2.5.2 Description and Operation

2.5.2.1 Description and Operation

The engine anti-theft locking system can prevent the theft of the vehicle via preventing the
operation on the engine. The engine anti-theft locking system can prevent the startup of the vehicle.
If engine anti-theft locking system cannot identify the transponder code of the ignition key, the
operational functions of the engine will be prohibited. Engine anti-theft locking system and
remote anti-theft system are operated independently. Engine anti-theft locking system and remote
anti-theft system have no interaction.

Engine anti-theft system components are listed below:

–

Engine anti-theft system control module (IMMO)

–

Engine Control Module (ECM)

–

Electronic Anti-theft Coil (Engine Anti-theft System, Antennas)

–

Ignition Key (Transponder)

1. Ignition

Key

(Transponder)

It contains the microprocessor and transceiver coil. Through the magnetic field generated by EAS
Coil, it gets the energy and information from the magnetic field, and decrypts and encrypts the
information before transmitting the information back to the EAS Coil.

2. Electronic Anti-theft Coil (Engine Anti-theft System, Antennas)

EAS Coil is surround-mounted to the ignition lock core. When the ignition key is inserted into the
ignition lock core and turns the ignition switch to the “ON” position, the induced magnetic field is
generated to transfer the communication signal between the anti-theft controller and the
transponder. Integrated on the electronic anti-theft coil is a light- emitting diode controlled by the
interior lighting circuit in order to facilitate the driver to locate the ignition cylinder.

3. Engine Anti-theft System Control Module

The engine anti-theft system control module is arranged below the middle part of the dashboard;
after receiving the transponder information transmitted from the electronic anti-theft coil, the
engine anti-theft system control module compares the information with the key information read
in the memory, so as to decide whether sending fuel commissioning/forbidding command.

Note: If the anti-theft system can not get the ignition key transponder information, it will not
send any signal to the engine control module.

4. Engine Control Module

Engine control module is installed under the passenger side of instrument panel, near the
air-conditioning blower. Based on the signal received from the engine control module anti-theft
system, it sends instruction to enable / disable fuel injection.

Based on the instruction received from the engine control module anti-theft system, engine control

377

module will decide whether to send the engine control module to the body lock / unlock status
information.

Based on the instruction received from the engine control module anti-theft system, engine control
module will decide whether to send to the combination instrument the request of "Light the
engine anti-theft system warning lamp".
