    Removal Procedure


      Object Number: 640349  Size: SH

      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.

       

     

    1. On the back side of the steering wheel are 4 openings for removing the driver inflator module.
    2. Turn the steering wheel until 2 of the openings are on the top.
    3. Adjust and install J 44298 into 2 of the holes.

      Important: Seat the air bag removal tool all the way in to perform properly.

    4. Push the handle back towards the instrument panel (I/P) releasing the 2 spring loaded fasteners at the same time.
    5. Turn the steering wheel and repeat the same steps for the other 2 openings.
    6. Pull the module gently away from the steering wheel.
    7. You can use a small flatblade screwdriver in place of the special tool.
      Object Number: 294362  Size: SH

      Important: Note the driver inflator wire routing positions, the redundant control routing positions, and the horn wire routing positions for the correct re-assembly.

    8. Remove the connector position assurance (CPA) and remove the inflator module electrical connector.
    9. Remove the horn contact lead.
    10. Remove the inflatable restraint steering wheel module.
