Engine does not Start [08/2014 - ]: Description

When the electrical key transmitter sub-assembly is in the cabin 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.
