7A2-12 TRANSMISSION CONTROL SYSTEM (AW30–40LE)
Control and Functions
Item Description
Shift and lock-up control Shift and lock-up points can be controlled in accordance with output of S1, S2, and SL solenoids based on "Shift-map" made up of vehicle speed and the opening.
Overdrive off cut control W hen the select lever is operated from D to 3, if the vehicle speed is more than 142km/h (89mph), TCM enables to remain overdrive in order to prevent over rev.
Lock-up cut control Lock-up is inhibited with following condition in order to improve the shift feeling.
• 1st gear
• Idling
• Operating brake switch
• L position
• During shift change
Driveng mode select control
• The TCM selects a suitable driving mode from the ten kinds for the variety
driving condition.
1) Normal mode
2) Power mode
3) 3rd start mode
4) HOT mode
5) L4 mode
6) Up slope1 mode
7) Up slope2 mode
8) Down slope mode
9) Auto cruise mode
10) W arm up mode • The priority of driving mode
Normal < Power < Up slope1 < Up slope2 < Down slope < L4 < W arm up < Auto
cruise < 3rd start < HOT
Oil temperature compensation
control If the ATF temperature exceeds 130
°C (266 °F), the TCM selects the HOT mode
shift pattern for lock-up, thus preventing the oil temperature from rising. (The HOT
mode is released, if the ATF temperature is less than 115 °C /239 °F.)
3rd start mode control By selecting 3rd start mode, the vehicle starting can be controls smoothly on low
frictional road like a snowy or muddy.
1. Enable condition a) The gear select position is "D" only.
b) Vehicle speed is less than 11km/h (7mph).
c) Transmission oil temperature is less than 120 °C (248 °F).
d) Accelerator opening is less than 8%.
e) Except 3rd start mode.
2. Disable condition a) Turning off the 3rd start mode switch
b) Shifting select position to "3", "2", or "L"(3rd start mode is not canceled b
y
selecting "N", "R", or "P")
c) Ignition key is turned off.
d) Vehicle speed is more than 35km/h (22mph).
L4 mode control The TCM detects whether the transfer is engaged in high or low based on L4 switch
signal, and selects the "Shift-map".

7A2-16 TRANSMISSION CONTROL SYSTEM (AW30–40LE)
CAN bus systems in automatic
transmission control (AW30-40LE)
The automatic transmission control system in AW 30-
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 module 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 AW 30-
40LE is designed as a two-wire CAN bus (twisted pair).
The wires are shielded and twisted. The transfer rate is
500 K baud.

How To Diagnose The Problem
1. To avoid incorrect diagnostics, this book needs to
be followed accurately. Unless stated, do not jump
directly to a section that could contain the
solution. Some important information may be
missed.
2. The sections in CAPITALS and bold are the main
sections that can be found in the contents.
3. The go to “SECTION” means to continue to check
going to the “section”.
4. The go through “SECTION” means to go through
the “section” and then to go back to the place the go
through was written.
5. BASIC ELECTRIC CIRCUITS:
You should understand the basic theory o
f
electricity. This includes the meaning of voltage,
amps, ohms, and what happens in a circuit with an
open or shorted wire. You should also be able to
read and understand wiring diagrams.
Check Trans Indicator
Find CHECK TRANS indicator and verify if it is
A. Flashing: Go to On-Board Diagnostic (OBD)
System Check.
B. Staying on: Go through “Check Trans” Check.
C. Is never “ON” when the ignition key is turned on: Go through “Check Trans” Check
D. Is “ON” during 3 seconds at ignition but “OFF” after: Normal operation. No DTC or malfunction.

On-Board Diagnostic (OBD) System Check
This test determines if the transmission or its input or
output connections or sensors are failing.
1. Connect the Tech 2: Go through Tech 2 Operating.
2. Turn on the ignition but not the engine.
3. Push “F0” on Tech 2 to see the Diagnostic Trouble Code (DTC):
4. Do you have a DTC? YES: write down all code numbers and do the DTC
CHECK
NO: the DTC can not help you find the problem.
1. Go through “Check Trans” Check
2. If it is flashing and the flash is 0.4 seconds “ON”
and 0.4 seconds “OFF”, this means that you
should have a DTC stored. Please recheck go
to On-Board Diagnostic (OBD) System Chec
k
and if you find the same problem, replace the
Transmission Control Module (TCM).
“Check Trans” Check
1. Indicator is “ON” during 3 seconds at ignition but it
is “OFF” after the engine starts. The indicator is
working normally go to On-Board Diagnostic
(OBD) System Check .

95 terminal 3 is shorted to ground.
4. Verify that the instrument panel terminal 8 o
f
connector B–24 is connected to battery.
5. If a problem was solved: Go to Check Trans
Indicator .
NO: Replace Transmission Control Module
(TCM).
4. Indicator is staying “OFF” with the ignition “ON”
(engine “OFF”).
1. This means that connection between the lamp
and the indicator control unit is shorted to
battery or opened.
2. Verify if instrument panel terminal 25 o
f
connector B–23 is shorted to battery or open.
3. Verify if the indicator control unit connector C–
95 terminal 3 is shorted to battery or open.
4. Verify that the instrument panel terminal 25 o
f
connector B–23 is connected to battery. If not,

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 and perform the Tech 2
Operating.
2. Push “F1: Clear DTC Information” in the
Application Menu and answer “Yes” to the
question “Do you want to clear DTC's?”
a. W hen a malfunction still exists and the Tech 2 displays “AW 30-40 CODES NOT
CLEARED”. This means that the problem is
still there or that the recovery was not done.
Please go to DTC Check.
b. W hen a malfunction has been repaired and the recovery is done the Tech 2 displays
“AW 30-40LE CODES CLEARED”.
2. W hen you have no Tech 2, the storaged trouble
codes can be cleared by shorting the terminals
No.11 and No.4 or 5 (ground) of data link connecto
r
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 o
f
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.
Self-diagnosis code (Flash code) display
• The stored trouble codes can be identified by
shorting the terminal No. 11 and No. 4 or No. 5
(ground) data link connector with a lead wire.
Indication Method:
1. Terminal No. 11 and No. 4 or No. 5 (ground) data
link connector are short circuited.
2. Turn the key switch to the ON position.
3. If no trouble code exists, the normal code (12) is
indicated repeatedly.
