When performing service on or around the SIR components or the SIR wiring, follow the procedures listed below in order to temporarily disable the SIR system. Failure to follow the procedures could result in the following:

  • Air bag deployment

  • Otherwise unneeded SIR system repairs
  1. Disable the SIR system. Refer to DISABLING SYSTEM in SIR.
  2. Turn the ignition switch to the ON position to unlock the steering wheel.
  3. Turn the steering wheel 90 degrees clockwise in order to access the rear shroud hole to the steering wheel inflator module.
  4. Insert a screwdriver and push the leaf spring in order to release the pin.
  5. Turn the steering wheel 180 degrees counterclockwise in order to access to the remaining rear shroud hole.
  6. Insert a screwdriver and push the leaf spring in order to release the pin.
  7. Remove the steering wheel inflator module by tilting the module rearward from the top in order to access the SIR wiring.
  8. Disconnect the SIR lead wire from the clip on the inflator module.

    CAUTION:

    When you are carrying an undeployed inflator module:

    • Do not carry the inflator module by the wires or connector on the inflator module
    • Make sure the bag opening points away from you

    When you are storing an undeployed inflator module, make sure the bag opening points away from the surface on which the inflator module rests. When you are storing a steering column, do not rest the column with the bag opening facing down and the column vertical. Provide free space for the air bag to expand in case of an accidental deployment. Otherwise, personal injury may result.
