TRANSMISSION CONTROL SYSTEM (AW30–40LE) 7A2-23
Diagnostic Trouble Codes
The purpose of the “Diagnostic Trouble Codes” mode is
to display stored TCM trouble codes.
W hen “Diagnostic Trouble Codes” is selected an
“Application Menu” screen appears.
Read DTC Information
W hen “Read DTC Information” is selected, an
“Application Menu” appears with a list of DTC
information function keys addressing DTC specifics and
their origins.
Function key selections may vary for particular vehicle
and/or system.
Requested emission-related DTCs
Clear DTC Information
The purpose of the “Clear DTC Information” mode is to
command the clearing of stored TCM trouble codes.
W hen “Clear DTC Information” is selected, a “Clea
r
DTC Information”, warning screen appears. This screen
informs you that by cleaning DTC's, “all stored DTC
information in controller will be erased”.
Do you want to clear DTC's (Yes/No).
Press either the Yes or No key when answering.
After clearing codes, confirm system operation by test-
driving the vehicle.
Allow the vehicle to shift through all four forward gears
in a manner which attempts to repeat the failure
condition.
NOTE: W hen the trouble has not been repaired and
the trouble code cannot be erased, check the vehicle
again.
Data Display
The purpose of the “Data Display” mode is to
continuously monitor data parameters.
The current actual values of all important sensors and
signals in the system are displayed through F1 mode.
W hen “Data Display” is selected an “Application Menu”
appears. “Transmission Data Display”.
See “Transmission Data” on next page.
Snapshot
W hen “Snapshot” is selected an “Application Menu”
appears.
W hen “Transmission Snapshot” application is selected
from the “Application Menu”, a “Snapshot Menu”
appears, displaying several options. “Snapshot” options
may vary from one system to another.
“Snapshot” allows a recording of all vehicle parameters.
There parameters may then be replayed at a future
point in time.

This action allows you to focus on making the condition
occur, rather than trying to view all of the data in
anticipation of the fault. The snapshot will collect
parameter information around a trigger point that you
select.
W hen a snapshot is taken, it is recorded onto the
PCMCIA memory card. W hen the Tech 2 is powered
down. Snapshots are not lost.
Actuator Test
The purpose of “Actuator Test” mode is to check fo
r
correct operation of electronic system actuators.
Solenoid 2-3 Test, Solenoid 1-2/3-4 and Test TCC
Solenoid Test
You can operate the solenoids by pressing the “ON”
and “OFF” buttons.
Preconditions: P–N position, no vehicle speed, no
engine speed
Pressure Control Solenoid (PCS)
You can set desired PCS Current using the “ON” and
“OFF” button. The PCS Data informs about PCS
Current, Pressure and Duty Cycle.
Preconditions: P–N position, no engine speed, no
vehicle speed
3rd Start Lamp Test, Power Lamp Test, AT Oil
Temperature Lamp Test and Check Light Test
You can operate the lamps by pressing the “ON” and
“OFF” buttons.
Preconditions: none
NOTE: Freeze Frame
Freeze Frame is an element of the Diagnostic
Management System which stores various vehicle
information at the moment an emission-related fault
is stored in memory and when the Check Trans
Lamp is commanded on. These data can help to
identity the cause of a fault. Refer to Storing An
d
Erasing Freeze Frame Data for more detaile

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.

• 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.
