Engine Diagnostic Code Readers

[MarkyDee]

Couldn't find an appropriate section to start this on, but I'd like to get opinions on engine readers such as the CanDo HD Mobile:

CanDo HD Mobile for iOS and Android Review - Diesel Laptops Blog

I'd like to build my own J1708/J1939 reader, but I don't have the time at the moment. But $499 seems really STIFF for something like this....

Thoughts???

There is a diy design out there. I have lost track of the website. IIRC: it used a part from Elm electronics.

I went with SCANGAUGE II I got off ebay for $100. Not as advanced as some, but quick n dirty

Hey Rusty,

I Googled that and found only ODBII versions. Do you have a link to the J1708 version?

Thanks

I THINK that if you build your own that you can download and use the Greenleaf software for free. I plan to test this out when I get time.

remember some of your engines may be J1939 and you'll need to build a circuit off of J1939 stuff.. Im nt a cummins guy nor do I know the big coaches alot.. but Big coaches tended to go J1939 before school busses did..

I know Navistar stuff up to 2007 can be read with the J1708/J1587 ELM325 based DIY scanner mentioned..

if you buy a newer bus and it has a 'MaxxForce' labelled engine then you'll need a J1939 tool..
