CAN BUS
The CAN BUS version of the custom Android headunits can be very clever, too clever. They know when a door opens and can display it on their screen; the android headunits even know which door has been opened.
Useful features
The valuable features of the Android headunits CAN BUS integration to the cars computer sub-system can be critical. When fitting a bigger screen than the car was designed for, a few buttons or controls may be lost to the more prominent real estate of the screen. The Android headunit can then mirror the missing controls on its screen. This is quite common with Tesla style screens and air condition controls.
When it goes wrong
The door open signal is carried on the CAN BUS, and the clever android headunits can pick up on that call to display a message and some pretty graphics to depict a ‘door open’ on a car picture. All very useful for the driver should you need to know if the doors are open or closed. But what happens when the ‘driver’s door is open, BUT the screen shows it as the passenger door!’ you may even find it transposed the other way and get ‘Passenger door open, the screen shows it as the driver’s door!’? Not at all good to show to your friends.
The solution
As you may have already thought: It has to be in the settings somewhere!
You would be correct, but obviously, you came here looking for the solution to ‘Driver is door open, the screen shows it as the passenger door!’ because it was not easy to find in the setting screens.
Try this:
Go to settings
Go to ‘car infotainment.’
Go to About device.’
Click the settings cog by ‘HMI version.’
Enter pin 8888 (or find your PIN)
Click ‘CAN type.’
Change ‘swap f-door’ and ‘swap r-door’ from ‘normal’ to ‘swap.’
Job done!
Testing
Now to test the door opening. Try the driver’s door; see that the image of the car on the screen and its door now matches the actual door you opened and closed. Try also the passenger door in the same way. You now have a correctly configured CAN BUS and door open/closed signal with your Android headunit.
Conclusion
If the new settings described above worked correctly, then you should now have the situation where:
The right door open will be showing on the Android headunit screen.
I have exactly that issue on my android ts10 head unit but I don’t see what you mentioned above in settings. Is there anywhere else I could fix this?
Have a good look through all the menus, look for can-bus, developer etc. Failing that reach out to the vendor to ask where the CAN BUS options are located. Mention the doors are incorrectly associated.
I found it in protocol settungs used it but still got wrong
