2007 ISUZU KB P190 engine

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.

DTC B0008
Description
When the ignition switch is ON, the ICU begins
authentication of the transponder key in the steering
lock through the antenna coil. Once the ICU transmits a
signal, the transponder must send back a specific
response signal. If the ICU receives a wrong response
signal from the transponder, this DTC will set.
Condition for Running the DTC • The ignition switch is ON.
Condition for Setting the DTC • The ICU receives a wrong response signal from the transponder key. Action Taken When the DTC Sets
• The engine will not start 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.

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.
