Air Bag Control Module: Service and Repair


Supplemental Restraint Sensing and Diagnostic Module Replacement

Caution: If any water enters the vehicle's interior up to the level of the carpet or higher and soaks the carpet, the Sensing and Diagnostic Module (SDM) and the SDM harness connector may need to be replaced. The SDM could be activated when powered, which could cause deployment of the air bag(s) and result in personal injury. Before attempting these procedures, the Supplemental Restraint System must be disabled. Refer to Disabling the SRS Air Bag(s) Arming and Disarming. With the ignition OFF inspect the SDM mounting area, including the carpet. If any significant soaking or evidence of significant soaking is detected, you must:
- Remove all water.
- Repair the water damage.
- Replace the SDM harness connector.
- Replace the SDM.

Failure to follow these procedures could result in possible air bag deployment, personal injury, or otherwise unneeded Supplemental Restraint System repairs.

Caution: Be careful when you handle a Sensing and Diagnostic Module (SDM). Do not strike or jolt the SDM. Before applying power to the SDM:
- Remove any dirt, grease, etc. from the mounting surface
- Position the SDM horizontally on the mounting surface.
- Point the arrow on the SDM toward the front of the vehicle
- Tighten all of the SDM fasteners and SDM bracket fasteners to the specified torque value

Failure to follow the correct procedure could cause air bag deployment, personal injury, or unnecessary Supplemental Restraint System repairs.
