Circuit Operation
The SRS consists of the SRS unit, the driver air bag as-
sembly, the SRS coil assembly, the passenger air bag
assembly and the “AIR BAG” warning light in the meter
assembly. The SRS unit, SRS coil assembly (driver
side only), driver air bag assembly, passenger air bag
assembly and connector wire make up the deployment
loops. The function of the deployment loops is to supply
current through air bag assembly, which will cause de-
ployment of the air bags in the event of a frontal crash of
sufficient force, up to 30 degrees off the centerline of the
vehicle. The air bag assemblies are only supplied
enough current to deploy when the SRS unit detects ve-
hicle velocity changes severe enough to warrant de-
ployment.
The SRS unit contains a sensing device which converts
vehicle velocity change to an electrical signal. The elec-
trical signal generated is processed by the SRS unit and
then compared to a value stored in memory. When the
generated signal exceeds the stored value, the SRS
unit will cause current to flow through the air bag as-
sembly deploying the air bags.
Refer to Section 9J of the Workshop Manual for further
supplemental restraint system diagnosis.
