Precautions/Procedu res
SRS Unit Precautions
Take extra caro when painting or doing body work in
the area below the dashboard. Avoid direct exposure
of the SRS unit or wiring to heat guns, welding, or
spraying equipment.
Disconnect the airbsg connector(s) before discon-
necting SRS harness connectors (see page 23-2851.
After any degree of frontal body damage, or after a
collision without airbag deployment, inspect the SRS
unit for physical damage. lf it is dented, cracked, or
deformed, reDlace it.
Be sure the SRS unit is installed securelv.
Do not disassemble the SRS unit.
Store the SRS unit in a cool (lass than about
104'F/40"C) and dry (less than 80% humidity, no mois-
ture) place, Do not spill water or oil on the SRS unit,
and keeD it awav trom dust.
During installation or r6placement, be careful not to
bump {impact wrench, hammer, etc.) the area around
the SRS unit. The airbags could accidentally deploy
and cause damsge or injuries,
v
Inspection After Deployment
After a collision in which the airbags w6re deployed,
replace the SRS unit, and inspect the following:
1, Inspect all the SRS wire harnesses. Replace, don't
repair, any damaged harnesses
2. Inspect the cable reel for heat damage. lf there is any
damage. replace the cable reel.
3. After the vehicle is completely repairod, turn the
ignition switch ON {ll). lf the SRS indicator light
comes on for about six seconds and then goes off,
the SRS system is OK. lf the indicator light does not
function properly. go to SRS Troubleshooting.

How To Use This Manual
Symbols
Ground - "G"
This symbol means the end of
the wire is attached (grounded) Ito the car frame or to a metal Ipart connected to the f rame. \I orol
,
Each wire ground (G) ," -/numbered for reference.
Q,(Switches
These switches move
together; the broken straight
line between them means thev
are mechanically connected.
Other types of switches are
controlled by a coil or a solid
state circuit. Unless otherwise
noted, all switches are shown
in their normal (rest) position,
with power off .
This ground symbol (dot
and 3 lines) overlapping the
component means the housing
of the component is grounded
to the car f rame or to a metal
part connected to the f rame.
This symbol represents
the bus bar inside a ground
connector. The dots a

bus bar and metal (grounded)
part of the car.
Terminals - "T"

Solid-state
Fuses
This means power is supplied
when the ignition switch is in ON (ll).
Diodes
A rectifier diode works like a one
way valve. lt allows current to
flow only in the dlrection of the
arrow.
A Zener diode blocks reverse
currenl at normal voltages just like
a rectifier diode. At high voltages,
however, a Zener diode allows
current to flow in reverse.
Q,(
Each 'T" terminal (ring type)
is numbered for reference ano
location. A "T" terminal is
secured with a screw or bolt.
Shielding
This represents RFI
(Radio Frequency
Interf erence) shielding
around a wire. The
shielding is always
connected to ground.

A/C Gompressor Controls (conrd)
- How the Circuit Works
Battery voltage is supplied through fuse 56 to the
A,/C compressor clutch relay contacts at all times.
With the ignition switch in ON (ll), voltage is applied
to the coil of the A,/C compressor clutch relay
through fuse 17. When you push the A,/C switch
ON, and the heater fan switch is in posation 1, 2, 3,
or 4, a "ground" input is provided to the engine or
powertrain control module (ECM or PCM) through
the A,/C thermostat and the A,/C pressure switch.
The A,/C compressor clutch relay is grounded by the
engine or powertrain control module (ECM or PCM).
When energized, the A,/C compressor clutch relay
allows battery voltage to turn on the A,/C
comDressor clutch,
The A,/C ON indicator light comes on when the A"/C
system is requested.
A,/C Thermostat
The A,/C thermostat is located on the evaoorator
housing. The AJC thermostat turns off the A,/C
compressor clutch if the temperature at the
evaporator goes below 3'C (37'F). This prevents
condensation from freezing on the evaporator fins
and blocking the air delivery into the passenger
compartment. The blower motor will keep running
when the sensor lurns off the compressor.
A,/C Pressure Switch
The A,/C pressure switch is located in the condenser
outlet line where refrigerant is in a high
temperature/high pressure liquid state. The switch
will sense abnormally high or low pressure, and
open the circuit. This removes ground, and the
compressor will stop running.
Refer to the Service Manual (Section 22,
Air Conditioning) for specific tests or
troubleshooting procedures.
62-2

Fans (cont'd)
- How the Gircuit Works
When the ignition switch is in ON (ll), voltage is
applied to the coils of the radiator fan relay and the
condenser fan relay (with A,/C) through fuse 17.
Whenever a ground is provided to the radiator fan
relay and condenser fan relay, the relays are
energized, turning on the radiator fan motor and
condenser fan motor. The relays can be grounded
by the radiator fan switch, engine or powertrain
control module (ECM or PCM) (USA), or the A,/C
and heater lan switches via the A'lC pressure switch
and the A,/C lhermostat.
A,/C Thermostat
The A,/C thermostat is located on the evaporator
housing. The A/C thermostat turns oft the A/C
compressor clutch it the temperature at the
evaporator goes below 3'C (37"F). This prevents
condensalion from freezing on the evaporator fins
and blocking the air delivery into the passenger
compartment. lt the temperature goes below 3'C
(37'F) turning off the A"/C thermostat, and the
BLU/RED wire at the A,/C diode was the only wire
providing ground to the condenser and radiator
fan relays (A,/C switch on, heater fans switch on,
radiator fan switch open, and ECM or PCM fan
controi output not grounded), the relay will
deenergize removing voltage from the condenser
and radiator fan motors causing them to stop
running.
A,/C Pressure Switch
The AJC oressure switch is located in the condenser
outlet line where refrigerant is in a high
temperature/high pressure liquid state. The A,/C
switch turns off the A,/C compressor clutch if it
senses abnormally high or low pressure. lf the A'lC
pressure switch opens, and the BLU/RED wire at
the A/C diode was the only wire providing ground
to the condenser and radiator fan relays (L/C switch
on, heater fans switch on, radiator lan switch open'
and ECM or PCM fan control output not grounded),
the relay will deenergize removing voltage from the
condenser and radiator fan motors causing them to
stop running.
A./C Diode
This diode orevents the radiator fan switch f rom
grounding the "A'lC ON" input to the engine or
powertrain control module (ECM or PCM).
Refer to the Service Manual (Section 23, Electrical)
for specific tests or troubleshooting procedures.
