Today have I contiune the work.
It is a Omron relay between the fuse box and the ABS unit controlling the two 12v positive supply.
I tried temp. Cables from the battery and down to the ubs unit, and the alarm disapear...
I checked the controll power to the relay, when switch off 0v and switch on 12v...
So it must be the relay or the connection in/out from it...
Why have it been installed relay? Looks like it has happend after the car was new, because some cable extension has been used....
Shall I just remove the relay? Or get it working?

Proper way to do it would be to fix the original fault...but just fitting a new relay is likely to be much easier!

I have installed a new relay now, not the same type so some rewiring.
No fault any longer
Why is it a relay, to avoid abs pump can drain the battery when parked?

Well fixed!!
More likely there is a break in the wire, or a fault on the fuse box, if it works, I would leave it, you could spend lots of time and money chasing the fault - at least with the knowledge you have gained, you will know where to look if it develops the fault again.
