Network Message Chart: Acc
To enter ACC mode, with the correct IA key inside the vehicle, press and release the start/stop switch one time without pressing the brake pedal. Once the BCM receives the message from the RFA module that the correct IA key is present inside the vehicle and the BCM has detected the start/stop switch input without the BPP input, the BCM activates the internal RUN/ACC bus and internal RUN/ACC relay. The BCM also sends the ignition mode message to the other modules over the MS-CAN and the HS-CAN .
Once the ignition has entered ACC mode, the message center displays, PRESS BRAKE TO START and then ACCESSORY POWER ACTIVE.
