Tech Tips
Illustrations may differ from the actual vehicle screen depending on the device settings and options. Therefore, some detailed areas may not be shown exactly the same as on the actual vehicle screen.
If the system cannot enter diagnostic mode, inspect all AVC-LAN communication components and repair or replace the malfunctioning parts.
Start diagnostic mode at least 90 seconds after turning the power switch on (IG). Otherwise, some items cannot be checked.
There are 4 methods to start diagnostic mode. Start diagnostic mode by using one of them.

While pressing and holding the "MENU" switch, operate the light control switch: Off → Tail → Off → Tail → Off → Tail → Off.
Diagnostic mode will start and the "Service Menu" screen will be displayed.
Method 2:
Connect the GTS to the DLC3.
Turn the power switch on (IG).
Turn the GTS on.
Enter the following menus: Body Electrical / Navigation System / Utility / Map Information.

Since the remote touch screen may recognize a pinch in/out or flick operation if operated with 2 fingers, always use 1 finger to operate the remote touch screen in self-diagnostic mode.
Turn the power switch on (IG).
Perform a flick operation on the remote touch screen from the left to the right 5 times and then perform a flick operation from the right to left 5 times with the screen and audio turned off as shown in the illustration.
