PRINTED-HEATER CHECK
1. Run engine at 2,000 r/min. Check heater element with
battery at full.
2. Turn ON rear window defogger switch. Measure heater
element voltage with circuit tester at rear window glass
centre A.
Condition is good if it indicates about 6V.
3. If 12 V is indicated at A, there is a break in the negative
terminals from A.
Move test bar slowly to negative terminal to detect where
voltage changes suddenly (0V).
4. If 0 V is indicated at A, there is a break in the positive
terminals from A. Defect where the voltage changes
suddenly (12 V) in the same method described above.

REFRIGERANT CHARGING
Caution
The refrigerant generates toxic gases when it is expored
to a heat source such as fire. Keep flames away from
the refrigerant. Perform refrigerant charging at a
well-ventilated place.

Gas charging set case [No. EA101CS-2]

Gauge manifold [No. EA101N-1]

Charging valve [No. EA108N]

Adapter valve [No. EA104AD-3]
NOTE
The adapter valve opens when the handle is turned
clockwise and closes when it is turned counter-clockwise.

Quick joint (for low pressure) [No. EA413L]

Quick joint (for high pressure) [No. EA413H]

Charging hose (red) [No. EA104N-1]

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 PROCEDURE FOR TROUBLE SYMPTOMS
Inspection procedure 1
Communication with the MUT-II is not possible.Probable cause
If communication with all other systems is not possible, there is a high
possibility that there is a malfunction of the diagnosis line. If communication
with only the A/C is not possible, the cause is probably a malfunction of the
diagnosis line or of the A/C-ECU power supply system (earth).
Malfunction of connector or harness

Malfunction of A/C-ECU

other system possible?NOCheck the MUT-II diagnosis line, and
repair if necessary.
