Removal And Installation: Removal
To avoid serious or fatal injury on vehicles equipped with airbags, disable the Supplemental Restraint System (SRS) before attempting any steering wheel, steering column, airbag, seat belt tensioner, impact sensor or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the SRS. Failure to take the proper precautions could result in accidental airbag deployment.
To avoid serious or fatal injury when removing a deployed airbag, rubber gloves, eye protection, and a long-sleeved shirt should be worn. There may be deposits on the airbag cushion and other interior surfaces. In large doses, these deposits may cause irritation to the skin and eyes.
The following procedure is for replacement of an ineffective or damaged Driver AirBag (DAB). If the airbag is ineffective or damaged, but not deployed, review the recommended procedures for Handling Non-Deployed Supplemental Restraints. Refer to STANDARD PROCEDURE . If the DAB has been deployed, review the recommended procedures for Service After A Supplemental Restraint Deployment before removing the airbag from the vehicle. Refer to STANDARD PROCEDURE .
- Disconnect and isolate the negative battery cable(s). Refer to STANDARD PROCEDURE . Wait two minutes for the system capacitor to discharge before continuing service.
- Locate the access hole dimples (2) in the lower surface of the steering wheel (1) hub rear trim cover near each of the steering wheel spokes.NOTE:
The graphic for this procedure shows the Driver AirBag (DAB) mounting/horn switch plate (1) and the retainer spring (3) engaged under the hooks (4) of the armature within the steering wheel hub cavity without the DAB trim cover, cushion, housing and inflator present. This was done to provide graphical clarity of the components involved in DAB retention. The DAB trim cover, cushion, housing and inflator can only be removed as a unit with the mounting/horn switch plate and retainer spring as outlined in the following procedure.
- Using an appropriately sized pin punch or screwdriver pierce the trim cover at the dimple and insert it through one of the steering wheel access holes. A guide and notch (2) integral to each side of the steering wheel hub rear trim cover and the mounting/horn switch plate (1) will assist in directing the tool to the ends of the retainer spring (3).
- When the tool makes contact with the retainer spring (2), push inward (toward the steering column) on the tool far enough to disengage the retainer spring from under the hook (1) of the steering wheel armature.
- Pull the released side of the DAB away from the steering wheel far enough to insert a trim stick or another long and thin obstacle between the released spoke of the DAB trim cover and the steering wheel spoke hub cavity. This will help to prevent the released end of the retainer spring from becoming accidentally engaged again, while the opposite end of the retainer spring is being released.
- Repeat Steps 3 and 4 for the opposite end of the retainer spring.
- Pull the DAB away from the steering wheel far enough to access the steering wheel wire harness connector to the DAB inflator initiators (1).CAUTION:
Do not pull on the clockspring pigtail wires or pry on the connector insulators to disengage them from the Driver AirBag (DAB) inflator initiator connector receptacles. Improper removal of these pigtail wires and their connector insulators can result in damage to the airbag circuits or the connector insulators.
- The clockspring DAB pigtail wire connector insulators (1) are secured by integral latches (3) and a Connector Position Assurance (CPA) lock (2) to the airbag tether cutter and inflator connector receptacles, which are located on the back of the floating horn switch plate and the DAB housing. Pull the lock straight out from the connector insulator, then pull the insulators straight out from the connector receptacles to disengage and disconnect them.
- Remove the DAB and floating horn switch plate from the steering wheel as a unit.
- If the DAB has been deployed, the clockspring and stalk unit as well as the steering column must be replaced. Refer to COLUMN, REMOVAL AND INSTALLATION . Refer to CLOCKSPRING, REMOVAL AND INSTALLATION .
