SKM performs the authentication process for the SMART key and sends the engine start request to

EMS if there is a normally coded SMART key when pressing the Engine Start/Stop button with the
brake pedal depressed and gear shift lever in “P” or “N” position.

SKM sends the start request signal to PCAN network and the cranking request to BCAN network by
“SMART key location” signal when receiving the engine start signal by Engine Start/Stop

button.

SKM turns off the IGN2/ACC relay during cranking to shut down the electric loads.

SKM receives the starting status signal from EMS throug PCAN.
After cranking, SKM turns on the ACC/IGN2 relay and sends the power status signal of “IGN
after started” through BCAN.

EMS starts to crank the engine after checking the pre-heating condition if it receives the engine

cranking request 1 when pressing the Engine Start/Stop button. EMS starts to crank the engine

immediately if it receives the engine cranking request 2 when pressing the Engine Start/Stop button.
