NOTICE
Trouble diagnoses indicates work procedures required to diag-
nose problems effectively. Observe the following instructions
before diagnosing.
1) Before performing trouble diagnoses, read the ªPrelimi-
nary Checkº, the ªSymptom Chartº or the ªWork Flowº.
2) After repairs, re-check that the problem has been com-
pletely eliminated.
3) Refer to Component Parts and Harness Connector Loca-
tion for the Systems described in each section for
identification/location of components and harness con-
nectors.
4) Refer to the Circuit Diagram for Quick Pinpoint Check.
If you need to check circuit continuity between harness
connectors in more detail, such as when a sub-harness
is used, refer to Wiring Diagram in each individual sec-
tion and Harness Layout in EL section for identification
of harness connectors.
5) When checking circuit continuity, ignition switch should
be in the ªLOCKº position.
6) Before checking voltage at connectors, check battery
voltage.
7) After accomplishing the Diagnostic Procedures and
Electrical Components Inspection, make sure that all
harness connectors are reconnected as they were.

Nickel Metal Hydride Battery Replacement
CONSULT-II contains a nickel metal hydride battery. When replacing the battery obey the following:
WARNING:
Replace the nickel metal hydride battery with genuine CONSULT-II battery only. Use of another bat-
tery may present a risk of fire or explosion. The battery may present a fire or chemical burn hazard
if mistreated. Do not recharge, disassemble of dispose of in fire.
Keep the battery out of reach of children and discard used battery conforming to the local regula-
tions.

Precautions for Servicing Compressor
lPlug all openings to prevent moisture and foreign matter from entering.
lWhen the compressor is removed, store it in the same position as it is when mounted on the car.
lWhen replacing or repairing compressor, follow ªMaintenance of Lubricant Quantity in Compres-
sorº exactly. Refer to HA-102.
lKeep friction surfaces between clutch and pulley clean. If the surface is contaminated, with
lubricant, wipe it off by using a clean waste cloth moistened with thinner.
lAfter compressor service operation, turn the compressor shaft by hand more than five turns in
both directions. This will equally distribute lubricant inside the compressor. After the compres-
sor is installed, let the engine idle and operate the compressor for one hour.
lAfter replacing the compressor magnet clutch, apply voltage to the new one and check for nor-
mal operation.

Operational Check
The purpose of the operational check is to confirm that the sys-
tem operates as it should. The systems which are checked are
the blower, mode (discharge air), intake air, temperature
decrease, temperature increase.
CONDITIONS:
Engine running at normal operating temperature.
PROCEDURE:
1. Check blower
1) Turn fan control knob to 1-speed.
Blower should operate on 1-speed.
2) Then turn fan control knob to 2-speed.
3) Continue checking blower speed until all four speeds are
checked.
4) Leave blower on 4-speed.
2. Check discharge air
1) Turn mode control knob.
2) Confirm that discharge air comes out according to the air
distribution table at left.
Refer to ªDischarge Air Flowº in ªDESCRIPTIONº (HA-23).

Trouble Diagnoses for Abnormal Pressure
Whenever the system's high and/or low side pressure is abnormal, diagnose using a manifold gauge. The
marker above the gauge scale in the following tables indicates the standard (normal) pressure range. Since
the standard (normal) pressure, differs from vehicle to vehicle, refer to HA-35 (ªAmbient air temperature-to-
operating pressure tableº).
Gauge indication Refrigerant cycle Probable cause Corrective action
Both high and low-pressure
sides are too high.
AC359A
lPressure is reduced soon
after water is splashed on
condenser.Excessive refrigerant charge
in refrigeration cycle.Reduce refrigerant until
specified pressure is
obtained.
Air suction by cooling fan is
insufficient.Insufficient condenser cooling
performance
"
p1Condenser fins are
clogged.
p2Improper cooling fan
rotation.
lClean condenser.
lCheck and repair cooling
fan as necessary.
lLow-pressure pipe is not
cold.
lWhen compressor is
stopped high-pressure
value quickly drops by
approximately 196 kPa (2.0
bar, 2 kg/cm
2, 28 psi). It
then decreases gradually
thereafter.Poor heat exchange in con-
denser
(After compressor operation
stops, high pressure
decreases too slowly.)

Engine tends to overheat. Engine cooling systems mal-
function.Check and repair each
engine cooling system.
lAn area of the low-pres-
sure pipe is colder than
areas near the evaporator
outlet.
lPlates are sometimes cov-
ered with frost.
lExcessive liquid refrigerant
on low-pressure side
lExcessive refrigerant dis-
charge flow
lExpansion valve is open a
little compared with the
specification.
