Air Bag Control Module: Service and Repair
Important Preliminary Precautions
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 did, 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 SIR system repairs.
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 SIR system must be disabled. Refer to Disabling the SIR System. 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 perform the following steps:
^
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 SIR system repairs. See: Body and
