The defect
ON CERTAIN PASSENGER VEHICLES, A MICROPROCESSOR IN THE AIR BAG CONTROL MODULE, WHICH ACTIVATES THE FRONT AIR BAGS, THE SIDE AIR BAGS, THE FRONT SEAT SAFETY BELT PRETENSIONERS, AND THE BATTERY SAFETY TERMINAL, MAY HAVE A MALFUNCTION THAT COULD LEAD TO AN UNINTENDED ACTIVATION OF ONE OR MORE OF THESE COMPONENTS.
The risk
UNEXPECTED DEPLOYMENT OF THE AIR BAG(S) COULD CAUSE SERIOUS INJURY IF AN OCCUPANT IS TOO CLOSE TO THE DEPLOYING AIR BAG(S). IN ADDITION, THE BATTERY SAFETY TERMINAL MAY ALSO BE ACTIVATED. IF THAT HAPPENS, THE STARTER CABLE WOULD BECOME DISCONNECTED FROM THE BATTERY, AND THE ENGINE COULD NOT BE RESTARTED.
