Inflatable Restraint Steering Wheel Module Replacement

REMOVAL PROCEDURE

CAUTION: Refer to SIR Handling Caution in Cautions and Notes.

IMPORTANT: In the event of deployment, inspect the Supplemental Inflatable Restraint (SIR) coil for assembly wire for any signs of scorching, melting or other damage due to excessive heat. If there is excessive damage to coil assembly, replace the coil assembly.




1. Disable the supplemental inflatable restraint (SIR).

CAUTION: Refer to Battery Disconnect Caution in Cautions and Notes.

2. Remove the mounting bolt hole caps
3. Loosen the steering wheel inflator module TORX(R) bolts completely.


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.
