J 42640 Steering Column Antirotation Pin

Caution: When performing service on or around SIR components or SIR wiring, follow the procedure to temporarily disable SIR system. Refer to Disabling/Enabling SIR System in Restraints. Failure to follow procedures could result in possible air bag deployment, personal injury or otherwise unneeded SIR repairs.

Caution: This vehicle is equipped with a Supplemental Inflatable Restraint (SIR) System. Failure to follow the correct procedure could cause the following conditions:

•	Air bag deployment

•	Personal injury

•	Unnecessary SIR system repairs

In order to avoid the above conditions, observe the following guidelines:

•	Refer to SIR Component Views in order to determine if you are performing service on or near the SIR components or the SIR wiring.

•	If you are performing service on or near the SIR components or the SIR wiring, disable the SIR system. Refer to Disabling the SIR System.

1. Disable the SIR System. Refer to Disabling the SIR System in Restraints.



2. Insert the J 42640 into the steering column access hole in order to lock the steering column and in order to maintain correct orientation.
3. Insert a flat-bladed screwdriver into one of the 4 openings in the back of the steering wheel.
4. Turn the screwdriver counterclockwise in order to disengage the wire from the slot in the inflator module fastener.
5. Repeat steps 2-4 for each of the 4 openings in the back of the steering wheel.
6. Gently pull the driver inflator module away from the steering wheel.




Important: Observe the following routing positions for correct reassembly:

•	The driver inflator wire routing positions

•	The redundant control wire routing positions

•	The horn wire routing positions

7. Disconnect the following components:

•	The connector position assurance (CPA)

•	The driver inflator module electrical connector

8. Remove the horn ground lead (2) from the threaded hole in the steering wheel (6).
9. Rotate the horn contact lead counterclockwise 1/4 turn.
10. Remove the horn contact lead from the steering column cam tower.
11. Remove the inflatable restraint steering wheel module (5).

Caution: When carrying a live inflator module, make sure the bag opening is pointed away from you. Never carry the inflator module by the wires or connector on the side of the module. In case of an accidental deployment, the bag will then deploy with minimal chance of injury. When placing a live inflator module on a bench or other surface, always face the bag up, away from the surface. This is necessary so that a free space is provided to allow the air bag to expand in the unlikely event of accidental deployment. Otherwise personal injury may result.

1. Install the horn ground lead (2) into the lower left threaded hole in the steering wheel (6).
2. Install the horn contact lead (2) into the steering column cam tower.
3. Rotate the horn contact 1/4 turn clockwise in order to lock the contact.
4. Connect the following components:

•	The connector position assurance (CPA)

•	The driver inflator module electrical connector

Important: Route the following wires correctly:

•	The drive inflator wires

•	The redundant control wires

•	The horn wires

5. Align the driver inflator module fasteners to the steering column fastener holes.
6. Push the driver inflator module firmly into the steering column in order to engage the fasteners.



7. Remove the J 42640 from the steering column access hole.
8. Enable the SIR system. Refer to Enabling the SIR System in Restraints
