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

When the electrical key transmitter sub-assembly is in the vehicle and the power switch is pressed, the power management control ECU receives a signal and changes the power source mode. In addition, when the shift lever is in P and the brake pedal is depressed, the hybrid control system can be started by pressing the power switch.

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.
