Seat Belt Tensioner: Service and Repair

Pretensioner Front Seat Belt Removal and Installation

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