Here is what the underside looks like this is a close-up of the solder connection on the main board And here is a close-up of the solder points on the connector

Yeah, get the pinout . Won't hurt to have it here.

Looking it over quickly I saw a diode that doesn't seem too happy.

Well, regardless I have some first pictures of what the ECU looks like without the potting.

OK

good idea. you just have to heat it just enough to not melt the components off

They are using Low ESR Nichicon capacitors in this unit . I can't wait to see if they got out of value. So I see already I can melt this stuff with my rework station. Good thing I got an awesome fume extractor , because these fumes are nasty. Wearing my respirator , too.

there is a bleed screw by the secondary filter, that is what you're supposed to open to bleed and then prime with the pump. Did you do that?

I dont remember 100% but i dont think that's how it is supposed to go

Isnt there q push button one needs to push to prime it? Also fill the filters with diesel before screwing back on?

That's actually a benchtop multimeter, the oscilloscope is left of that . On top of my HP 8543a power supply, haha

I am going to make a tutorial. How to fix your CTIS-ECU without paying ransom

Look what I just found... Let's take it apart Mine is from 07

Thats interesting. I think to remember that the ECU in the box I took apart was facing the opposite way. I don't think the two Capacitors were facing toward the lid in my example. **** I wish I hadn't thrown this ECU out.

The CTIS unit I took apart a few years ago had a silicone kind of potting, too. I seriously doubt that m-35tom will disclose how he removes the material. I want to know now though, So I'll do some research. I think he used heat to soften and melt the silicone. I'll report back with photo's and...

@plasa you're welcome. I am glad Suprman and I were able to point you in the right direction.

Can you elaborate more on how you remove the potting?

The ECU can be reprogrammed. But on the original (A0) truck it is very difficult. On A1 trucks it can be done with a laptop, the 'Dana diagnostic tool' software and a dearborn adaptor. There you just plug the laptop in change the target tire pressure and save. But even if the pressure is too...
