|---|---|---|
| 1 | B-CAN state | This diagnosis checks whether the audio unit is receiving B-CAN data properly. If the B-CAN state shows NG, check for B-CAN DTCs with the HDS. If no DTCs are detected, check for continuity in the B-CAN lines between the audio unit, the MICU, and the gauge control module. |
