Hi guys! I'm new here, and I don't really know where to start. Maybe my desperation for help is preventing me from introducing myself properly. I'll do that in the appropriate thread.
Here's the thing: I repair computers at the electronic level, desktops and laptops.
A dear friend asked me if I could check his ECU, and I said no until he convinced me.
The problem is that he doubts that the ECU is the problem. He doesn't have 12v of PCV+ or SCV, so the truck won't start.
I've been watching tutorials and guides, but nothing makes sense to me. I have a hard time understanding certain things.
What did I do?
First, a visual inspection. Nothing damaged. I measured the diode components and found no short circuits that I am aware of. (FET transistors and some diodes).
I can already recognize certain sectors of the ECU: I have these voltages: injecting 12V to B+ and (E5-1) IGSW (E5-9) MREL (E5-8) with their negatives in this case in common with E7-7: I have a consumption of 200mA. If I disconnect the IGSW, I have 190mA, which caught my attention since they say it should be 300mA.
How can I really know if the PCV+ suction pump is working? I would really appreciate it.
I have an oscilloscope with a signal generator. or rele-
I am sharing the manuals I am using with you.
thx for help guys! <3
