Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Power Source Mode does not Change: Description
When the engine switch is pushed with the electrical key in the cabin, the power source control ECU receives signals to switch the power source mode.
HINT:Β
To allow use of the Techstream to inspect the push-button start function when the engine switch is off, repeat opening and closing any of the doors. Opening and closing a door establishes communication between the Techstream and the power source control ECU. (Opening and closing a door can also be duplicated by operating a door courtesy light switch.)
