IMPACT SENSOR
DESCRIPTION
FRONT
Two front impact sensors (1) are used on this model,
one each for the left and right sides of the vehicle.
These sensors are mounted remotely from the impact
sensor that is internal to the Occupant Restraint Con-
troller (ORC). Each front sensor is secured with two
flanged hex nuts to two studs on the backs of the right
and left vertical members of the radiator support within
the engine compartment. The sensor housing has an
integral connector receptacle (2), an integral anti-rota-
tion pin (3), and two integral mounting holes (4) with
metal sleeves to provide crush protection.
The right and left front impact sensors are identical in construction and calibration. A label on the sensor is imprinted
with an arrow, which should always be pointed forward in the vehicle. A cavity in the center of the molded plastic
impact sensor housing contains the electronic circuitry of the sensor which includes an electronic communication
chip and an electronic impact sensor. Potting material fills the cavity and a stamped cover (5) is crimped over the
cavity to seal and protect the internal electronic circuitry and components. The front impact sensors are each con-
nected to the vehicle electrical system through a dedicated take out and connector of the headlamp and dash wire
harness.
The impact sensors cannot be repaired or adjusted and, if damaged or faulty, they must be replaced.
SIDE
Four side impact sensors (2) are used on this model
when it is equipped with the optional side curtain air-
bags, two each for the left and right sides of the vehi-
cle. These sensors are mounted remotely from the
impact
sensor
that
is
internal
to
the
Occupant
Restraint Controller (ORC). Each side sensor is
secured with two screws to the inner right or left B-pil-
lar and C-pillar beneath the trim within the passenger
compartment. The sensor housing has an integral con-
nector receptacle (3), an integral anti-rotation pin (4),
and two integral mounting holes (1) with metal sleeves
to provide crush protection.
