REFRIGERANT PIPES AND HOSES
INSPECTION
1) Use a leak tester to check hoses and pipes for any gas leakage.
2) 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 system when reinstal-
ling.
2) Replace defective hose or pipe.
CAUTION:
As soon as the above hose or pipe is disconnected, cap
its opened fitting to prevent moisture and dust from en-
tering.
INSTALLATION
1) Reverse removal procedure to install refrigerant line.
2) Evacuate and charge system. Refer to ªEVACUATINGº and
ªCHARGINGº in this section.
INSPECTION OF IDLE SPEED WITH A / C ON
For G16 and J20 engines model, refer to Section 6E1.
For H25 engine model, refer to Section 6E2.

COMPRESSOR ASSEMBLY
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 1B-2.
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.
PRECAUTION
When servicing the compressor, keep dirt or foreign material away from getting on or into the compressor 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 ªOn-vehicleº 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 Trichloroethane, 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 dis-
carded and new refrigerant oil added to the compressor.
Minor repair procedures may be done on the vehicle without discharging the system. Major repair procedures re-
quire that the system be discharged of refrigerant.
INSPECTION
1) Install manifold gauge set (1) as shown in the figure.
2) Close Hi (4) and Lo (5) hand valves.
3) Run engine at fast idle.
4) Check compressor assembly for following items.
If any of the above checks indicated a defect, repair compressor
assembly.

High pressure gauge reading is not low and low pressure
gauge reading is not higher than normal.

Metallic sound.

Leakage from shaft seal.

DTC 57 (DTC C1057) ± SOLENOID AND PUMP MOTOR POWER SOURCE
CIRCUIT
DESCRIPTION
The ABS control module monitors the voltage at terminal ( ªA11º and ªA27º) of the fail-safe and pump motor relays
circuit constantly with the ignition switch turned ON. When all solenoid circuit voltages are below the specified value
or the voltage at the terminal ªA27º became below the specified value while the pump motor is operating, this DTC
will be set. As soon as the voltage rises to the specified level, the set DTC will be cleared.

2) Disconnect ABS hydraulic unit / control module
connector. (See Fig. 1)
3) Check proper connection to ABS hydraulic unit /

4) If OK, then measure voltage between connector
terminal ªA27º and body ground.

DTC 63 (DTC C1063) ± ABS FAIL-SAFE RELAY CIRCUIT
DESCRIPTION
The ABS control module monitors the voltage at the terminal of the solenoid circuit constantly with the ignition
switch turned ON. Also, immediately after the ignition switch is turned ªONº, perform an initial check as follows.
Switch the fail-safe relay in the order of ON
OFF
ON and check if the voltage at 6 solenoid circuit terminals
changes to High
Low
High. If anything faulty is found in the initial check and when the voltage at all solenoid
circuit terminals is low with the ignition switch turned ON and ABS not operated, this DTC will be set.
