F-CAN

NOTE: This diagnosis must have the vehicle is in the READY TO DRIVE mode.

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

If F-CAN shows RX ERROR, replace the audio-navigation unit - Refer to: Audio-Navigation Unit Removal and Installation (2014 2015), or Audio-Navigation Unit Removal and Installation (With Display Audio) (2017) .
If F-CAN shows TIME OUT, There is a possibility that some items are NG (red icon). When all the items from each transmitting unit is NG, check for F-CAN DTCs with the HDS. If DTCs not detected, check for continuity in the F-CAN lines between the audio-navigation unit and the transmitting unit.
