B-CAN System Link
B-CAN System Link
This diagnosis tests 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.
If any icons are red, check for B-CAN DTCs with the HDS. If no DTC is detected, check for B-CAN bus line between the audio-navigation unit and the failure unit(s).
