Prove Out System

To prove out system, turn ignition switch from OFF to RUN position and visually monitor the AIR BAG warning light with air bag modules installed. The Electronic Crash Sensor (ECS) module illuminates the AIR BAG warning light for 4-8 seconds and then turns it off. If the AIR BAG warning light does not illuminate, stays on or flashes at any time, a fault has been detected by the ECS module and further service is needed.
