Steering Wheel Inflatable Restraint Module Coil Replacement Vin #14125814 and Less

Removal Procedure

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.
