The Smart Entrance Control Unit is not working, this device controls: central locking, interior lights, warning chimes, rear window defogger and theft warning.

I have checked fuse no.5 and it appears good/light tester says good.
I have done an ECU reset/also disconnected the battery for 30 minutes.
Nothing seems to help.

Hello, I have seen a shorted door lock actuator take out a fuse for the system, there are 5 more fuses that need to be checked for the system, here is a wiring diagram so you can see the fuses and how the system works. Please check the fuses and get back to me. Check out the images (below). Please let me know what happens.

thank you for your help.
I can have another look at my fuses.
Previously checked them and they visually looked good/not broken/blown. I tested with my fuse tester and with my volt meter tester , they were good.
Might be possible the 50A fusible link is bad.
Wondering if I should go back to the autowrecker where I located a 2006 Xtrail and remove the fusable link. Hopefully a few dollars versus the $40-50 it retails for.

update: I used my light tester and all the fuses (under the left side of the dash/under the steering wheel area) lit up.
I do not see a 50 Amp fusible link.
To add more info, my Xtrail is a gas engine 2.5 four cylinder. Left hand drive, I believe it was built in Japan.
Here is a list of things that do not work as before.
- front door courtesy lights.
-rear hatch glass defogger.
-key fob remote locking .
- power door lock switch.
- no chime warning sound when exiting the vehicle and headlights not turned off.
-all three overhead dome/cargo lights not working.
If you can show me something with pics that be great.

If you have power at the white wire at the BCM the fusible link is good. I would check that first.
