Checking and Adjusting for
Compressor Replacement
150 cc (5.0 fl.oz.) of oil is charged in compressor (service
parts). So it is necessary to drain the proper amount of oil
from the new compressor.
1. Perform oil return operation.
2. Discharge and recover the refrigerant and remove the
compressor.
3. Drain the compressor oil and measure the extracted
oil.
4. Check the compressor oil for contamination.
5. Adjust the oil level as required.

(Draining amount of oil
from new compressor)

fl.oz)90 cc (3.0 fl.oz)
6. Evacuate, charge and perform the oil return
operation.
7. Check the system operation.
Contamination of Compressor Oil
Unlike engine oil, no cleaning agent is added to the
compressor oil. Even if the compressor runs for a long
period of time (approximately one season), the oil never
becomes contaminated as long as there is nothing wrong
with the compressor or its method of use.
Inspect the extracted oil for any of the following
conditions:

The capacity of the oil has increased.

The oil has changed to red.

Foreign substances, metal powder, etc., are present
in the oil.
If any of these conditions exists, the compressor oil
is contaminated. Whenever contaminated
compressor oil is discovered, the receiver/drier must
be replaced.
Oil Return Operation
There is close affinity between the oil and the refrigerant.
During normal operation, part of the oil recirculates with
the refrigerant in the system. When checking the amount
of oil in the system, or replacing any component of the
system, the compressor must be run in advance for oil
return operation. The procedure is as follows:
1. Open all the doors and the engine hood.
2. Start the engine and air conditioning switch to ªONº
and set the fan control knob at its highest position.
3. Run the compressor for more than 20 minutes
between 800 and 1,000 rpm in order to operate the
system.
4. Stop the engine.
Replacement of Component Parts
When replacing the system component parts, supply the
following amount of oil to the component parts to be
installed.

installed)

Evaporator 50 cc (1.7 fl. oz.)

Radiator
The radiator is a tube type with corrugated fins. In order to
raise the boiling point of the coolant, the radiator is fitted
with a cap in which the valve is operated at 88.2 ~ 117.6
kPa (12.8 ~ 17.0 psi) pressure. (No oil cooler provided for

Antifreeze Solution

Relation between the mixing ratio and freezing
temperature of the EC varies with the ratio of
anti±freeze solution in water. Proper mixing ratio can
be determined by referring to the chart. Supplemental
inhibitors or additives claiming to increase cooling
capability that have not been specifically approved by
Isuzu are not recommended for addition to the cooling
system.

7A±5 AUTOMATIC TRANSMISSION (4L30±E)
Normal Operation Of 2002 4L30±E
Transmission
Torque Converter Clutch (Electronically
Controlled Capacity Clutch : ECCC)
Application Conditions:
The clutch apply is controlled by moving the converter
clutch control valve by commanding Torque Converter
Clutch (TCC) solenoid using the PWM signal.
The TCC is normally applied in 2nd, 3rd and 4th gears
only when all of the following conditions exist:
Ð The engine coolant temperature is above 70
C
(158
F) and ATF temperature is above 18
C
(64.5
F).
Ð The shift pattern requests TCC apply.
Moreover, TCC is always applied in 2nd, 3rd and 4th
gears when the transmission oil temperature is above
135
C (275
F).
This mode should be canceled at 125
C (257
F).
ATF Warning Lamp
The ATF warning lamp will be constantly on (not flashing)
if the transmission oil temperature is above 145
C
(293
F).
The ATF warning lamp goes off again when the
transmission oil temperature is below 125
C (257
F).
Reverse Lock Out
With the selector lever in reverse position, the PCM will
not close the PWM solenoid until the vehicle is below 11
km/h (6.8 mph), thus preventing reverse engagement
above this speed.
Diagnosis
Introduction
The systematic troubleshooting information covered by
this Section offers a practical and systematic approach to
diagnosing 4L30±E transmission, using information that
can be obtained from road tests, electrical diagnosis, oil
pressure checks or noise evaluation.
The key to correcting a complaint is to make use of all of
the available symptoms and logically letting them direct
you to the cause.
When dealing with automatic transmission complaints, it
is best to gather as many symptoms as possible before
making the decision to remove the transmission from the
vehicle.
Frequently, the correction of the complaint does not
require removal of the transmission from the vehicle.
Driver Information
To analyze the problem fill out a complete description of
the owner's complaint.
Please draw a circle around the right information and
complete the following form. (The next page is an
example of a completed form). You can draw a circle
around many numbers if you are not sure.

TRANSMISSION CONTROL SYSTEM (4L30±E)
Shift Control
The transmission gear is shifted according to the shift
pattern selected by the driver. In shifting gears, the gear
ratio is controlled by the ON/ OFF signal using the shift
solenoid A and the shift solenoid B.
Band Apply Control
The band apply is controlled when in the 3±2 downshift
(engine overrun prevention) and the garage shift (shock
control).
The band apply solenoid is controlled by the signal from
the Pulse Width Modulation (PWM) to regulate the flow of
the oil.
Torque Converter Clutch Control
(Electronically Controlled Capacity Clutch
= ECCC)
The clutch apply is controlled by moving the converter
clutch valve by commanding Torque Converter Clutch
(TCC) solenoid using the PWM signal.
Line Pressure Control
The throttle signal allows the current signal to be sent to
the force motor. After receiving the current signal, the
force motor activates the pressure regulator valve to
regulate the line pressure.
On±Board Diagnostic System
Several malfunction displays can be stored in the
Powertrain Control Module (PCM) memory, and read out
of it afterward.
The serial data lines, which are required for the testing of
the final assembly and the coupling to other electronic
modules, can be regulated by this function.
Fail Safe Mechanism
If there is a problem in the transmission system, the PCM
will go into a ªbackupº mode.
The vehicle can still be driven, but the driver must use the
select lever to shift gears.
Torque Management Control
The transmission control side sends the absolute spark
advance signal to the engine control side while the
transmission is being shifted. This controls the engine
spark timing in compliance with the vehicle running
condition to reduce the shocks caused by the change of
speed.
ATF Warning Control
The oil temperature sensor detects the ATF oil
temperature to control the oil temperature warning, TCC,
and the winter mode.
Reverse Lock Out Control
With the selector lever in reverse position, the PCM will
not close the PWM solenoid until the vehicle is below 11
km/h (6.8 mph), thus preventing reverse engagement
above this speed.
Downhill Control
This mode is automatically activated from ªNORMALº
mode only when downhill conditions are recognized.
The shift pattern is identical to ªNORMALº mode except
3-4 and 4-3 shift lines at low throttle modified to get engine
braking on a larger speed range.
ECCC lines unchanged compared to ªNORMALº mode.
Uphill Control
When Uphill condition are recognized the 2-3 and 3-4 shift
and TCC apply take place only when the engine torque is
sufficient in order to avoid shift hunting.
