Network Message Chart: 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.
