System Diagnostic Mode: B-Can

This diagnosis checks whether the audio-navigation unit is receiving B-CAN data properly.

B-CAN (Body Controller Area Network) passes information between processors on the network. The B-CAN network uses a communication protocol that transmits data at 125 Kbps.

• This diagnosis must have the engine running.
• If any icon colors red, check for B-CAN DTCs with the HDS.
