Air Bag Control Module: Service Precautions

CAUTION: The sensing and diagnostic module (SDM) can maintain sufficient voltage to deploy the airbags for 10 minutes after the ignition is OFF and the AIRBAG fuse has been removed. If the airbags are not disconnected, do not begin service until 70 minutes have passed after disconnecting power to the SDM. If the airbags are disconnected, do begin immediately without waiting for the 10-minute time period to expire. Failure to temporarily disable the SIR system during servicing can result in unexpected deployment, personal injury, and otherwise unneeded SIR system repairs.
