QUICKLY CHECKING OF REFRIGERANT
CHARGE (IF EQUIPPED WITH SIGHT GLASS)
CHARGE OF REFRIGERANT
The following procedure can be used for quickly checking whether
the A / C system has a proper charge of refrigerant or not.
Run engine at fast idle, and operate A / C at its max. cooling capacity
for a few minutes. Then, look at the sight glass (1) on receiver / dryer
(2) and compare what is observed with the symptoms listed in
ªCHECKING REFRIGERANT CHARGEº table given below.
CHECKING REFRIGERANT CHARGE
CONDITIONPOSSIBLE CAUSESCORRECTION
Bubbles observed in sight glassInsufficient charge of refrigerant in
systemCheck system for leaks with a leak
tester.
No bubbles observed in sight glassNo charge or proper or too much
charge of refrigerant in systemRefer to the following item.
No temperature difference
between compressor inlet and
outletEmpty or nearly empty systemRecovery, evacuate and charge
system and then check it for leaks
with a leak tester.
Noticeable temperature difference
between compressor inlet and
outletProper or too much charge of
refrigerant in systemRefer to the following item.
When A / C is turned OFF,
refrigerant in sight glass clears
immediately and remains clearToo much charge of refrigerant in
systemDischarge excess charge of
refrigerant to adjust it to a specified
charge.
When A / C is turned OFF,
refrigerant in sight glass once
produces bubbles and then clearsProper charge of refrigerant in
systemNo correction needed because
charge of refrigerant is normal.

DTC 15 (DTC C1015) ± G SENSOR CIRCUIT (FOR 4WD MODEL ONLY)
DESCRIPTION
While a vehicle is at stop or running, if the potential difference between the sensor signal terminal ªA14º and the
sensor ground terminal ªA4º is not within the specified voltage value, or if the signal voltage while at a stop does
not vary from that while running, this DTC is set.
Therefore, this DTC may be set when a vehicle is lifted up and its wheel(s) is turned. In such case, clear the DTC
and check again.

DTC 45 (DTC C1045 / C1046) ± LEFT-FRONT SOLENOID CIRCUIT
DTC 56 (DTC C1055 / C1056) ± REAR SOLENOID CIRCUIT
DESCRIPTION
The ABS control module monitors the voltage of the terminal of the solenoid circuit constantly with the ignition
switch turned ON. It sets this DTC when the terminal voltage does not become low / high for the ON / OFF command
to the solenoid or the voltage difference between solenoid circuit terminals exceeds the specified value with the
solenoid turned OFF.
INSPECTION
STEPACTIONYESNO
11) Check solenoid referring to item
ªABS HYDRAULIC UNIT OPERATION CHECKº
in this section.
Is it in good condition?Check terminals ªA11º
and ªA27º connection.
If connections OK,
substitute a known-
good ABS hydraulic
unit / control module
assembly and
recheck.Go to step 2.
21) Ignition switch OFF.
2) Disconnect ABS hydraulic unit / control module
connector. (See Fig. 1)
3) Check for proper connection to ABS hydraulic
unit / control module connector at terminal ªA11º.
4) If OK, then measure voltage between terminal
ªA11º of module connector and body ground.
Is it 10 ± 14 V?Substitute a known-
good ABS hydraulic
unit / control module
assembly and
recheck.ªW / Blº circuit open.
