REMOVAL SERVICE POINTS
ADRIVE BELT REMOVAL
1. Align the hole in the auto-tensioner bracket with that in
the arm and insert a screwdriver into the holes.
2. Remove the drive belt.
BSUCTION HOSE, DISCHARGE HOSE
DISCONNECTION
Plug the disconnected hose and the compressor nipple not
to let foreign matter get into them.
Caution
Seal the hoses completely, otherwise the compressor
oil and receiver will absorb water vapour easily.
CCOMPRESSOR REMOVAL
When doing this work, be careful not to spill the compressor
oil.

INSTALLATION SERVICE POINT
ACOMPRESSOR INSTALLATION
If a new compressor is installed, first adjust the amount of
oil according to the procedures described below, and then
install the compressor.
1. Measure the amount (X m
) of oil within the removed
compressor.
2. Drain (from the new compressor) the amount of oil
calculated according to the following formula, and then
install the new compressor.
New compressor oil amount
120 to 140 m
– X m
= Y m

NOTE
(1)“120 to 140 ml” is the amount of oil filled in a new
compressor.
(2) Y m
indicates the amount of oil in the refrigerant
line, the condenser, the cooling unit etc.
INSPECTION
REFRIGERANT-TEMPERATURE SWITCH SIMPLE
CHECK
When the A/C is off, check that there is continuity between
the refrigerant-temperature switch terminals. If no, replace
the compressor assembly.
COMPRESSOR MAGNETIC CLUTCH OPERATION
INSPECTION
Connect the battery (+) terminal to the compressor side
terminal, and earth the battery (–) terminal to the body of
the compressor. The condition is normal if the sound of the
magnetic clutch (click) can be heard.AView A

BSNAP RING INSTALLATION
Install the snap ring using a pair of snap ring pliers so that
the tapered surface is at the outer side.
CARMATURE INSTALLATION
Align the serration projection of the crankshaft with the notch
in the armature, and then fit them together.
DSELF-LOCKING NUT INSTALLATION
Use the special tool to hold the magnet clutch, and tighten
the self-locking nut in the same manner as removal.
EAIR GAP ADJUSTMENT
Check whether or not the air gap of the clutch is within the
standard value. If there is a deviation of the air gap from
the standard value, make the necessary adjustment by
adjusting the number of shims.

INSPECTION PROCEDURES FOR DIAGNOSIS CODES
Code No.11 Inside air temperature sensor system (open
circuit)Probable cause
This diagnosis code is output if the power supply line or input line of the inside
air temperature sensor inside A/C-ECU is open-circuited and no signal is input
from the inside air temperature sensor to A/C-ECU.
Malfunction of the A/C-ECU
Replace the A/C-ECU.
Code No.12 Inside air temperature sensor system (short
circuit)Probable cause
This diagnosis code is output if the power supply line or input line of the inside
air temperature sensor inside A/C-ECU is short-circuited and inside air
temperature sensor power supply voltage signals are input to A/C-ECU.
Malfunction of the A/C-ECU
Replace the A/C-ECU.
