INTRODUCTION:
This bulletin provides troubleshooting steps to follow when diagnosing customer concerns regarding USB functionality. Please start by completing the Harman Investigation Guide Questionnaire as it gathers important details which will help with diagnosis and will be required should the condition not be resolved by this troubleshooting. While completing the questionnaire, follow the question flow based on the customer concern. Answer each related question noting the results to each in detail while performing the diagnostics. Review the entire bulletin before beginning in order to understand the flow for the listed concern. If the concern you have is not listed, check the Service Manual “Infotainment (Diagnostics) – Diagnostics with Phenomena” section as a starting point.
SERVICE PROCEDURE / INFORMATION:
REMINDER: Customer satisfaction and retention starts with performing quality repairs.
1) Always confirm the condition as reported by the customer.

ii. OK: Each device is connected properly.
iii. NG: Connection is not established, or connection status (possibly including the related harness) is faulty.
NOTES:
- The USB connection showing “NG” when no USB device is connected to USB ports is normal.
- If the concern involves “CarPlay not working”, make sure a genuine Apple cable is used. In some cases, aftermarket cables may cause connection issues.
- If the concern involves “Android Auto not working”, try using another cable since Android phones do not require use of a genuine cable.
c. Do other USB devices work in the suspect vehicle? If yes, check the USB device’s operation in another like vehicle.
d. Please provide detailed information regarding the USB device (brand, device type, file system, types of files on device, etc.).
3) This section addresses issues related to Apple CarPlay and/or Android Auto not launching consistently due to poor connectivity to USB Media.
