|APPLICABILITY:||2010-14MY Legacy and Outback Models with Panasonic Display Audio Units|
|SUBJECT:||“Check Device” Error Message Displayed|
This Service Information bulletin provides recommendations to address a customer concern of a “Check Device” error message being displayed on the screen of their Panasonic audio unit. This condition is most likely to occur in warm climates and / or during the summer months when cabin temperatures can easily exceed 158°(F) during a hot soak situation. In these extreme temperatures, the circuit inside the audio unit which supplies output voltage to the USB port reduces it from 5 volts to 3 volts or less. After connecting a device (e.g. Smartphone or MP3 player) to the USB connector requiring 5 volts, another circuit inside the audio unit determines this lower output voltage is abnormal and in turn, displays the “Check Device” message. The affected Panasonic audio units are illustrated below.
