What might be the problem with my indicator lights when locking/unlocking the car? Before, when i lock the car indicator lights flashed but now for a few weeks they do not. I know that there is a feature to enable with key code but how could the car itself turned this feature off. Are there any relays or fuses about this? I checked the fuses and they are OK

you need to get this function re-enabled (switched on) using examiner equipment/software however to do this you need the access code (key code) which you might have to apply/buy depending what country you live in.

I am wondering what is the reason to have it disabled by itself
