DIAGNOSIS SYSTEM
HINT:
- When system self-diagnosis DTCs cannot be output due to a malfunction that is preventing diagnosis mode from being started or the multi-display from displaying, read the DTCs using the GTS.
-
Even if navigation system turns off IG depending on setting of radio and display receiver assembly, it has started in a background. Therefore I perform setting confirmation of radio and display receiver assembly before checking it.
