2.2 User’s manual of the Immobilizer System for Vehicle
When the ignition is turned on, the oscillator in the Immobilizer unit drives the antenna coil
to produce a 125 kHz electromagnetic field which activates the transponder.
The transponder and the Immobilizer exchange data by modulating the electromagnetic field.
An encrypted protocol is used to ensure that the exchange of data is secured.
The identity code of the transponder, which is unique for each ignition key, is transmitted to the Immobilizer
unit and forwarded to the Engine ECU
using CAN communication link.
If the transponder identity is recognized the engine is allowed to start, otherwise the engine will not start.
△ CAUTION
When ignition is turned on, do not bring metal close to transponder.
