TRANSMISSION CONTROL SYSTEM (AW30–40LE) 7A2-35
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.

Tech-2 Features
1. Tech-2 is a 12volt system. Do not apply 24 volts.
2.
After connecting and/or installing the vehicle
communication interface (VCI) module, PCMCI
A
card and data link connector (DLC) to the Tech-
2, connect the tool to the vehicle DLC.
3. Make sure the Tech-2 is OFF when removing o
r
installing the PCMCIA card.
4. The Tech-2 has the capability of two snapshot.
5. The PCMCIA card is sensitive to magnetism and
static electricity, so care should be taken in the
handling of the card.
6. The Tech-2 can not plot a graph when replaying
a snapshot.
7.
Always return to the Main Menu by pressing the
EXIT key several times before shutting down.
8. To clear diagnostic trouble codes (DTCs), open
Application Menu and press "Clear DTC ".

Getting Started
Before operating the Isuzu PCMCIA card with the
Tech-2, the following steps must be performed:
1. The Isuzu System PCMCIA card inserts into the
Tech-2.
2. Connect the SAE 16/19 adapter to the DLC
cable.
3. Connect the DLC cable to the Tech-2.
4. Mark sure the vehicle ignition is off.
5. Connect the Tech-2 SAE 16/19 adapter to the

IMMOBILIZER CONTROL SYSTEM (4JK1/4JJ1/HFV6) 11A-27
DTC B0007
Circuit Description
When the transponder key authentication is completed,
the ICU begins authentication of the ECM. The ECM
transmits a specific request signal to the ICU and the
ICU sends back a response signal to the ECM. Both
communication signals are carried out via a controller
area network (CAN) communication bus. If the ICU
does not detect a request signal from the ECM, this
DTC will set.
Condition for Setting the DTC • The ICU does not receive a request signal from the ECM.
Action Taken When the DTC Sets • The engine will fail to run if the fault occurs before starting the engine. Condition for Clearing the DTC
• A current DTC clears once ignition cycle has occurred without the fault recurring.
• A history DTC will clear after 50 consecutive ignition cycles, if the condition for malfunction is no
longer present.
• Use a scan tool to clear the DTC.
Diagnostic Aids • Electromagnetic interference may affect intermittent condition.
• If the ignition switch is cycled (ON > OFF > ON) rapidly, this DTC may set but engine starts. This is
normal and a current DTC clears once ignition
cycle has been normally occurred.

IMMOBILIZER CONTROL SYSTEM (4JK1/4JJ1/HFV6) 11A-35
DTC U0100
Circuit Description
When the transponder key authentication is completed,
the ICU begins authentication of the ECM. The ECM
transmits a specific request signal to the ICU and the
ICU sends back a response signal to the ECM. Both
communication signals are carried out via a controller
area network (CAN) communication bus. The ICU
monitors CAN operational status by expecting a
constant flow of messages from the ECM. If the ICU
fails to send an expected message to the ECM, this
DTC will set.
Condition for Setting the DTC • The ICU detects that the CAN Bus OFF status. Action Taken When the DTC Sets
• The engine will fail to run if the fault occurs before starting the engine.
Condition for Clearing the DTC • A current DTC clears once ignition cycle has occurred without the fault recurring.
• A history DTC will clear after 50 consecutive ignition cycles, if the condition for malfunction is no
longer present.
• Use a scan tool to clear the DTC.
Diagnostic Aids • Electromagnetic interference may affect intermittent condition.
• Any communication fault with the ECM may set this DTC.
