Push Button Start System: Off

The BCM controls the relays providing voltage to the vehicle electrical systems. When the ignition is in the ON mode, a single press and release of the START/STOP button changes the ignition to the OFF mode. No programmed key is required to change the ignition to the OFF mode when the vehicle is running.

If the vehicle is in motion, a momentary press of the START/STOP button does not shut the vehicle off. If the vehicle is moving, the START/STOP button must be pressed and held for longer than one second to turn the ignition off.

When the ignition switch turns off, the BCM deactivates the ignition relay and communicates the state of the ignition to the other modules by sending a message over the CAN.
