Engine does not Start: Description

When the electrical key transmitter sub-assembly 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*1 and the brake pedal*1 or clutch pedal*2 is depressed, the engine can be started by pressing the engine switch.
