INJURY OR IMPROPER OPERATION OF THE
SUPPLEMENTAL RESTRAINT SYSTEM (SRS).
THE SRS CONTROL UNIT MOUNTING BRACKET
BOLTS MUST BE CAREFULLY TORQUED TO
ASSURE PROPER OPERATION. NEVER POWER
UP THE SRS WHEN THE SRS CONTROL UNIT IS
NOT RIGIDLY ATTACHED TO THE VEHICLE. THE
SRS CONTROL UNIT COULD BE ACTIVATED
WHEN POWERED WHILE NOT RIGIDLY
ATTACHED TO THE VEHICLE WHICH COULD
CAUSE DEPLOYMENT AND RESULT IN
PERSONAL INJURY.
WARNING: PROPER OPERATION OF THE SRS
CONTROL UNIT REQUIRES THE SRS CONTROL
UNIT TO BE RIGIDLY ATTACHED TO THE
VEHICLE STRUCTURE AND THAT THE ARROW
ON THE SENSOR BE POINTING TOWARD THE
FRONT OF THE VEHICLE.
The SRS control unit is specifically calibrated and is
keyed to the SRS control unit location SRS wiring
harness. Caution should be used to ensure prope
r
location of the SRS control unit. The keying of the
SRS control unit to its location and wiring harness
connectors should never be modified in the field.

11A-28 IMMOBILIZER CONTROL SYSTEM (4JK1/4JJ1/HFV6)
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.
• Use a scan tool to clear the DTC.
Diagnostic Aids • If the transponder key or ICU is transferred (swapped) from another vehicle, this DTC will set.

11A-34 IMMOBILIZER CONTROL SYSTEM (4JK1/4JJ1/HFV6)
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.

IMMOBILIZER CONTROL SYSTEM (4JK1/4JJ1/HFV6) 11A-37
• Stage 6 = 80 minutes (1 hour 20 minutes)
• Stage 7 = 160 minutes (2 hours 40 minutes)
• Stage 8 = 320 minutes (5 hours 20 minutes)
• Stage 9 = 640 minutes (10 hours 40 minutes)
• Stage 10 = 1280 minutes (21 hours 20 minutes)
Notice: The ignition switch must be kept at ON position
during the wait time period.
Transponder Key
Normally two or three transponder keys are provided
with a vehicle when new. Maximum five transponder
key can be provided by additional programming if
owner requests additional key(s).
Notice: During programming of the new transponder
key(s), an authentication code is programmed into the
transponder chip and it cannot be reprogrammed
again. Once this programming has been performed, the
transponder keys cannot be installed in any other
vehicle.
Notice: Keep away another key, another transponder
key, key number plate or other metal items from the
transponder key that is going to program. Otherwise,
transponder key(s) programming may be failed.
Transponder Key Erasing Procedure must be done
whenever the following condition is met:
• Owner lost transponder key(s)
Notice: If an owner lost transponder key, currently
programmed transponder key(s) information must be
erased from an ICU memory to avoid vehicle theft.
Because information on all key(s) is erased at the same
time by this procedure, reprogram remaining key(s)
and/or program new key(s).
Transponder Key Programming Procedure must be
done whenever any of the following conditions are met:
• Diagnostic chart instructs you to replace transponder key(s) • Diagnostic chart instructs you to program
transponder key(s)
• Transponder keys are erased and to do reprogramming
• Owner requests additional key(s)
ICU Resetting Procedure must be done whenever
any of the following conditions are met:
• Diagnostic chart instructs you to replace ICU
• ICU replacement without spare parts
Notice: When an ICU has been installed into a vehicle,
it must be security linked to the ECM/ PIM using the
programming procedure. Once this linking has been
performed, the ICU cannot be installed in any other
vehicle, unless the security linking between both
modules have been reset using the resetting procedure
in an ORIGINAL vehicle before transferring (swapping)
to the complaint vehicle.
ICU Programming Procedure must be done
whenever any of the following conditions are met:
• Diagnostic chart instructs you to program ICU
• New ICU is installed
• ICU is reused that was reset in an original vehicle
ECM Resetting Procedure must be done whenever
any of the following conditions are met:
• Diagnostic chart instructs you to replace ECM
• ECM replacement without spare parts
Notice: When an ECM has been installed into a
vehicle, it must be security linked to the ICU/ PIM using
the programming procedure. Once this linking has
been performed, the ECM cannot be installed in any
other vehicle, unless the security linking between both
modules have been reset using the resetting procedure
in an ORIGINAL vehicle before transferring (swapping)
to the complaint vehicle.
ECM Programming Procedure must be done
whenever any of the following conditions are met:
• Diagnostic chart instructs you to program ECM
• New ECM is installed
• ECM is reused that was reset in an original vehicle
PIM Resetting Procedure must be done whenever
any of the following conditions are met:
• Diagnostic chart instructs you to replace PIM
• PIM replacement without spare parts
Notice: When a PIM has been installed into a vehicle, it
must be security linked to the ICU/ ECM using the
programming procedure. Once this linking has been
performed, the PIM cannot be installed in any other
vehicle, unless the security linking between both
modules have been reset using the resetting procedure
in an ORIGINAL vehicle before transferring (swapping)
to the complaint vehicle.
