gt1 head 1.jpg
This is the fuse that i replaced, there was no power going to the Diagnostic Head via the OBD port. Once i replaced this fuse the head began working again. Hope this helps
Hi.
My BMW EDIC interface a.k.a GT1 Yellow Diagnostic Head or DK-20 or DK-21 has been working this last 8 years. Suddenly it don't boot when i connect to car.
In a normal situation when i connect it to the car, led flash until boots and before it get the network ip.
Now it don't do nothing, no lights, nothing.
I read in the forum:
" The problem is the head if you open it up there are three SMD fuses labeled F1, F2 and F3 the fuse types are 391J they are very very small you can check the resistance on each fuse with an ohmeter. You have to desolder the bad fuse which is probably the F3 fuse and resolder a good fuse ie(391J) and that should fix your problem as I had the same problem and this fixed it."
