TROUBLE DIAGNOSIS
Revision: 2007 April2007 M35/M45
Low-pressure Side Sometimes Becomes Negative
Low-pressure Side Becomes Negative
DIAGNOSIS PROCEDURE FOR INSUFFICIENT COOLING
SYMPTOM: Insufficient cooling
1. CHECK POWER SUPPLY FOR ECV (ELECTRONIC CONTROL VALVE)
1. Disconnect compressor (ECV) connector.
2. Turn ignition switch ON.
3. Check voltage between compressor (ECV) harness connector
F34 terminal 2 and ground.
OK or NG
OK >> GO TO 2.
NG >> Check power supply circuit and 10A fuse [No. 12, 
located in the fuse block (J/B)]. Refer to PG-114, "
FUSE 
BLOCK - JUNCTION BOX (J/B)" .
If fuse is OK, check harness for open circuit. Repair or replace if necessary.
If fuse is NG, check harness for short circuit and replace fuse.
Gauge indication Refrigerant cycle Probable cause Corrective action
Low-pressure side sometimes 
becomes negative.
Air conditioning system 
does not function and does 
not cyclically cool the com-
partment air.
The system constantly func-
tions for a certain period of 
time after compressor is 
stopped and restarted.Refrigerant does not dis-
charge cyclically.
↓
Moisture is frozen at expan-
sion valve outlet and inlet.
↓
Water is mixed with refriger-
ant.
Drain water from refrigerant 
or replace refrigerant.
Replace liquid tank.
AC354A
Gauge indication Refrigerant cycle Probable cause Corrective action
Low-pressure side becomes nega-
tive.
Liquid tank or front/rear side of 
expansion valve’s pipe is 
frosted or wet with dew.High-pressure side is closed 
and refrigerant does not flow.
↓
Expansion valve or liquid tank 
is frosted.Leave the system at rest until 
no frost is present. Start it 
again to check whether or not 
the malfunction is caused by 
water or foreign particles.
If water is the cause, initially 
cooling is okay. Then the 
water freezes causing a 
blockage. Drain water from 
refrigerant or replace refrig-
erant.
If due to foreign particles, 
remove expansion valve 
and remove the particles 
with dry and compressed air 
(not shop air).
If either of the above meth-
ods cannot correct the mal-
function, replace expansion 
valve.
Replace liquid tank.
Check lubricant for contami-
nation.
