(c) Recheck for DTCs. Based on the DTC output in the first step, try to force output of the audio system DTC by simulating the operation indicated by the DTC.

HINT
* If the system cannot enter the diagnosis mode, inspect each AVC-LAN communication signal and repair or replace problem parts.
* Even if the malfunction symptom is not confirmed, check for DTCs. This is because the system stores past DTCs.
* Check and clear past diagnostic trouble codes. Check the diagnostic trouble code and inspect the area the code indicates.
