replacing the control unit, please be sure to
undertake “Obtaining Information” from the ne
w
unit. W ith VIN not being programmed into the new
control unit at the time of shipment, "obtaining
information" is not complete (because the vehicle
model, engine model and model year are specified
from VIN). For the procedure get additional
information on vehicles, instruction will be provided
in dialog form, when TIS2000 is in operation.
9. Following instructions by Tech 2, push the “Exit”
switch of Tech 2, turn off the ignition of the vehicle
and turn off the power of Tech 2, thereby removing
from the vehicle.

3.Data Exchange
1. Connect Tech 2 to P/C, turn on the power and
click the “Next” button of P/C.
2. Check VIN of the vehicle and choose “Next”.
3. W hen a lack of data is asked from among the
following menu, enter accordingly.
Select following Menu
• Model Year
• Model
• Engine type
• Transmission type
• Destination code (vehicles for general export)*1
• Immobiliser
* 1: How to read the destination code
"Destination code can be read from ID Plate affixed on
vehicles, while on VIN plate the destination code is
described at the right-hand edge of Body Type line. In

TRANSMISSION CONTROL SYSTEM (AW30–40LE) 7A2-39

Diagnostic Trouble Code (DTC) Type
Definitions
Emission Related DTC
Action Taken When the DTC Sets - Type A
• The Engine Control Module (ECM) illuminates the
malfunction indicator lamp (MIL) when the
diagnostic runs and fails.
• The ECM records the operating conditions at the
time the diagnostic fails. The ECM stores this
information in the Freeze Frame/ Failure Records.

Action Taken When the DTC Sets - Type B
• The ECM illuminates the MIL on the second
consecutive driving cycle when the diagnostic runs
and fails.
• The ECM records the operating conditions at the
time the diagnostic fails, the ECM stores this
information in the Failure Records. If the
diagnostic reports a failure on the second
consecutive driving cycle, the ECM records the
operating conditions at the time of failure and
stores this information in the Freeze Frame and
updates the Failure Records.

Conditions for Clearing the MIL/ DTC - Type A o
r
Type B • The ECM turns OFF the MIL after 3 consecutive
driving cycles when the diagnostic runs and does
not fail. (Euro 4 Specification)
• The ECM turns OFF the MIL after 1 driving cycle
when the diagnostic runs and does not fail.
(Except Euro 4 Specification)
•
A current DTC clears when the diagnostic runs
and passes after 1 driving cycle.
• A history DTC clears after 40 consecutive warm-
up cycles, if no failures are reported.
• Use a scan tool to clear the MIL and the DTC.

Non-Emissions Related DTCs
Action Taken When the DTC Sets - Type C or Type
D
• The TCM illuminates the Check Trans lamp when
the diagnostic runs and fails.
• The TCM records the operating conditions at the
time the diagnostic fails. The TCM stores this
information in the Failure Records.

• The TCM illuminates the Check Trans on the
second consecutive driving cycle when the
diagnostic runs and fails.
• The TCM records the operating conditions at the
time the diagnostic fails, the TCM stores this
information in the Failure Records. If the
diagnostic reports a failure on the second
consecutive driving cycle, the TCM records the
operating conditions at the time of failure and
stores this information in the Freeze Frame and
updates the Failure Records.

Conditions for Clearing the Check Trans Lamp/ DTC
- Type C or Type D
• The TCM turns OFF the Check Trans lamp after 1
driving cycle when the diagnostic runs and does
not fail.
•
A current DTC clears when the diagnostic runs
and passes after 3 driving cycle.
• A history DTC clears after 40 consecutive warm-
up cycles, if no failures are reported.
• Use a scan tool to clear the Check Trans lamp and
the DTC.

Action Taken When the DTC Sets - Type E or Type F • The TCM will not illuminate the Check Trans lamp.
• The TCM records the operating conditions at the
time the diagnostic fails. The TCM stores this
information in the Failure Records.

Conditions for Clearing the DTC - Type E or Type F •
A current DTC clears when the diagnostic runs
and passes after 1 driving cycle.
• A history DTC clears after 40 consecutive warm-
up cycles, if no failures are reported.
• Use a scan tool to clear the DTC.

• All of the following conditions are met.
- Device Control is not operating
- Disable Normal Communication Service is receiving enable
- DTC Clear is not operating
Condition For Setting The DTC
W hen the TCM detects following conditions at 20 times
continuously.
• Ignition voltage is less than 9 volts for 1 second o
r
more continuously. (DTC P0562)
• Ignition voltage is more than 18 volts for 1 second o
r
more continuously. (DTC P0563)
Action Taken When The DTC Sets
• 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.
• W hen diagnosing for a possible intermittent short o
r
open condition, move the wiring harness while
observing test equipment for a change.
