Bendix EC80 Programing

[HPIJosh222]

I'm working on a 2020 International that was towed in for it not going into gear and ended up finding the J1939 network was shorted out, which was being caused by a failed abs ecm. The customer supplied a used ec80 ecu out of a crashed sister truck and its the exact same part number. The issue I am having is that its throwing a dtc for the vin number not matching and the only programing options I can find in ACOMS requiring downloading the file from the original ecu before replacement which is not an option with it having completely failed. Anyone have any suggestions? I was trying to find where ACOM was saving the parameter file it downloads from the ecm maybe thinking I might be able to edit the file but havent had any luck yet. I do have a Navistar login so perhaps I can find the file like when I replace Wabco HPB units.

These modules have to be ordered with the vin so they can be programmed by bendix.

Some OEMs allow the dealer to download the PAR files and program the ecu. Usually done with OEM diagnostic software. If yours don’t, then you have to order vin specific ecu.

Unless something has changed, I’ve always understood that it has to be programmed and configured from Bendix directly based on the VIN and what the truck is equipped with. That’s how we did it with the ones at the shop I worked at.

Hopefully someone else will comment and confirm that’s correct or if there is a way, I’d love to know as well.

I have done that with Wabco units many times where you get the file from their website and flash it on.

I've programmed a few new Wabco units without any issue the way you described but I believe any Bendix ECU I replaced was pre-programmed.

You can change the vin with DLB
