Engine does not Start [10/2015 - ]: Description

When the key is in the vehicle and the engine switch is pressed, the certification ECU (smart key ECU assembly) receives a signal and changes the power source mode. In addition, when the shift lever is in P or N and the brake pedal is depressed, the engine can be started by pressing the engine switch.

HINT:

When the certification ECU (smart key ECU assembly) is replaced with a new one and the cable is connected to the negative (-) battery terminal, the power source mode changes to on (IG).
When the battery cable is disconnected and reconnected, the power source returns to the mode it was in before the battery cable was disconnected.
