Looks like it all goes through the Smart Entrance Control Unit.
Have a look in the service manual. Electrical, Lighting, Page LT-96

So after a lot of searching finally made it.
I had a problem with the interior light that didnt light when i unlocked the car,Everything seemed to be ok about fuses,relays e.t.c.
A friend from here said something about probably problem of smart entrance control,so started checking it,went to nissan service and after measurements said "Yes thats the problem its the smart entrance control,changing it would cost 450 Euros"
-Come again????????? i said....

After hours of googling tried something risky but yes it worked.

so...

Remove the negative pole from the baterry before you begin anything
remove the plastics under the steering column to find the smart entrance control (look deep up and right)(left handed)

The smart entrance control is this


Its location under the steering column (mine is left handed)


Opened and see that this one transistor R4383 is the problem



Unsolder will be hell be prepared and have patience,all the body is solder so you have to warm very well the top to be removed first unsolder the two legs and then the body

Tried to find the same transistor r4383.......No luck at all,luckilly as we had a discussion with the seller at the electonic store he proposed this Buz 90 http://www.datasheetcatalog.com/datasheets_pdf/B/U/Z/9/BUZ90.shtml,Has the same behaviour and specifications as the r 4383 but one little problem its Bigger.


So with the help of dremel


Became like this


Be carefull while you soldering that one needs skills my friends,if you cant do it go to a electronic repair shop to do it for you

We do not solder the center leg of the transistor just cut it.Dont forget to solder the top

close it


put it back on.Everything works like a charm Interior lightning and the ring that lights to the ignition,you will notice only that when you unlock the car the signal lights flashes a bit faster.

Thanks to some russian sites for primera and nissan generally
Thats all from me dudes
Hope somebody will find this helpfull

P.S If the administrators wants they can make it also DIY.

Excellent workClap
 
The transistor is easier to remove if you cut the 2 legs first.

of course my friend you have my full permission,the purpose we are here here is to share our love for our primeras and to help each other instead of going to nissan service and give them half a monthly payment for something we could fix ourselfs.by the way the transistor cost 2,5 euros,and they were looking for 450 eurosDead

Hi - I'm well impressed you worked out which the faulty component was.  I've got a problem with the rear demister on my P12.  Apparently this is also on the SECU board.  Any advice on how I could trace the faulty component?  Nissan wanted nearly £400 in the UK to replace the whole unit!

There is a hole in the faulty transistor.
You would need to find which component terminal 31 (applies ground to demist relay) goes to on the board.
I would guess one of the other 2 similar looking transistors.

Hi,

I know this is an old topic, but i now have the interior lamps staying on permanently so I am looking at doing this fix.

Could anyone confirm that this is the correct product to use?

I have ordered the part. £3.75 inc postage! Bargain. It is coming from America about the beginning of April, so I'll keep you all posted on the progress, thanks.

UPDATE :-

Ok so the transistor arrived yestrday from America and to be really honest, IT'S TINY!!! like at first I thought they'd forgot to put it in the padded bag.  So the chances of me soldering it are, at best slim.  However, not to be beaten, I approached my mother in law who works for an electronics company for advice.

In minutes the new transistor was expertly soldered to the board and i rushed home to refit the SECU to the car.  I'm really happy to report it worked, with no nasty side effects found as yet, needless to say i'm thrilled to pieces with the repair and the expert info supplied in these forums!

Many thanks to Tsakimak for the 'How to' it is invaluable, cheers ClapHug
