Air Bag, Knee Blocker: Removal: Removal
On vehicles equipped with the high voltage system, disconnecting the 12-volt battery negative cable alone will not power down the 12-volt system. You must perform the 12-volt Power Down procedure before proceeding. Failure to follow these instructions may result in possible serious or fatal injury. Refer to ELECTRIC VEHICLE CONTROL SYSTEM, STANDARD PROCEDURE .
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 Knee AirBag (KAB) (also known as the Inflatable Knee Blocker/IKB). 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 KAB 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 .
- Perform the 12-Volt Power Down procedure. Refer to ELECTRIC VEHICLE CONTROL SYSTEM, STANDARD PROCEDURE .
- From below the instrument panel (1), remove the two screws that secure the steering column opening cover (2) and Knee AirBag (KAB) unit to the instrument panel lower reinforcement.
- Pull the cover and KAB down and back from the instrument panel far enough to access the electrical connection that is secured by integral latches to the KAB inflator initiator connector receptacle on the outboard end of the KAB housing.
- Depress the latches on each side of the connector insulator and pull the insulator straight out from the inflator initiator to disconnect it from the connector receptacle.
- Remove the steering column opening cover and KAB from the vehicle as a unit.
