Now I need to go check mine. I used the tire lift on my two other trucks, but I honestly don't know that I've ever had my M1079 spare down. I checked the tire presser once a year, but did that in the stowed position.

Yeah, I got a popup stating: "Cannot load Injector Trim Calibration from the ECM." I'll have to doink around with it tomorrow. As I said, the Trainer also runs that same error msg (although I only played with one engine in the trainer).

I did get a backup made. I tinkered with the Trainer before attempting anything just to be sure. Interestingly, in the trainer it didn't get a snapshot of the injectors. And the same thing happened when I made the actual replacement file for the truck.

Big old wall of unhappy red. I tried all the various combinations of Vendors, Adaptors, and Protocols. All red and dead. The only thing that flagged me was it says I have an .ini file that needs replacing. It did the same with the DPA4+ and I tld it to fix the file...

Looks like the second reader I picked up (DPA4, not a Plus) isn't talking. It has power and I can see it POST as startup (all the lights work at start) but it's not passing a signal to the PC. I'm using the known good DPA4+ cable. I have the DPA4 and DPA4+ drivers installed. And...

Thanks. Will do.

After so many wrong cables (to include the J1708 Deerborn originally sent me) and the ones I got off Amazon that were wired VERY wrong for a DPA and the one that came with my DPA4 that is also wire differently) I just wanted to be absolutely certain before I plugged something into...

And that was likely where my assumption failed. I was looking at the 15 pin male cable end clearly shown in the documentation. And my assumption was that the J1939 end was also the cable end. And I do see the cable/receptacle clarification now (down in the Type-2 Introduction...

Except for the parts where the documentation labels the plug looks to be incorrect/mirrored. *specifically look to C & D (the CAN J1939 hi and CAN J1939 lo) *according to the document diagram (J1939 end) , C & D are not used on the male J1939 end of the cable The document is...

Appreciate it ! Thanks for taking the time.

Yeah, that's the plan. But I can't seem to confirm that the DPA4 and DPA4+ have the same pinout/cable. That's what I'm after. How is the DPA4 wired? Same as the Plus? The documentation from Deerborn indicates they are the same. But it also lists the pinouts...

Now if I can confirm the DPA4 cable pinout (not the plus) I'll have a second reader that I can pass along to someone. I'm....hesitant.....to hook it up with the cable that it came with given the alteration in the pinout. In *theory* it should be using the same pinout as the...

OK, SUCCESS for the most part ! I downloaded Deerborn's little diag tool and it confirmed that the DPA4+ was in fact talking to the CAN J1939. So this pinout is in fact correct for the DPA4+ Next was a mino settings issue with my CAT ET software. I dug down into Utilities...

If the "Deerborn" document is to be trusted (which I suspect it fully cannot): C & D (which are empty on my cable) are CAN J1939 lo and CAN J1939 high Either the doc is wrong (which I suspect) or this cable is wrong (which I doubt, but it has no part number tag from Deerborn). Just...

So yet ANOTHER $80 thrown at this on cables since nobody bit at my above request....and still cannot make heads or tails of things. I'm in $400 on this DPA stuff and beginning to think I should have just stuck with the Bluefire and looked at the pretty gauges. I ordered the above...

Cool build for what they are going to use it for. I'd have gone another route for an "overlander", myself. I doubt anyone will ever sleep in it. But it's clean looking...

OK, I had to go look at it. I remembered wrong. Under the little rubber cap is what appears to be a test light with a push buttoon. I'd never really looked at it closely before and just thought it was a two-prong port. LOL Yeah, what ever that is unscrews and behind THAT is what...

Can someone with a DPA4 or DPA4+ (or I'm guessing a DPA5) do me a quick favor? Can you match the 9 pin ((letters) to the 15 pin? I have the tech brief from Deerborn, and I now have three cables here in front of me and none of them are wired even remotely the same, and none of them...
