Service Precaution

WARNING: THIS VEHICLE HAS A SUPPLEMENTAL RESTRAINT SYSTEM (SRS). REFER TO THE SRS

COMPONENT AND WIRING LOCATION VIEW IN ORDER TO DETERMINE WHETHER YOU ARE PERFORMING

SERVICE ON OR NEAR THE SRS COMPONENTS OR THE SRS WIRING. WHEN YOU A RE PERFORMING

SERVICE ON OR NEAR THE SRS COMPONENTS OR THE SRS WIRING, REFER TO THE SRS SERVICE

INFORMATION. FAILURE TO FOLLOW WARNINGS COULD RESULT IN POSSIBLE AIR BAG DEPLOYMENT,

PERSONAL INJURY, OR OTHERWISE UNNEEDED SRS SYSTEM REPAIRS.

CAUTION: Always use the correct fastener in the proper location. When you replace a fastener, use ONLY the

exact part number for that application. HOLDEN will call out those fasteners that require a replacement after

removal. HOLDEN will also call out the fasteners that require thread lockers or thread sealant. UNLESS

OTHERWISE SPECIFIED, do not use supplemental coatings (Paints, greases, or other corrosion inhibitors) on

threaded fasteners or fastener joint interfaces. Generally, such coatings adversely affect the fastener torque

and the joint clamping force, and may damage the fastener. When you install fasteners, use the correct

tightening sequence and specifications. Following these instructions can help you avoid damage to parts and

systems.

General Description

The AW30-40LE is a 4–speed fully automatic transmission. It uses a microcomputer as a control unit to judge running

conditions including throttle opening rate and vehicle speed, then it sets the shifting point in the optimum timing so that

best driving performance can be achieved.

In addition, the built–in shift mode select function can select three shift modes according to the driver's preference:

• Normal mode –Normal shift pattern.

• 3rd Start mode –Starts in 3rd gear to reduce slippage on ice or snow.

• Power mode has a delayed up shift when more powerful acceleration is required.

Also, the built–in fail–safe function (“backup mode") assures driving performance even if the vehicle speed sensor,

throttle signal or any solenoid fails.

Further, the self–diagnostic function conducts diagnosis in a short time when the control system fails, thus improving

serviceability.

The major features of AW30-40LE are as follows:

• A compact structure consisting of 2 sets of planetary gears and flat torque converter.

• Electronic control selects the optimum shift mode according to the driving conditions.

• Electronic control maintains the optimum hydraulic pressure for clutch, band brake as well as transmission so that

shift feeling is improved.

• Two sets of planetary gears reduce friction of power train.

Also, a lockup mechanism in the torque converter reduces fuel consumption.

• Wide gear ratio and high torque rate of torque converter provide excellent starting performance.

Control and Functions

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 S1 and the shift solenoid S2.

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

The clutch application is controlled by the TCM via the

Torque Converter Clutch (TCC) solenoid.

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

Transmission Control Module (TCM) 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

TCM will go into a “backup" 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 3rd start mode.

Reverse Lock Out Control

With the selector lever in reverse position, the TCM will

not close the PWM solenoid until the vehicle is below 15

km/h (9.3 mph), thus preventing reverse engagement

above this speed.

Downhill Control

This mode is automatically activated from NORMAL

mode only when downhill conditions are recognised.

The shift pattern is identical to NORMAL mode except

3-4 and 4-3 shift lines at low throttle modified to get

engine braking on a larger speed range.

Uphill Control

When uphill condition are recognised the 2-3 and 3-4

shift and TCC apply are down only when the engine

torque is sufficient in order to avoid shift hunting.

The mode become normal drive mode when the 3rd

start switch is operated from ON to OFF.

Comparison of mode

1. The normal drive mode is set at the normal shift

points.

2. The shift points of the power drive mode are shifted

to the higher speed side, compared to the normal

drive mode.

3. The 3rd start mode is a special mode used

exclusively for starting in third gear.

3rd start Mode

1. The 3rd start switch will operate when switched on

after all of the following conditions are present:

a. The gear select position is “D" range only.

b. Vehicle speed is 11 km/h (7 mph) or less.

c. Transmission oil temperature is 120°C (248°F)

or less.

d. Accelerator opening is at 8% or less.

2. Cancel Release

1. Cancellation by driver

a. Turning off the 3rd start mode switch

b. Shifting select position to “3", “2", or “L" (3rd

start mode is not cancelled by selecting “N",

“R", or “P" )

c. Ignition key is turned off.

2. Automatic cancellation

a. When vehicle runs at 34 km/h (21mph) or

more for 1 second or more

b. When transmission oil temperature reaches

120°C (284°F) or above

NOTE: The mode returns to normal drive mode or

power drive mode after the 3rd start mode is cancelled.

Backup Mode

If a major system failure occurs which could affect

safety or damage the transmission under normal

vehicle operation, the diagnostic system detects the

fault and overrides the Transmission Control Module

(TCM).

The “CHECK TRANS" light flashes to alert the driver,

and the transmission must be manually shifted as

follows:

Shifts are firmer to prevent clutch slip and consequent

wear. The fault should be corrected as soon as

possible.

CAN bus systems in automatic

transmission control (AW30-40LE)

The automatic transmission control system in AW30-

40LE uses high speed CAN bus system .The individual

CAN bus systems are connected via two interfaces and

can exchange information and data. This allows control

modules that are connected to different CAN bus

systems to communicate.

High speed CAN bus

Transmission control modules in the vehicle that require

continuous, rapid communication are connected to the

high speed CAN bus. For example, the automatic

transmission is continuously notified of the current

engine load status. Since the automatic transmission

control module has to react immediately to load status

changes, rapid communication is required between the

engine control module and the automatic transmission

control module. The high speed CAN bus in the AW30-

40LE is designed as a two-wire CAN bus (twisted pair).

The wires are shielded and twisted. The transfer rate is

500 K baud.

Clear DTC

NOTE: If you clear the DTC (Diagnostic Trouble

Codes) you will not be able to read any codes recorded

during the last occurrence.

NOTE: To use the DTC again to identify a problem,

you will need to reproduce the fault or the problem.

This may require a new test drive or just turning the

ignition on (this depends on the nature of the fault).

1. IF you have a Tech 2:

1. Connect the Tech 2 if it is still not connected go

through Tech 2 OBD CONNECTION.

2. Push “F1: Clear DTC Information" in the

Application Menu and answer “Yes" to the

question “Do you want to clear DTC's?"

a. When a malfunction still exists and the Tech

2 displays “AW30-40 CODES NOT

CLEARED". This means that the problem is

still there or that the recovery was not done.

Please go to DTC CHECK.

b. When a malfunction has been repaired and

the recovery is done the Tech 2 displays

“AW30-40LE CODES CLEARED".

2.When you have no Tech 2, the stored trouble codes

can be cleared by shorting the terminals No.11 and

No.4 or 5 (ground) of data link connector with a lead

wire for 1  6 seconds.

DTC Check

1. Diagnostic Trouble Codes (DTC) have been

identified by Tech 2.

2. You have written the list of the DTCs. The order of

the malfunctions has no meanings for this TCM.

Usually only one or two malfunctions should be set

for a given problem.

3. Check directly the DTCs you identified. The DTCs

are sorted by number. Refer to Diagnostic Trouble

Code (DTC) Identification in this section.

TCM Precaution

The TCM can be damaged by:

1. The electrostatic discharge

2. The short circuit of some terminals to voltage or to

ground.

Electrostatic Discharge Damage Description:

1. Electronic components used to control systems

are often designed to carry very low voltage, and

are very susceptible to damage caused b

electrostatic discharge. It is possible for less than

100 volts of static electricity to cause damage to

some electronic components. By comparison, it

takes as much as 4,000 volts for a pers on to even

feel the zap of a static discharge.

2. There are several ways for a person to become

statically charged. The most common methods o

charging are by friction and induction. An exam ple

of charging by friction is a person sliding across a

car seat, in which a charge of as much as 25,000

volts can build up. Charging by induction occurs

when a person with well insulated shoes stands

near a highly charged object and momentaril

touches ground. Charges f or the sam e polarity are

drained of f, leaving the person highly charged with

the opposite polarity. Static charges of either type

can cause damage, therefore, it is important to use

care when handling and testing electronic

components.

NOTE: To prevent possible electrostatic discharge

damage:

1. Do not touch the TCM connector pins or soldered

components on the TCM circuit board.

2. Be sure to follow the guidelines listed below if

servicing any of these electronic components:

3. Do not open the replacement part package until it is

time to install the part.

4. Avoid touching electrical terminals of the part.

5. Before removing the part from its package, ground

the package to a known good ground on the

vehicle.

lways touch a known good ground before handling

the part. This step should be repeated before

installing the part if the part has been handled while

sliding across the seat, while sitting down from a

standing position or while walking some distance.

Information On TCM

1. The Transmission Control Module (TCM) is located

in the place of a clutch pedal and is the control

centre of the electronic transmission control system.

2. The TCM must be maintained at a temperature

below 85°C (185°F) at all times. This is most

essential if the vehicle is put through a paint baking

process. The TCM will become inoperative if its

temperature exceeds 85°C (185°F). Therefore, it is

recommended that the TCM be removed or that

temporary insulation be placed around the TCM

during the time the vehicle is in a paint oven or other

high temperature process.

3. The TCM is designed to process the various inputs

and then respond by sending the appropriate

electrical signals to control transmission upshift,

downshift, shift feel and torque converter clutch

engagement.

4. The TCM constantly interprets information from the

various sensors, and controls the systems that

affect transmission and vehicle performance. By

analysing operational problems, the TCM is able to

perform a diagnostic function by displaying DTC(s)

and aid the technician in making repairs.

DTC P0722 (FLASH CODE 11) Output Speed Sensor Signal Error

RTW37AMF000501

Circuit Description

Vehicle speed information is provided to the TCM by the

output revolution sensor. This sensor is located in the

transmission adapter housing.

The output revolution sensor is an electromagnetic

pulse pickup type that generates a speed signal

according to the revolution of the transmission output

shaft. As a result, the sensor sends a sine wave signal

(AC) to the TCM, which converts this sine wave signal

(pulse voltage) to a RPM signal.

Condition for setting the DTC

The TCM detects following conditions at 500 times

continuously.

(When gear positions are 1st, 2nd and 3rd.)

When the TCM detects following conditions at the same

time.

• Output speed signal is no pulse while input speed

signal are 45 pulses.

(Detection time, 1st: 0.031 sec, 2nd: 0.057 sec, 3rd:

0.087 sec, at vehicle speed is 38 mph.)

Action Taken When The DTC Sets

• The TCM uses input speed sensor as a vehicle

speed.

• No squat control.

• No engine torque control.

• No line pressure control.

• No use 4th gear.

• No lock-up control.

• No slope control.

• Check Trans ON.

• DTC stored.

• No reverse lockout control.

Conditions For Clearing The DTC

• The DTC can be cleared from the TCM history by

using a scan tool.

• The DTC will be cleared from history when the

vehicle has achieved 40 warm-up cycles without a

failure reported.

• After more than 1 second has elapsed after the

ignition key has been turned “ON", short between

No.11 and No.4 (ground) of DLC (Data Link

Connector). Then, after 1 second, but within 6

seconds, discontinue shorting.

Diagnostic Aids

• Inspect the wiring for poor electrical connection at the

TCM. Look for possible bent, backed out, deformed

or damaged terminals. Check for weak terminal

tension as well. Also check for a chafed wire that

could short to bare metal or other wiring.

Inspect for a broken wire inside the insulation.

• When diagnosing for a possible intermittent short or

open condition, move the wiring harness while

observing test equipment for a change.

• Check output speed sensor for proper mounting and

adjustment.

DTC P1767 (FLASH CODE 67) ECM CAN Invalid

RTW37AMF000401

Circuit Description

The automatic transmission control system in AW30-

40LE uses high speed CAN bus system. The individual

CAN bus systems are connected via two interfaces and

can exchange information and data. This allows control

modules that are connected to different CAN bus

systems to communicate. Transmission control

modules in the vehicle that require continuous, rapid

communication are connected to the high speed CAN

bus. The automatic transmission is continuously notified

of the current engine load status. Since the automatic

transmission control module has to react immediately to

load status changes, rapid communication is required

between the engine control module and the automatic

transmission control module. The high speed CAN bus

in the AW30-40LE is designed as a two-wire CAN bus

(twisted pair). The wires are shielded and twisted. The

transmission rate is 500K band.

Condition for setting the DTC

When the TCM can not detect all RAM from following

steps in initialising routine.

Action Taken The DTC Sets

• Check Trans ON.

• DTC stored.

Conditions For Clearing The DTC

• The DTC can be cleared from the TCM history by

using a scan tool.

• The DTC will be cleared from history when the

vehicle has achieved 40 warm-up cycles without a

failure reported.

• After more than 1 second has elapsed after the

ignition key has been turned “ON", short between

No.11 and No.4 (ground) of DLC (Data Link

Connector). Then, after 1 second, but within 6

seconds, discontinue shorting.

Diagnostic Aids

• Inspect the wiring for poor electrical connection at the

TCM. Look for possible bent, backed out, deformed

or damaged terminals. Check for weak terminal

tension as well. Also check for a chafed wire that

could short to bare metal or other wiring. Inspect for a

broken wire inside the insulation.

• When diagnosing for a possible intermittent short or

open condition, move the wiring harness while

observing test equipment for a change.

DTC U2104 (FLASH CODE 65) CAN BUS OFF

RTW37AMF000401

Circuit Description

The automatic transmission control system in AW30-

40LE uses high speed CAN bus system. The individual

CAN bus systems are connected via two interfaces and

can exchange information and data. This allows control

modules that are connected to different CAN bus

systems to communicate. Transmission control

modules in the vehicle that require continuous, rapid

communication are connected to the high speed CAN

bus. The automatic transmission is continuously notified

of the current engine load status. Since the automatic

transmission control module has to react immediately to

load status changes, rapid communication is required

between the engine control module and the automatic

transmission control module. The high speed CAN bus

in the AW30-40LE is designed as a two-wire CAN bus

(twisted pair). The wires are shielded and twisted. The

transmission rate is 500K band.

Condition for setting the DTC

The TCM detects CAN BUS OFF for 0.18 sec (After the

TCM leaves a communication start with the ECM for

0.64 sec) continuously..

Action Taken When The DTC Sets

• The throttle pressure is max.

• The TCM judges APS(Accelerator Position Sensor)

angle is 0% at the time of shift operation.

• No throttle pressure reduction.

• No torque reduction.

• No lock-up control.

• No slope control.

• No squat control.

• Check Trans ON.

• DTC stored.

• Engine REV is 7000 rpm.

• Coolant temperature is 80°C.

• No detect DTC P1767.

• No detect DTC P0560.

• No detect DTC P0712, 0713.

Conditions For Clearing The DTC

• The DTC can be cleared from the TCM history by

using a scan tool.

• The DTC will be cleared from history when the

vehicle has achieved 40 warm-up cycles without a

failure reported.

• After more than 1 second has elapsed after the

ignition key has been turned “ON", short between

No.11 and No.4 (ground) of DLC (Data Link

Connector). Then, after 1 second, but within 6

seconds, discontinue shorting.

Diagnostic Aids

• Inspect the wiring for poor electrical connection at the

TCM. Look for possible bent, backed out, deformed

or damaged terminals. Check for weak terminal

tension as well. Also check for a chafed wire that

could short to bare metal or other wiring. Inspect for a

broken wire inside the insulation.

• When diagnosing for a possible intermittent short or

open condition, move the wiring harness while

observing test equipment for a change.

• Inspect the wiring for EMI (Electro-Magnetic

Interference). Check that all wires are properly routed

away from coil, and generator. Also check for

improperly installed electrical options. When this test

is performed, turn “OFF" on electronic auto parts

switches to improperly for a noise preventing.
