/P module pigtail (4) down through the I/P (1).
  3. Install the I/P module (3) to the I/P (1).
  4. 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 mounting fasteners (2) to the inflatable restraint I/P module.
  6. Tighten
    Tighten fasteners to 22 N·m (16 lb ft).


    Object Number: 464929  Size: SH
  7. Route the I/P module wiring harness (2) in place to secure the yellow connector clip to the I/P (3).
  8. Install the I/P upper trim pad. Refer to Instrument Panel Upper Trim Pad Replacement in Instrument Panel, Gages and Console.

  9. Object Number: 464940  Size: SH
  10. Clip the I/P module yellow connector (2) to the I/P bracket (3).
  11. Install the I/P module yellow connector (2) to the vehicle harness yellow connector (1).
  12. Install the CPA (4) to the I/P module connector (2).
  13. Install the right insulator panel. Refer to Instrument Panel Insulator Panel Replacement - Right Side in Instrument Panel, Gages and Console.
  14. Enable the SIR system. Refer to SIR Disabling and Enabling .
  15. Fully deploy the module before disposal. If the module was replaced under warranty, fully deploy and dispose of the module after the required retention period. Refer to Inflator Module Handling and Scrapping .
