Removal

WARNING: Always carry or place a live air bag module with the air bag and deployment door/trim cover/tear seam pointed away from the body. Do not set a live air bag module down with the deployment door/trim cover/tear seam face down. Failure to follow these instructions may result in serious personal injury in the event of an accidental deployment.

WARNING: Never probe the electrical connectors on air bag, Safety Canopy(R) or side air curtain modules. Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.

WARNING: Do not paint any air bag module trim covers or deployment doors. Paint may cause the air bag to deploy incorrectly. Failure to follow this instruction may increase the risk of serious personal injury or death in a crash.

NOTICE: Make sure the steering wheel spring clips retaining the driver air bag module are disengaged from each of the 4 locking pins on the driver air bag module before removing the driver air bag module from the steering wheel. Failure to do so will damage the driver air bag module and steering wheel.

NOTE: The air bag warning indicator illuminates when the correct Restraints Control Module (RCM) fuse is removed and the ignition is ON.

NOTE: The Supplemental Restraint System (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.

1. Depower the SRS. For additional information, refer to Supplemental Restraint System (SRS) Depowering and Repowering Supplemental Restraint System (SRS) Depowering and Repowering.

2. NOTE: A tool that has a blunt end, such as a 4.0 mm (0.15 in) Allen wrench, is better able to disengage the steering wheel spring clip from the driver air bag module locking pins.

Using a 4 mm (0.15 in) Allen wrench or suitable tool, place 2 marks on the tool as an aid to remove the driver air bag module. One mark should be approximately 35 mm (1.37 in) from the end of the tool with the second mark approximately 45 mm (1.77 in) from the end of the tool.





3. NOTE: The steering wheel rear cover has internal guides that direct the tool to the spring clip. Allow the steering wheel rear cover to guide the tool, minimal force is needed.

Gently insert the tool into a steering wheel rear cover upper access hole until the end of the tool comes into contact with an obstruction. The 45 mm (1.77 in) mark on the tool should be even or close to even with the steering wheel rear cover. If the 45 mm (1.77 in) mark on the tool is not even or close to even with the steering wheel rear cover, remove the tool from the steering wheel and carry out the step once again to correctly position the tool.
- If the 45 mm (1.77 in) mark on the tool goes into the steering wheel rear cover, the tool was directed past the steering wheel spring clip. Use a tool of a slightly larger diameter or, using the internal guides of the steering wheel rear cover, insert the tool to the 45 mm (1.77 in) mark and proceed to the next step.





4. NOTE: The steering wheel is removed for clarity. The upper corner of the steering wheel rear cover is cutaway to show the internal guides and the steering wheel spring clip.

With the tool correctly positioned, remove the tool approximately 2-3 mm (0.07-0.11 in) from the access hole then gently push the tool forward (toward front of vehicle). This puts the tool in the best position to disengage the steering wheel spring clip from the driver air bag module locking pin.





5. NOTE: Make sure to disengage the steering wheel spring clip from the driver air bag module locking pin before gently pulling the corresponding corner of the driver air bag module. No or very little force is needed to separate the corresponding corner of the driver air bag module from the steering wheel once the spring clip is disengaged from the locking pin.

NOTE: When the steering wheel spring clip is disengaged from the first locking pin, the corresponding corner of the driver air bag module will only separate 2-4 mm (0.07-0.15 in) from the steering wheel. The driver air bag module will separate more noticeably as subsequent locking pins are disengaged.

Push the tool deeper into the access hole (approximately 4-8 mm [0.15-0.31 in]) with enough force to disengage the steering wheel spring clip from the driver air bag module locking pin. The corresponding corner of the driver air bag module should pop up once the spring clip is disengaged from the locking pin. Gently pull the corresponding corner of the driver air bag module to make sure the locking pin does not re-engage the spring clip. Remove the tool from the access hole. Discontinue pulling on the corresponding corner of the driver air bag module.

- If the corresponding corner of the driver air bag module does not easily separate from the steering wheel, the spring clip is not disengaged from the locking pin. Repeat the steps to position the tool correctly and disengage the spring clip from the locking pin.





6. NOTE: The steering wheel rear cover has internal guides that assist in directing the tool to the correct location. Allow the steering wheel rear cover to guide the tool, minimal force is needed.

Working on the same side of the steering wheel, gently insert the tool into a steering wheel rear cover lower access hole until the end of the tool comes into contact with an obstruction. The 35 mm (1.37 in) mark on the tool should be even or close to even with the steering wheel cover. If the 35 mm (1.37 in) mark on the tool is not even or close to even with the steering wheel cover, remove the tool from the access hole and carry out the step again to position the tool correctly.

- If the 35 mm (1.37 in) mark on the tool goes into the steering wheel rear cover, the tool was inserted past the steering wheel spring clip. Use a tool of a slightly larger diameter or, using the internal guides of the steering wheel rear cover, insert the tool to the 35 mm (1.37 in) mark and proceed to the next step.





7. NOTE: The steering wheel is removed for clarity. The lower corner of the steering wheel rear cover is cutaway to show the internal guides and the steering wheel spring clip.

With the tool correctly positioned, remove it approximately 2-3 mm (0.07-0.11 in) out of the access hole then gently push the tool forward (toward front of vehicle). This puts the tool in the best position to disengage the steering wheel spring clip from the driver air bag module locking pin.





8. NOTE: Make sure to disengage the steering wheel spring clip from the driver air bag module locking pin before gently pulling the corresponding corner of the driver air bag module. No or very little force is needed to separate the corresponding corner of the driver air bag module from the steering wheel once the spring clip is disengaged from the locking pin.

Push the tool deeper into the access hole (approximately 3-6 mm [0.11-0.23 in]) with enough force to disengage the steering wheel spring clip from the driver air bag module locking pin. The corresponding corner of the driver air bag module should pop up once the spring clip is disengaged from the locking pin. Gently pull the corresponding corner of the driver air bag module to make sure the locking pin does not reengage the spring clip. Remove the tool from the access hole. Discontinue pulling on the corresponding corner of the driver air bag module.

- If the corresponding corner of the driver air bag module does not easily separate from the steering wheel the spring clip is not disengaged from the locking pin. Repeat the necessary steps to correctly position the tool and disengage the spring clip from the locking pin.





9. NOTE: Disengage the steering wheel spring clips from the 2 locking pins on one side of the driver air bag module before proceeding to the other side.

Repeat the above steps to disengage the 2 remaining driver air bag module locking pins.
