1. Disable the SIR system. Refer to SIR Disabling and Enabling Zone 3.
  2. If equipped with steering column tilt, adjust the steering wheel to the lowest position.
  1. The back side of steering wheel has 4 openings for access to the driver supplemental inflatable restraint (SIR) module retainers. Turn the steering wheel until 2 of the openings are accessible, straight above the steering column.
  2. Adjust and install the J 44298 into the top 2 openings.

IMPORTANT: The driver air bag removal tool must be seated correctly to function.

  1. Push the handle towards the instrument panel to release both module mounting posts from the retainer.
  2. Repeat this procedure for the remaining openings.
  1. Pull the module gently away from the steering wheel.
  2. Remove the connector position assurance (CPA) for each module electrical connector.
  3. Disconnect the yellow SIR coil lead wire connectors from the module.
  1. Rotate the horn wire (4) counterclockwise until the wire unlocks from the cam tower post. Remove the horn wire from the steering wheel.
  2. Remove the driver SIR module (5).
  3. 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.

INSTALLATION PROCEDURE

  1. Position the horn wire (4) into the cam tower post. Rotate the horn wire clockwise until locked. The horn wire must be below the top, left, module mounting post.
  1. Connect the yellow SIR coil lead wires to the module connectors. Connect pink to pink and gray to gray.
  2. Install the CPA to each connector.
  1. Make sure the wires are routed and secured correctly:
  2. Secure the black redundant controls connector (2) to the feature at the 6 o'clock position on the steering wheel shroud. For the base steering wheel, the feature is at the 5 o'clock position.
  3. Route the yellow SIR coil lead wires counterclockwise away from the 4 module mounting holes (1,3,5) and away from the center steering wheel nut. Insert the wire bundle into the retainer (6).
  1. Install the 4 mounting posts on the module to the 4 holes in the steering wheel:
  2. Set the left and right sides of the module evenly to the steering wheel.
  3. Press evenly on both sides until a clicking sound is heard.

  1. Enable the SIR system. Refer to SIR Disabling and Enabling Zone 3.

Removal Procedure

  1. Disable the SIR system.
  2. Remove the inflatable restraint steering wheel module.
  3. Remove the steering wheel
  4. Remove the steering wheel controls wire harness from the retainers in the aluminum insert and plastic back shroud.
  1. Remove the back shroud screws and the back shroud on the back of the steering wheel
  1. Carefully push on the back of theradio control switch through the access opening in the back of the steering wheel switch pocket.
  2. Disconnect the electrical connector from the back of the radio control switch.
