First thing you should do ASAP is pull an ECM replacement file. You absolutely need to have this on hand and backed up in places because it has truck specific information you need if your Cat ECM ever dies. Injector trim files, timing calibration, and FLS/FTS, are setting’s unique to your truck...

No prob man, I am super happy you got it all working, I feel pretty strongly that if folks take the time to understand the documentation and theories of the electronic diagnostic tools, these A1 and above variants of our trucks will stop getting this stigma of being hard to work with. At the end...

I couldn't see anywhere in that document where they mention that these pinouts are describing the cables. That information is specifically documenting the connectors on the trucks and DPAs, the cable to connect the two is left as an exercise to the reader. They mention the disparity between the...

For the folks following along, the linked document from the manufacturer is 100% accurate and can be trusted when working with factory cables.

Wasn't really quick, took about an hour but here ya go. I verified this with my multimeter on my factory Dearborn cable. This will match your Dearborn cable, all bets are off on homemade/Amazon Purchases...This cable will 100% work on DPA 4 or DPA 4 Plus

From the documentation I have seen, they are the same...

Did you read the manual for that code? It tells you what to check.

Have you tried plugging the ebay cable into your DPA4 ? If that works, rewire the homemade cable to match the factory Ebay cable, should be good to go.

From the WABCO manual: When I clear codes, light doesn't turn off until I drive the truck a little bit, usually by the time I reverse it out of the shop

That’s a nice looking seat. Where is it from?

I am jealous, mine didn’t have the rubber cover so mine is pretty weather beaten. When there are no ABS codes, when ignition is turned on, that light should briefly illuminate and then go out. If it is lit at any other time, there are codes. This is described in the manual but I believe when...

Also, I have never been able to get wabco toolbox to connect on 1939, I always have to use 1708 …. For what it’s worth

can you send a picture of the port you are talking about? 2male pins doesn’t sound right. Keep in mind, there is a “diagnostic tool” plugged into the 6pin port you have to remove to reveal the 1708 port for connecting the DPA

Closing the loop on this, I did confirm that if you get that cable I linked to above, besides being the right one for your truck side it also connects to the diag port on the M1082 so you can read ABS faults on the trailer as well. Looks like I actually have a sensor code stored… Glad I Checked!

Did you get a DS package with the IETM ? if you installed it it would have a DS Test Set Selector application that lets you pick "Serial ICE" which is what you have

@hike Once you have the TMs I did see a “troubleshooting data bus” procedure in the TM and it will step you through the process taking readings from your truck, using the ICE box that came with your kit.

None of those tests were 60 or 120 Ohms so doesn't that pretty much narrow it down to a bad resistor or am I missing something here?

a quick goog search shows some of those are voltage related, doubt it has anything to do with eco hubs, Mine never threw codes for that. the transmission will go into a relearn process, but that doesn't throw a code and it finishes the adaptive shifting stuff pretty quick. thats interesting...

Try switching the protocol to J1939 and Click "Run Test" and show screen shot please also try CAN

your problem to me seems very clearly a problem between your PC and your adapter. If the PC to DPA connection was good you would get a success message for that and a failure in the VDA to Vehicle window.. I would not be looking at your truck as the source of the problem at this time. I would...
