11A-24 IMMOBILIZER CONTROL SYSTEM (4JK1/4JJ1/HFV6)
DTC B0003
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 never receives a 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 does not receive a response signal from the 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 • Electromagnetic interference may affect intermittent condition.
• An antenna coil problem may set this DTC.
• Objects that block transponder key in the steering lock may set this DTC.
• Another key that is attached to the key ring may affect this DTC to set.
• If the ignition switch has been turned ON without transponder key this DTC sets.

IMMOBILIZER CONTROL SYSTEM (4JK1/4JJ1/HFV6) 11A-45
Description and Operation
Immobilizer System Description
Legend1. Transponder key
2. ICU
3. Controller area network (CAN) communication bus lines 4. Anti-theft control unit (with anti-theft system)
5. Engine control module (ECM) (4JK1/ 4JJ1)
6. Powertrain interface module (PIM)
7. Engine control module (ECM) (HFV6)

The immobilizer controls engine starting along with the
engine control module (ECM). The main system
components are the ICU, the ECM, the PIM (HFV6)
and the transponder key. The immobilizer system is
activated (immobilized) by an incorrectly programmed
or non-programmed transponder key, the ICU or the
ECM. While this system is activated, the ECM controls
the fuel injection system and starter cut relay in order to
fail to engine running. A typical engine starting
sequence is below.
1. When the ignition switch is ON, the ICU begins authentication of the transponder key in the
steering lock. The ICU transmits a specific request
signal to the transponder key and the transponder
key sends back a response signal to the ICU. Both
communication signals are carried out via antenna
coil.
2. Because the anti-theft system alarms if a key or other methods unlock the door, when the
transponder key is correctly authenticated the ICU
transmits an alarm cancel (disarm) signal to the
anti-theft control unit. (With anti-theft system)
3. After 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. 4. After the ECM authentication is completed, the
ECM enables engine running.
