Swipe the screen to check the next items.

This diagnosis checks whether the audio-navigation unit has received specific B-CAN data. If B-CAN shows NO ERROR, an error is not detected between the B-CAN bus and the audio-navigation unit.

If B-CAN shows RX ERROR, replace the audio-navigation unit .
If B-CAN shows TIME OUT, there is a possibility that some items are NG (red icon). When all the items from each transmitting unit are NG, check for B-CAN DTCs with the HDS. If DTCs not detected, check for continuity in the B-CAN lines between the audio-navigation unit and the transmitting unit.
