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 9 in Air Bag(s) Arming and Disarming.

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.
- If the vehicle interior is exposed to moisture and becomes soaked up to the level of the sensing and diagnostic module (SDM), the SDM and SDM harness connector must be replaced. The SDM could be activated when powered, which could cause airbag deployment and result in personal injury.
