Hello all,

I'm currently in a process of finding and replacing injector #3 as it got short circuit (error code: ECM-P1263 - Cylinder 3 High to Low side short circuit)

Could you please shed a light what the codes on top of the injector actually mean and what I should be aware of when replacing it?
(I noticed that the last line (KJ25) is the same for all four injectors)

Also (but secondly) what is this green ring around high pressure line of injector #3?
It exist only in this one.
