Isuzu KB P190. Manual - part 1471

IMMOBILIZER CONTROL SYSTEM (4JK1/4JJ1/HFV6) 11A-33

DTC B0013

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 response signal
that was previously erased transponder key, this DTC
will set.

Condition for Running the DTC

• The ignition switch is ON.

Condition for Setting the DTC

• The ICU detects a previously erased transponder

key.

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

• This DTC is caused by a transponder key that was

previously erased by some reason.

DTC B0014

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
receives a wrong request signal from the ECM, this
DTC will set.

Condition for Running the DTC

• The ignition switch is ON.

Condition for Setting the DTC

• The ICU detects a wrong 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

• Non-programmed ECM may set this DTC.

• If the ECM is transferred (swapped) from another

vehicle, this DTC will set.

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.

Resetting and Programming

Resetting and Programming Guidelines

Notice: The security information must be programmed
when the ICU, ECM, PIM or transponder key(s) is
replaced, or transponder key(s) is added.

Vehicle Security Information Card (If issued)

When performing ICU, ECM, PIM or transponder key(s)
resetting or programming functions using a scan tool,
you will be prompted to enter four digits of security
code (1). This information is found on the vehicle
security information card issued with the vehicle when
new. If the card is unavailable, contact a distributor’s
service department to obtain the relevant security code.
For new owners, distributor or dealership must provide
vehicle security information card that has identification
numbers of owner’s vehicle immobilizer system. This
information is very important in case of repair or
transponder key is lost. It is necessary to provide
following items in your responsibility.

• Vehicle security information card to a new owner.

• Blank vehicle security information card it is for

reissue.

• Instruction to your dealership how to use it.

Your organization must keep security code for all
vehicles as confidential data. In case of vehicle security
information card is lost, the data can be requested from
a distributor’s service department. This request will only
be processed if accompanied by the enclosed form and
proof of ownership. Once the data is received, it can be
entered in a blank card and given to the customer. The
unused card should be destroyed. Instructions on filling
out the Data Request Vehicle Security Information Card
as follows.

• The data requested under items 1 to 10 must be

provided completely, including the authorized
dealership number, the vehicle identification
number (VIN) and engine type/ number.

• Complete the form by entering data and signature/

authorized dealership stamp and send it along with
proof of ownership to address provided in the form.

• The requested data will be sent by fax to

dealership that made the request after your
organization has confirmed that the information is
correct.

Security Code

The security code is required when performing ICU,
ECM, PIM or transponder key(s) resetting or
programming functions. When a scan tool requests the
security code to be entered, and an incorrect code is
entered, the ICU, ECM or PIM will go into a security
wait time stage. This wait time stage will prevent any
further attempts to enter the security code until the wait
time has elapsed. Should a second incorrect security
code be entered after the initial wait time has elapsed,
the ICU, ECM or PIM will go into a second wait time
stage. The wait time will increase each time an
incorrect code is entered. When the correct code is
entered the wait time will rest back to its original value
of 10 seconds.

• Stage 1 = 10 seconds

• Stage 2 = 10 seconds

• Stage 3 = 10 minutes

• Stage 4 = 20 minutes

• Stage 5 = 40 minutes
