AIR CONDITIONING (OPTIONAL) 1B-31
INSPECTION
1) Connect battery positive (+) cable to terminal “b” and battery
negative (–) cable to terminal “c” as shown.
2) Using ohmmeter, check continuity between terminal “a” and
terminal “b” at specified temperature as shown.
Rear A/C evaporator temperature controller specification :
“A” : Approximately 3.5 °C (38.3 °F)
“B” : Approximately 5.0 °C (41 °F)
INSTALLATION
Reverse removal procedure to install rear A/C evaporator temper-
ature controller noting the following instruction.
When the rear A/C evaporator thermistor (temperature sen-
sor) removed, it should be reinstalled in original position.
Refrigerant Pipes and Hoses
INSPECTION
Use a leak tester to check hoses and pipes for any gas leakage.
Check each hose or pipe clamp for tightness. Retighten or replace loose clamp as required, if any.
REMOVAL
1) Recover refrigerant by using recovery and recycling equipment. Be sure to follow the instruction manual for
the equipment.
The amount of compressor oil removed must be measured and the same amount must be added to the sys-
tem when reinstalling.
2) Replace defective hose or pipe.
INSTALLATION
Reverse removal procedure to install refrigerant line noting the following instruction.
Evacuate and charge system. Refer to “EVACUATING” and “CHARGING” in this section.
CAUTION:
As soon as the above hose or pipe is disconnected, cap its opened fitting to prevent moisture and
dust from entering.
NOTE:
Remove EVAP canister and fuel tank cover, if necessary

1B-38 AIR CONDITIONING (OPTIONAL)
Compressor Assembly
INSPECTION
1) Install manifold gauge set (1) as shown in the figure.
2) Close Hi (4) and Lo (5) side valves.
3) Run engine at fast idle.
4) Check compressor for the following items.
If any of the above checks indicated a defect, repair com-
pressor.
High pressure gauge reading is not low and low pressure
gauge reading is not higher than normal.
Metallic sound.
Leakage from compressor. CAUTION:
None of refrigerant, compressor oil and component parts is interchangeable between two types of
A/C: one using CFC-12 (R-12) and the other using HFC-134a (R-134a).
For identification between these two types, refer to page 66.
When replenishing or changing refrigerant and compressor oil and when replacing parts, make sure
that the material or the part to be used is appropriate to the A/C installed in the vehicle being serviced.
Use of incorrect refrigerant or compressor oil will result in leakage of refrigerant, damage in parts or
other faulty condition.
When servicing the compressor, keep dirt or foreign material away from getting on or into the com-
pressor parts and system. Clean tools and a clean work area are important for proper service.
The compressor connection and the outside of the compressor should be cleaned before any “On-
vehicle” repair or before removal of the compressor. The parts must be kept clean at all times and any
parts to be reassembled should be cleaned with Trichloromethane, naphtha, kerosene or equivalent
solvent and dried with dry air. Use only lint free cloths to wipe parts.
The operations described are based on bench overhaul with compressor removed from the vehicle,
except as noted. They have been prepared in order of accessibility of the components.
When compressor is removed from the vehicle for servicing, the oil remaining in the compressor
should be discarded and new refrigerant oil added to the compressor.
Minor repair procedures may be done on the vehicle without discharging the system. Major repair pro-
cedures require that the system be discharged of refrigerant.

Hydraulic Pressure in P/S Circuit
Hydraulic pressure check
1) After cleaning joint of high pressure hose and P/S pump
thoroughly, disconnect hose from pump and install special
tool (oil pressure gauge, attachment and hose).
Special tool
(A) : 09915-77410
(B) : 09915-77420
2) Check each connection for fluid leakage and bleed air.
Refer to “AIR BLEEDING PROCEDURE” in this section.
3) With engine idling, turn steering wheel and warm up engine
till temperature of fluid in P/S fluid reservoir rises to 50 –
60°C (122 – 140°F).
4) Check back pressure by measuring hydraulic pressure with
engine idling and hands off steering wheel.
When back pressure is higher than specified values, check
control valve and piping for clogging.
Back pressure :
Lower than 1000 kPa (10 kg/cm
2, 142 psi) CAUTION:
Take care not to cause damage to A/C condenser during
service operation, if equipped.

5) Check relief pressure.
a) Increase engine speed to about 1500 r/min (rpm). Close
gauge valve gradually while watching pressure increase
indicated by gauge and take reading of relief pressure
(maximum hydraulic pressure).
When it is higher than specified values, possible cause is
malfunction of relief valve.
When it is lower than specified values, possible cause is
either failure of P/S pump or settling of relief valve spring.
Relief pressure (when gauge valve is closed) :
7650 – 8350 kPa (76.5 – 83.5 kg/cm
2, 1088 – 1187 psi)
b) Next, open gauge valve fully and increase engine speed to
about 1500 r/min (rpm). Then turn steering wheel to the left
or right fully and take reading of relief pressure.
When it is higher than specified values, possible cause is
malfunction of relief valve.
When it is lower than specified values, possible cause is
failure in steering gear box. Replace gear box.
Relief pressure (when gauge valve is opened) :
7650– 8350 kPa (76.5 – 83.5 kg/cm
2, 1088 – 1187 psi) CAUTION:
Be sure not to close gauge valve for longer than 10 sec-
onds.

ENGINE GENERAL INFORMATION AND DIAGNOSIS (H27 ENGINE) 6-1-13
STEP 2. DIAGNOSTIC TROUBLE CODE (DTC)/FREEZE FRAME DATA CHECK
First, check DTC, referring to “DIAGNOSTIC TROUBLE CODE CHECK” in this section. If DTC is indicated,
record DTC and freeze frame data.
After that clear DTC referring to “DIAGNOSTIC TROUBLE CODE CLEARANCE” in this section. DTC indicates
malfunction that occurred in the system but does not indicate whether it exists now or it occurred in the past and
the normal condition has been restored now. To check which case applies, check the symptom in question
according to Step 5 and recheck DTC according to Step 6, 7.
Attempt to diagnose a trouble based on DTC in this step only or failure to clear the DTC (including pending DTC)
in this step will lead to incorrect diagnosis, trouble diagnosis of a normal circuit or difficulty in troubleshooting.
STEP 3. and 4. VISUAL INSPECTION
Be sure to perform visual check of the following items that support proper function of the engine.
STEP 5. TROUBLE SYMPTOM CONFIRMATION
Based on information obtained in Step 1 “CUSTOMER COMPLAINT ANALYSIS” and Step 2 “DTC/FREEZE
FRAME DATA CHECK”, confirm trouble symptoms. Also, reconfirm DTC according to “DTC CONFIRMATION
PROCEDURE” described in each “DTC FLOW TABLE”.NOTE:
For A/T vehicle, if only DTC P0705, P0715, P0720, P0741, P0743, P0751, P0753, P0756, P0758, or P1875
is indicated in this step, proceed to “DIAGNOSIS” in SECTION 7B1.
