Hi everyone

Michael Diagnostician Champaign, Illinois Posted   Latest  

Good afternoon everyone. I just joined diag.net and I am happy to be on here. I'm a Transit Bus Tech from Champaign IL. I specialize in HD Diagnostics. I am also a Trainer and I just started up my own business dealing with Mobile HD Diagnostics and Training. If anyone needs advice from my neck of the woods let me know. If I don't have the answer I have friends that probably can. I have tons of known good scope files for HD as well as scan tool data and I'm looking forward to sharing what I know. Everyone have a good day.

I'm going to do my best, thank you. Hopefully some HD manufacturers will show some interest for this site and in the process of that maybe I can get them interested in using a scope.🙂

Good to have you Michael, welcome!

Which HD lines are you most familiar with? Do the OEMs in HD tend to develop their own engine management and emissions systems or are there a few companies that develop those systems and adapt them to each engine / vehicle?

A large amount of LD / MD automotive is fitted with Bosch or Delphi systems. I’ve heard HD can be difficult because the vehicles are often piece mealed together from different manufacturers leading to a situation where the tech has to diagnose the systems separately and kind of glue them together. I.e. the schematics of one OEM end at a connector and the schematics of another pick up on the other side. Or one scan tool is used for the engine, one is used for the transmission, and one is used for emissions.

Tier 2 emissions standards kicking in from 200$-2009 or so radically changed automotive Diesels, how do you feel about the impact on HD?

I work on Cummins, Thermo King, Allison Ep 40/50 Hybrids, just started working on Bae Hybrids, Zf , New Flyer and Gillig body electrical systems, Ford E350 and 450 Gas, used to work on Detroit Diesel DDECC 2 and 3 systems with series 50 Engines, Meritor Wabco Abs. And yes it can be challenging working on these types of vehicles if you don't have good schematics because the wires change color and numbers sometimes. With monitors being included now on the new vehicles though I'm hoping things will get easier. But I'm not holding my breath.🙂

For scan tools you have to hook up one at a time for each oem. However their are some aftermarket scanners now that are capable of doing system scans which is nice but from what I have seen so far they don't give you all the info on the code or data so then you have to go in with oem. And as for the different engines from each manufacturer using their equipment or from an outside source nothing is set in stone, it all comes down to cost in my opinion. For example Cummins uses Bosch components on their mid range engines and Allison's HP 40/50 Hybrid uses components for their battery packs from an outside source, can't remember exactly where they get the battery pack parts from but I think its Panasonic. I will have to dig into that and find out.
