4. WITH SKM VS. WITHOUT SKM
BCM (BODY CONTROL MODULE)
BCM (Body Control Module) inputs/outputs data from various switches, sensors, and other modules
through the hard wire and CAN communication, and controls the body and electronic system of the
vehicle.
For the vehicles with SKM, the SKM unit communicates with BCM through B-CAN. It sends the door
LOCK/UNLOCK signal by smart key, theft deterrent mode signal, and passive entry signal, etc. to the
BCM to control each module. The signals for engine running and stopping controls are sent to the EMS
(ECU) through the P-CAN.
For the vehicles without SKM, the BCM receives door LOCK/UNLOCK signal by smart key, theft
deterrent mode signal, and passive entry signal, etc. directly from the modules to control them. The
BCM controls the engine running and stopping by sending the corresponding signals to the EMS (ECU)
after verifying the ignition key. The controls for other modules may vary depending on the vehicle
specifications.

10. KEY HOLE LAMP CONTROL
The key hole lamp goes out when the REKES LOCK signal is received (in theft deterrent
mode).
When the key hole lamp and immobilizer signals are received simultaneously, the immobilizer signal
overrides the key hole lamp signal.
When the immobilizer confirmation is failed, regardless of the key hole lamp operation condition, it
flashes for 11 seconds at intervals of 0.5 sec. ON/0.5 sec. OFF.
When the ignition is turned ON in virgin status, the key hole lamp flashes for 8 seconds at intervals
of 0.5 sec. ON/0.5 sec. OFF. -
