      • If the system cannot enter the diagnosis mode, inspect the AVC-LAN and all the components that connect to the AVC-LAN for short circuits and repair or replace the problem part.

      • Even if the malfunction symptom is not confirmed, check for DTCs. This is because the system stores past DTCs.
