ENGINE IMMOBILIZER

GENERAL INFORMATION

Description

The vehicle is equipped with engine immobilizer system. The anti-theft features of the vehicle have improved
due to the integration technology of ignition key identification and engine start-up. When the engine is started
with unprogrammed ignition key, the engine immobilizer sends the detected signal to the engine control
module and the engine control module outputs the prohibit starting command, thus effectively reduces the
possibility of being stolen.

Operation

When the ignition key is inserted into the ignition switch, the immobilizer coil can detect the data information of
the ignition key, and sends the data information to the immobilizer control module. The immobilizer control
module communicates with the engine control module (ECM) via CAN - Line, realizing codes verification and
mutual certification. The ignition switch supply power to the immobilizer control module continuously, allowing
the immobilizer to save the trigger memory that has been generated and the malfunctioning content.
