Precautions/Procedu res
SRS Unit Precautions
Take extra care when painting or doing body work inthe area below the dashboard. Avoid direct exDosureof the SRS unit or wiring to heat guns, welding. orsprayang equipment.
Disconnect the airbag connector(s) before discon-necting SRS harness connectors (see page24-1|1J.
After any degree of frontal body damage, or after acollision without airbag deployment, inspect the SRSunit for physical damage. lf it is dented. cracked, ordeformed, replace it.
Be sure the SRS unit is installed securely.
Do not disassemble the SRS unit.
Store the SRS unit in a cool (less than about 104.F/40"C) and dry (less than 80% humidity, no moisture)place. Do not spill water or oil on the SRS unit, andkeep it away from dust.
During installation or replacement, be careful not tobump (impact wrench, hammer, etc.) the area aroundthe SRS unit. The airbag(s) could accidentally deptoyand cause damage or injury.
24-8
Inspection After Deployment
After a collision ln which the airbag(s) was (were)
deployed, replace the SRS unit, and inspect the following:
1. Inspect all the SRS wire harnesses. Replace. don,trepair, any damaged harnesses.
2. Inspect the cable reel for heat damage. lf there is anydamage, replace the cable reel.
3. After the vehicle is completely repaired, turn theignition switch on. lf the SRS indicator light comeson for about six seconds and then goes off. the SRSsystem is OK. lf the indicator light does not functionproperly, go to SRS Troubleshooting.

Wiring Precautions
. Never attempt to modify, splice or repair SRS wiring'
NOTE: SRS wiring can be identified by special yellow
outer Protective covering.
8e sure to install the harness wires so that they are not
oinched or interfering with other parts.
t
Make sure all SRS ground locations are clean and
grounds are securely fastened for optimum metal-to-
metal contact. Poor grounding can cause intermittent
problems that are difficult to diagnose.

. When checking voltage or resistance on this type of
connector the flrst time, it is necessary to remove lne
retainer to insert tester probes from the wire side.
NOTE: lt is not necessary to reinstall the removed
retainer; the terminals wi I stay locked in the connec-
tor housrng.
To remove the retainer, insert a flat tip screwdriver
between connector body and retainer, and carefully
pry out the retainer.
NOTE: Take care not to break the connector.

How To Use This Manual
Troubleshooting Tests
Testing for Voltage Drop
Wires, connectors, and switches are designed
to conduct current wilh a minimum loss of
voltage. A voltage drop of more than one volt
indicates a Droblem.
'1. Place the digital volVohmmeter (DVOM) in
the appropriate DC volts range. Connect
the positive lead to the end of the wire
(or to the connector or switch) closest to
the bafterv.
Connect the negative lead to the other
end of the wire (or the other side of the
connector or switch).
Turn on the components in the circuit.
The DVOM will show the difference
in voltage between the two points. A
difference, or drop, of more than one
volt indicates a oroblem. Check the
circuit for loose, dirty, or bent terminals.
co
Testing lor a Short with a Test Light or DVOM
1. Remove the blown fuse and disconnect
the load.
2. Connect a test light or digital
oltr'ohmmeter
(DVOM), switched to the appropnare DC
volts range, across the tuse lerminals to
make sure voltage is present. You might
have to turn the ignition switch to ON:
check the schematic to see.
<-s80RT TOGFOUNO
Disconnecl lheload here.
Beginning near the luse box, wiggle the
harness. Continue this at convenient ooints
about six inches apart while watching the
test light or DVOM.
Where the test light goes off, or the DVOM
voltage drops to zero, there is a short to
ground in the wiring near that point.
NOTE: Always use a DVOM on high
impedance circuits. A test light may not
glow (even with battery voltage present).
