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.

IMMOBILIZER SYSTEM (C24SE, 4JA1-T) 11A-3
General Description
The immobilizer system consists of the four major
components which are Engine Control Module (ECM),
Immobilizer Control Unit (lCU), transponder, and scan
tool (Tech-2).
This system can be activated by a correctly programmed
transponder and starter switch is set to OFF.
This system can be deactivated by a correctl
y
programmed transponder key connected with a correctly
programmed ECM and a correctly programmed lCU.
While the system is on :

The starter cut off relay deactivates function of starter,
and the fuel injector power source is deactivated also.
• Check Engine lamp is flashing.
• W arning buzzer is operating.
