Power Source Mode does not Change to ON (ACC) [12/2013 - ]: Description

If the power switch is pressed with the electrical key transmitter sub-assembly in the cabin, the power management control ECU receives a signal and changes the power source mode.

HINT: 

When the cable is disconnected and reconnected to the negative (-) auxiliary battery terminal, the power source mode returns to the state it was in before the cable was disconnected.
