System Operation: Start
To enter START mode, with the correct IA key inside the vehicle, press and hold the brake pedal, then press and release the start/stop switch. Once the BCM receives the message from the RFA module that the correct key is present inside the vehicle and the BCM has detected the BPP input with the start/stop switch input, the BCM activates the internal RUN/START bus and the RUN/START relay. The BCM also sends the ignition mode message to the other modules over the MS-CAN and the HS-CAN.
The engine can be started from any ignition mode. Once the ignition has entered START mode, the indicator in the start/stop switch illuminates.
