Service Information
Isuzu single and 6-disc LLAI (Low Level Audio Interface) changers have error codes to help diagnose playback issues.
Isuzu single and 6-disc CD players may have only an ERR message and no other indicator. If an ERR message is encountered without any other identifier, you may review the following error codes to try to determine the cause of the error and correct it before sending the unit to the authorized service center. If ERR or E (and a number) appears on a customers radio display, the number may give you a clue to the problem and corrective action.
Below is a list of code numbers that may appear on the unit.
