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.

Ignition key reminder operation
The door LOCK switch is in LOCK position after the driver door is opened with the ignition key
inserted.
The UNLOCK signal is output for 0.5 seconds (T2) immediately after the LOCK signal output. A.
B. Operation 1.
The door LOCK switch is in LOCK position within 0.5 seconds (T1) after the door is closed with the
ignition key inserted.
The UNLOCK signal is output for 0.5 seconds (T2) immediately after the LOCK signal output. C.
D. Operation 2.
The door LOCK switch is in LOCK position after the driver door is opened with the ignition key
inserted.
The door UNLOCK signal is not output when the ignition key is removed during the door LOCK
output. E.
F. Operation 3.
