Air Bag Control Module: Service and Repair

Sensing and Diagnostic Module (SDM) Removal and Installation

Removal

WARNING: During service procedure, be very careful when handling the SDM. Never strike or jar the SDM. Never power the supplemental inflatable restraints (SIR) when the SDM is not rigidly attached to the vehicle. All SDM mounting bolts must be carefully tightened, and the arrow on the SDM must be point toward the front of the vehicle to ensure proper operation of the SIR. The SDM could be activated if it is powered when it is not rigidly attached to the vehicle, resulting in unexpected deployment and possible injury.

CAUTION: If the vehicle interior has been exposed to extensive water intrusion such as water leaks, driving through high water, flooding or other causes, then the SDM and SDM connector may need to be replaced. With the ignition OFF, inspect the area of SDM, including the carpet. If any significant soaking or evidence of previous soaking is detected, the water must be removed, the water damage repaired and the SDM and SDM connector must be replaced. Before attempting any of these repairs, the SIR must be disabled. Refer to Disabling the Supplemental Inflatable Restraints (SIR).
