Body Electrical
General Troubleshooting Information (cont'd)
Check for loose retainer (A) and rubber seals (B).
The backs of some connectors are packed with
dielectric grease. Add grease if necessary. lf thegrease is contaminated, replace it.
lnsert the connector all the way and make sure it is
securelv locked.
Position wires so that the open end of the cover faces
oown.
22-4
Handling Wires and Harnesses. Secure wires and wire harnesses to lhe frame with
their respective wire ties at the designated locations.. Remove clips carefully; don't damage their locks (A).
Slip pliers (A) under the clip base and through the
hole at an angle, then squeeze the expansion tabs to
release the clip.
After installing harness clips, make sure the harness
doesn't interfere with any moving pans.
Keep wire harnesses away from exhaust pipes and
other hot parts, from sharp edges of brackets and
holes, and from exposed screws and bolts.
Seat grommets in their grooves properly {A). Do not
leave grommets distorted (B).

sRs
System Description (cont'dl
SRS Operation
The main circuit in the SRS unit senses and judges the force of impact and, if necessary. ignites the inflator charges. lf
battery voltage is too low or power is disconnected due to the impact, the voltage regulator and the back-up power
circuit, respectively, will keep voltage at a constant level.
For the SRS to operate:
Seat Belt Tensioners and Seat Belt Buckle Tensioners
(1) A front impact sensor must activate and send electric signals to the microprocessor.
(2) The microprocessor must compute the signals and send them to the tensioners.
(3) The charges must ignite and deploy the tensioners.
Driver's and Front Passenger's Airbagls)
(1) A front impact sensor musl activate. and send electric signals to the microprocessor.
(2) The microprocessor must compute the signals. and depending on the severity of the collision and whether the seat
belt buckle swilch is ON or OFF, it sends the appropriate signals to the airbag inflator(s).
(3) The inflators that received signals must ignite and deploy the airbags.
Side Airbaglsl( 1) A side impact sensor must activate, and send electric signals to the microprocessor.
(2) The microprocessor must compute the signals and send them to the side airbag inflator(s). However, the
microprocessor cuts off the signals to the front passenger's side airbag if the OPDS unit determines that the tront
passenger's head is in the deployment path of the side airbag.
(3) The inflator that received the signal must ignite and deploy the side airbag.
