Operating process
The BCM activates emergency hazard warning lamp operation when receiving emergency braking
flasher ON signal from the ESP/ABS.
When the emergency stop signal is input through the P-CAN, the hazard warning lamp flashes with the
frequency of 4 Hz and the internal buzzer sounds at 1.25 Hz.
P-CAN signal during operation: Emergency Stop=EBL_INFO=0*0=Hazard Warning Lamp unrequested

24. IMMOBILIZER SYSTEM
1) System Description
The BCM without SKM communicates with the transponder in the REKES key and immobilizer unit in
the key box through wireless communication. The immobilizer unit and BCM check the encrypted codes
received through hard wire communication to start the engine.
Stays on: Communication failure between immobilizer and EMS (ECU)
Flashes: Immobilizer coding failure (once per second)
2) System Diagram

3) Immobilizer Ignition Key Verification
When turning the ignition key to the ON position, the power is supplied to the immobilizer unit and EMS
(ECU). The ECU communicates with the immobilizer unit to verify the key and transponder. If it is valid,
the ECU starts to control the engine or immobilizer indicator (illumination or flashing) when the ignition key
is turned to the START position.
Once the key is verified, valid key verification time is provided for 10 seconds and the engine can be
started by turning the ignition key to the engine START position during this verification time. If the ignition
key is turned to the START position again after the 10 seconds of verification time, the key verification
should be reperformed.
When the ignition key is inserted, the immobilizer unit requests the transponder verification through
the antenna.
The transponder sends the encrypted message to the immobilizer control unit.
The immobilizer unit compares the encrypted message received from the transponder to the
coded value through the logic circuit. If they are identical, it requests the transponder approval.
When the ignition is turned ON, the EMS (ECU) requests immobilizer verification process through
the P-CAN.
The immobilizer control unit sends the encrypted message to the EMS (ECU).
The EMS controls the engine normally when the coded value and the encrypted message sent
from the immobilizer are identical. 1.

When the immobilizer verification has failed, the verification signal is sent again 3 times for 2
seconds, and the verification procedure is carried out up to 3 times by turning the ignition ON within
10 seconds. If the three re-verifications fail, verification procedure is stopped and will be restarted
after 10 seconds.
