Power Source Mode does not Change to ON (READY): Description

When the electronic key is in the cabin and the power switch is pressed, the power management control ECU receives a signal and changes the power source mode. In addition, when the power switch is pressed with park (P) selected and the brake pedal depressed, the hybrid system turns on (READY).

HINT: 

• When the power management control ECU is replaced with a new one and the cable is connected to the negative (-) auxiliary battery terminal, the power source mode changes to on (IG).
• When the auxiliary battery cable is disconnected and reconnected, the power source returns to the mode it was in before the auxiliary battery cable was disconnected.
