Properly trained technicians have the equipment, tools, safety instructions, and know-how to do the job correctly and safely. If a condition is described, DO NOT assume that this Service Bulletin applies to your vehicle, or that your vehicle will have that condition.

Press the “TUNE/SCROLL” button six times while pressing the “HOME” button. 1. SERVICE INSPECTION: a. CONNECTION i. On Service Menu, press “Connection” to display the list of items. 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. Affected models and head units are: • 2017-18MY Impreza (MID, HIGH) • 2018MY Crosstrek (MID, HIGH) • 2018MY Legacy/Outback (MID, HIGH) New firmware was released during late 2017 to enhance connectivity for Auxiliary Terminal part numbers: 86257FL00A and 86257FL101 (MID, HIGH). NOTE: The BASE model utilizes a different Auxilliary Terminal part number which is not affected. How to determine if the Auxiliary Terminal is pre- or post-countermeasure (CM): • CAREFULLY peel off the QR code / part number label. • Check the Lot# as shown below. If the number is after “7411” it is post-CM. Continued...
