USB DEVICE DOES NOT FUNCTION (With Navigation, Without Auto Idle Stop System) (2016 2017 2018)
NOTE:
- Check the vehicle 12 volt battery condition first - Refer to:
- Check the USB's specifications:
-
- Mass-storage class ready digital audio player with USB 2.0 port
- More than 256 MB storage space
- Supports MP3, WMA, and AAC (encoded with the iTunes) files, DRM files are not supported
- Not all players and player functions work with the USB adapter. Please see the Owner's Manual for more information. Always test the customer's USB device in a known-good vehicle of the same year and trim (if possible). Technologies change and are updated frequently which may result that USB devices may work in newer vehicles, but not in older vehicles of the same model.
- Before doing this troubleshooting, check the USB Error Cords - Refer to:
Audio System Error Codes [Color Audio Type (5-inch Screen)] or
Audio System Error Codes [Display Audio Type (8-inch Screen)] (2016 2017 2018) .
- Check the connectors for poor connections or loose terminals.
12 Volt Battery Test (With Auto Idle Stop System) or
12 Volt Battery Test (Without Auto Idle Stop System) .
- Determine possible failure area (USB device, others)
-1. Connect the customer's USB device to a known-good vehicle (same year/trim) that is equipped with a USB port, and check the USB device operation.
Does the USB device working properly in the known-good vehicle?
YES
Go to step 2.
NO
See the Owner's Manual for details about the USB device requirements and approved file types.
- Problem verification
-1. On the customer's vehicle, connect the customer's USB device to each of the USB ports.
NOTE: Except the USB port D and the USB port E.
- 2. Turn the vehicle to the ON mode.
- 3. Check the USB device operation in the customer's vehicle.
Does the USB device work properly in the customer's vehicle?
YES
Intermittent failure, the system is OK at this time. Inspect the connectors of the USB device, USB port and USB adapter for wear.
NO: All USB port do not work
The failure is duplicated in all USB port, Audio-Navigation Unit Removal and Installation (2016 2017 2018) .
NO: USB port A and B do not work
The failure is duplicated in USB port A and B, go to step 3.
NO: USB port A does not work
The failure is duplicated in USB port A, go to step 8.
NO: USB port B does not work
The failure is duplicated in USB port B, go to step 9.
NO: USB port C does not work
The failure is duplicated in USB port C, replace the affected shielded harness, and recheck. If the symptom does not go away, replace the audio-navigation unit - Refer to:
- Fuse check
-1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Check the following fuse.
Fuse No. A14 (15 A) Location Under-hood fuse/relay box Is the fuse OK?
