Air Bag Control Module: Service and Repair

INFLATABLE RESTRAINT SENSING AND DIAGNOSTIC MODULE REPLACEMENT

REMOVAL PROCEDURE
1. Disable the SIR system. Refer to SIR Disabling and Enabling Zone 8.

CAUTION: Do not strike or jolt the inflatable restraint sensing and diagnostic module (SDM). Before applying power to the SDM, make sure that it is securely fastened with the arrow facing toward the front of the vehicle. Failure to observe the correct installation procedure could cause SIR deployment, personal injury, or unnecessary SIR system repairs.

2. Remove the floor console.
3. Cut the carpet along the "I" cut pattern over the inflatable restraint sensing and diagnostic module (SDM).
4. Fold the carpet back to expose the SDM.
