DESCRIPTION
When the engine switch is pushed with the electrical key in the cabin, the power management control ECU receives signals to change the power source mode.
HINT:
To allow use of the Techstream to inspect the push-button start function when the power source mode is off, repeat opening and closing any of the doors. Opening and closing a door establishes communication between the Techstream and the power management control ECU. (Opening and closing a door can also be simulated by operating a door courtesy light switch.)
