Power Source Mode does not Change to ON (ACC) [03/2017 - ]: 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. Use this troubleshooting procedure when the power source mode does not change to on (ACC) but does change to on (IG).

HINT: 

When the battery cable is disconnected and reconnected, the power source mode returns to the mode it was in before the battery cable was disconnected.
