Power Source Mode does not Change to ON (IG and ACC) [08/2015 - 08/2019]: Description

When the key is in the vehicle and the engine switch is pressed, the power management control ECU receives a signal and changes the power source mode.

HINT: 

• When the power management control ECU 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 mode returns to the mode it was in before the battery cable was disconnected.
