When the BCM receives "Panic command by smart key remote control" as a BCAN signal, it
activates panic alarm by operating the horn and turn signal lamp for 30 seconds with a interval of
0.5s ON/0.5s OFF. However, the BCM used in EU region is operated when receiving the panic
command from the smart key remote control and the signal that the smart key is in the vehicle with

2. IMMOBILIZER/REMOTE CONTROL KEY CODING
1) System Overview
While the communication between BCM/SKM and ECU is based on the CAN communication, the
communication between transponder and BCM/SKM is based on LF (Low frequency) and RF (Radio
frequency). When the ignition switch is turned to ON position, the BCM checks the verified transponder
according to the immobilizer verification procedure, if correct, allows the vehicle to start the engine. The
immobilizer indicator comes on during the communication and if the verification is carried out
successfully the indicator goes off.
If there is something wrong in the system, the indicator blinks.
