ON CERTAIN PASSENGER VEHICLES, THE AIR BAG ELECTRONIC CONTROL UNIT (ECU) IS DESIGNED TO SENSE AND DISCRIMINATE FRONTAL IMPACT EVENTS, COMMAND AIR BAG AND SEAT BELT PRETENSIONER DEPLOYMENTS IN A TIMELY MANNER, AND PERFORM CONTINUOUS DIAGNOSTICS OF THE AIR BAG SYSTEM IN THE VEHICLE. DUE TO THE POSSIBLE INSUFFICIENT SEALING OF THE BOTTOM OF AN ELECTROLYTE CAPACITOR, IT IS POSSIBLE FOR IT TO LEAK ELECTROLYTE WITHIN THE AIR BAG ECU. ALSO, IN HIGH HUMIDITY ENVIRONMENTS, THE OPERATION OF THE VEHICLE AIR CONDITIONER CAN CAUSE RAPID COOLING OF THE ECU, WHICH IN TURN MAY CAUSE THE FORMATION OF CONDENSATION WITH THE UNIT.
