Air Bag Systems: Service Precautions

Service Precaution

WARNING: The sensing and diagnostic module (SDM) can maintain sufficient voltage to deploy the airbags and pretensioners for 1 minute after the ignition is OFF and the fuse has been removed. If the airbags and pretensioners are not disconnected, do not begin service until 1 minute has passed after disconnecting power to SDM. If the airbags are disconnected, service can be executed immediately without waiting for 1-minute time period to expire. Failure to temporarily disable the SIR during service can result in unexpected deployment, personal injury and unnecessary SIR repairs.
