Removal Procedure
Caution: Refer to SIR Caution.
1. Disable the SIR System. Refer to SIR Disabling and Enabling. See: Air Bag(s) Arming and Disarming/Service and Repair
Notice: The wheels of the vehicle must be straight ahead and the steering column in the LOCK position before disconnecting the steering column
or intermediate shaft from the steering gear. Failure to do so will cause the SIR coil assembly to become uncentered, which may cause damage to
the coil assembly.
2. Verify the following before removing the SIR coil:
* The wheels on the vehicle are straight ahead.
* That J 42640 is installed or the ignition switch is in the LOCK position.
3. Remove the steering wheel from the steering shaft.
4. On vehicles with a tilt column, pull the tilt lever straight out from the steering column.
