E 150 1/2 Ton Van V6-4.2L VIN 2 (1997)
Impact Sensor: Description and Operation
WARNING: The ECS and primary crash sensor orientation is critical for proper system operation. If a vehicle equipped with an SRS system
has been involved in a collision where the radiator grille, frame rails or right cowl panel has been damaged, inspect the mountings and brackets
for deformation. If damaged, the primary crash sensor or ECS must be replaced whether or not the air bag modules have deployed. in addition,
make sure the area of the primary crash sensor mounting is restored to its original condition.
PURPOSE
The air bag system is designed to:
-
operate in frontal or front-angled collisions.
-
activate the air bags in a crash with severe frontal deceleration, more severe than hitting a parked car of similar size and weight head-on at
about 45 km/h (28 mph).
-
sense the severity of the crash rather than vehicle speed; thus some frontal collisions at speeds above 45 km/h (28 mph) may not be severe
enough to require air bag inflation.
NOTE: If the primary crash sensor is undamaged after a collision, it will automatically reset and can be reused.
