DA Unit
This diagnosis checks for problems in the audio-navigation unit. When you start this diagnosis, the audio-navigation unit may freeze or delay up to a minute while the diagnosis runs.
- If the icon (A) NG, replace the audio-navigation unit .
- Model: Displays the vehicle's model name.
- Program Version: Displays program number of the audio-navigation unit.
- Serial Number: Displays the audio-navigation unit serial number. That should be the same as the serial number found on the upper side of the audio-navigation unit.
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.
B-CAN
NOTE: This diagnosis must have the engine running.
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 is 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.
NOTE: When the item is a variation equipment, the item shows NG (yellow icon), and it is not reflected in diagnosis.
USB

|
| ILL | B-CAN lines |
|
| ILL CANCEL | B-CAN lines |
|
| ILL STEP | B-CAN lines | With the parking lights on, use the dashlights brightness control knob to dim and brighten the gauge. The value changes from 1 (max low) to 22 (max high). |
| Speed | B-CAN lines | This item indicates the vehicle speed (km/h). |
| PARK-VIDEO | PARKING BRAKE SW line |
|
| PARK | B-CAN lines |
|
| Current received VIN | B-CAN lines | This item indicates the VIN that received from the PCM. |
| Initial registered VIN | B-CAN lines | This item indicates the initial registration VIN that is saved in the audio-navigation unit. |
| Last registered VIN | B-CAN lines | This item indicates the additional registration VIN when the audio-navigation unit is substituted into another vehicle, or when a PCM is substituted or replaced into this vehicle. |
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 .
If you select the Transmitter Volume Change icon, the transmitter volume can be selected from three selections (Large, Middle, Small).
BT/Wi-Fi
This diagnosis allows you to independently test the Bluetooth ® module and the Wi-Fi module. The Bluetooth ® module and the Wi-Fi module are built into the audio panel. If NG, replace the audio panel unit .
Hard Key
This diagnosis checks the audio-navigation unit face switches, the audio remote switch, and the HFL switch.
To complete the test, press each buttons. As each function is tested, the corresponding button on the display should highlight.
- If any button of the audio-navigation unit does not respond, replace the audio panel or the audio-navigation unit .
- If any button of the audio remote switch does not respond, do the audio remote switch test .
- If any button of the HFL switch does not respond, do the HFL switch test .
