1997 XJ PCM diagram required

Good day, Sirs!

I have a problem with my wifes mostly stock (just +2inch) jeep XJ 1997.
Check engine says p0202 means that the PCM detected a fault in the injector or the wiring to the injector

I replaced wires between second injector and ASD and 2nd injector and pin15 in PCM white plug (the middle one). Nothing changed.
After that I've opened PCM. Well from pin 15 and 2nd injecotrs mosfet there is no signal. For other injectors signal from pin to mosfet is ok. Made straight wire from pin 15 to mosfet, injector started to work, but still I have p0202 error. So I need to find problem between pin15 and 2nd injectors mosfet and I need PCM Diagram.....can't google it anywhere.
So can please anyone help me with PCM Diagram pdf?
Pics of PCM if needed:

Thanks in advance! And best regards from #RussianJeepFamily =)

i would further check the traces on the circuit. it might split off and route into a sense circuit. you fixed the mosfet to the injector but may have bypassed the sensing.

Yep. But to be sure what to fix I'd better look at diagram) Coz PCM has 2 layers of soft board and they are glued to alum. case. Have to heat it to take off the case.

might be easier to replace the pcm. im not sure of a diagram for the internals of the pcm. but it sounds like you do have the injector firing. or is it shutting it back off because it cant see it working?

Well, if I were in USA, I would change the PCM with plate in roof console (coz otherwise immo will shut down engine). But I live with a big bear with balalaika in his arms, and changing PCM here on restyle Jeeps is a bit hard coz have to buy it from Byelorussia))

Well, injector is firing now (rolled over fuel ramp and turned on starter to see), but I still have check engine on board, and it might missfire sometimes or smth else and get rich fuel mix.
Sure I will change it sooner or later, but nowdays I'm trying to fix it with soldering tool))))))

personally i would want to fix it too. its just annoying that they use the plastic circuit boards. do you have a picture of what you fixed?

Just a wire from pin 15 to mosfet))) This week gonna get microscope, heat up board to get it off allum case and fix the trace) Will make pics if succeed
