IMMOBILIZER SYSTEM 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.


Warning buzzer is operating.
(With antitheft system)

Immobilizer control unit (ICU); For
Electronic Control Engine (6VE1,
C24SE, 4JH1-TC, 4JA1-TC)
Immobilizer control unit (ICU) permits engine starting,
when the security code which compares the securit
y
code registered into the transponder (key) and the
security code registered into ICU, and is similarl
y
registered into ICU and engine control unit (ECM) is
compared and it is judged that it is normal. When the
code registered into the key is unusual, and when not
recognizing a security code, ICU does not permit
starting of engine.
