REFRIGERANT LEVEL TEST

M1552008400594

Use the refrigerant recovery station to remove all of the refrig-
erant, and then calculate the amount of the refrigerant and 
charge it.

A/C COMPRESSOR CLUTCH TEST

M1552019900128

1. Disconnect the A/C compressor clutch connector to the A/C 

compressor clutch.

2. Connect positive battery voltage directly to the connector for 

the A/C compressor clutch.

3. Supply a ground to the A/C compressor assembly.
4. If the A/C compressor clutch is normal, there will be a "click." 

If the pulley and armature do not make contact ("no click"), 
there is a malfunction.

SIMPLE INSPECTION OF THE A/C PRESSURE 
SENSOR

M1552014700464

1. Assemble a gauge manifold on the high pressure service 

valve.

2. Disconnect the A/C pressure sensor connector and connect 

special tool test harness MB991658 as shown in the illustra-
tion.

3. Turn ON the engine and then turn ON the air conditioner 

switch.

4. At this time, check to see that the voltage of A/C pressure 

sensor terminal No. 2 reflects the specifications of the fig-
ure.
NOTE: The allowance shall be defined as 

±

5%.

COMPRESSOR DRIVE BELT ADJUSTMENT

CHARGING 

M1552001200663

Use the refrigerant recovery station to charge the refrigerant.

METHOD BY USING REFRIGERANT RECOVERY 
AND RECYCLING UNIT

Using the refrigerant recovery and recycling unit, refill the 
refrigerant.
NOTE: Refer to the Refrigerant Recovery and Recycling Unit’s 
Instruction Manual for operation of the unit.

DISCHARGING SYSTEM

Use the refrigerant recovery unit to discharge refrigerant gas 
from the system.
NOTE: Refer to the Refrigerant Recovery and Recycling Unit’s 
Instruction Manual for operation of the unit.

REFILLING OF OIL IN THE A/C SYSTEM

Too little oil will provide inadequate compressor lubrication and 
cause a compressor failure. Too much oil will increase dis-
charge air temperature.
When a compressor is installed at the factory, it contains 140 
cm

3

 (4.7 fl.oz) of refrigerant oil. While the A/C system is in 

operation, the oil is carried through the entire system by the 
refrigerant. Some of this oil will be trapped and retained in vari-
ous parts of the system.
When the following system components are changed, it is nec-
essary to add oil to the system to replace the oil being removed 
with the component.
