F-CAN

NOTE: This diagnosis must have the engine running.

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.
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.

NOTE: When the item is a variation equipment, the item shows NG (yellow icon), and it is not reflected in diagnosis.

Mic

This diagnosis allows you to test the microphone. To properly check the microphones, make sure you are sitting in the driver's seat.

NOTE: Before this diagnosis, check the response of the TALK button on the HFL switch by the Hard Key diagnosis.

Press the TALK button, and within 5 seconds in a normal voice say "testing"' toward the microphone in the roof console. The Mic Level indicator on the screen should momentarily turn green. The test is set to OK by indicating green more than 6 steps. If there is no Mic Level movement when you speak, Go to HFL does not respond troubleshooting .
