*** Diagnostic Computers for Skoolies ***
 
Hey Skoolie Fans, Just wanted to share with you some info on diagnostic computers for my bus.

I know there's lots of hearsay about electronically controlled versions of buses but I feel we have been taking the wrong perspective about them. Yes mechanical buses will always be easier to troubleshoot but if you have the right tools on hand the problems will be much less stressful to correct.

I have found a really helpful company. Diesel Laptops

I spoke with Patricia the tech rep and she and I found 3 different price points and levels of tools that I could use to repair my bus with out taking it to a shop for a code scan.

You can also preform shop only maintenance, such as forced regen and reflashing of ECM's.

#1 Top Tier for my bus is this kit. Universal PF Diagnostic Kit

Yes the price point is really really high but the resources and tools available are on-point for a owner who wants to free themselves from dependency from a diesel shop.

#2 No Laptop sold to you, you use your own. DieselLink with PF Diagnose.

This package is just the software and the DieselLink. You would still need the cables that actually connect to the ECM and some other programs that help you look up codes and wire diagrams and Tech support. Still a great tool but after all is said and bought you might have spent just as much as the first kit.

#3 This one is a very tempting entry option. CanDo Bluetooth Mobile Scanner

Out of all the kits this is my favorite...This one allows you to do many of the tasks of the Top Tier Kit but it does not have resources for codes and prints and engine diagrams.

As of now I have not purchased one yet. I am really leaning toward the Universal Kit just because I know that I will have another bus one day and I really enjoy the idea of knowing whats wrong with my bus if I do need to use a shop for major repairs. Just a piece of awareness and mind.

However the CanDo kit is still very capable and if I save enough for the Universal Kit I can still get it and save some moola.

So that's my rant. Really interested to hear what you think.

Off the work on the bus. Looking forward to seeing the comments below!

:Thanx:

Oh yeah watch the included videos...I am sure there is lots of information and options that I didn't include that will surely be mentioned in the short YT videos.

diesel laptops is a cool company.. i bought my NexiQ scanner from there..


as for software.. navistar gives away servicemaxx J1708 for free which will do code reading, injector tests, etc.. and can reprogram items like speed-limits, cruise control, idle timers and the like.. it wont do horsepower changes or critical parameter changes.. I have a "Version" of servicemax that will...



allison software can be had for the looking on various internet sites.. *Cough* m h h a u t o


same with CAT ET and cummins programs..



to upgradethe internal firmware on a Navistar ECM you need a legit subscription to NavKal.. which I have and am willing to update the core on anyone;s IH ECM I get in contact with..

For my mbe906 I have used the scangauge d. It works good enough for general codes. At some moment in the southwest I blew the computer controlled hydraulic modulator valve to the hydraulic cooling fan. Although the code on the cangauge was not exactly accurate it was good enough to get me to the point and repair it.

Werewolves ( forum member) lend me a Nexiq clone but I did not get enough experience with it.

I just bought Nexiq clone of fleabay but have not played around with it. For me the Detroit software and the Allison stuff is most interesting.

Which ever scan tool/diagnostic tool you are interested ASK if it will deal with proprietary mfg parameters. In the case of my Isuzu turbo diesel powered skoolie, ONLY the dealer level scan tool will communicate with the computer. Even so, it was worth it to me to pay the big bucks ($1500 or $1800 I can no longer remember) to know if I break down somewhere out in BF Nowhere, even Bubba will be able to figure out what is wrong.

Will any of those talk to MBE?

Thank you for the info, but will any of those work with MBE?? Maybe I missed something in your reply.

:rofl:

I will look that up.

You know it's pretty cool what you can find on ebay.....from deep muscle massages :wink1::whistling::rolleyes:

To diesel engine diagnostic software, I'll take a look at Nexiq see what comes up. Thanks.

DoxieLuvr2015 12-14-2019 05:29 PM

I will keep that in mind

Ol Trunt,

Ja that was one of the many of the concerns on my shopping list. If I am going to invest in a kit like the UNIVERSAL it better be able to do proper diesel repair shop work without the annual fees....hopefully. I will reply to the emails I have from the DIESELLAPTOPS.COM customer service and see what they say about that?

:Thanx:

Thanks for bringing up this topic -- it was a real concern of mine when I was given a bus with a 3126e /A2000 How do I troubleshoot this thing...?

If I was actually going on the road with my bus full-time I'd probably get this
https://www.diesellaptops.com/collec...mercial-trucks
It'd be like towing insurance to me...

I would consider getting just a software I could load to an existing scantool
or laptop.

I havent tried to locate actual MBE software yet.. the Detroit Diesel software will connect and allow some parameter changes on the MBE engines.. DDDL (Detroit Diesel Diagnostic Link)... the afformentioned m h h site has some versions of said software.. the Detroit Diesel bus I will soon own is too early to have a computer so i havent the need yet to explore it...



Factory parameters require some form of software that has made it outside its normal "dealer cage".. most of these older engines from the 90s / early 00;s, paramter changes can be watched going through the J1708 link. and very few actually have Hashes associated with them.. so the software itself limits the change, however doing a direct write of said parameter nets good results..



some programs like navistar Servicemaxx Pro L3 have an engineering mode that navistar employees would place it in and change parameters over Teamviewer sessions.. these are pretty easy to Dupe and have forever access if you know what you are doing.. I believe CAT ET has something similar but ive only gotten a little ways into it as i dont have a CAT of my own or a bench ECM to tinker with..

Diesel Laptops are really good. We have a Texa at work. I recently used it to change my governor to 75 mph and while in there noticed it could do a fair bit of programming including how throttle input affects shifting. I also remember seeing Mercedes as a selection under Freightliner.

(Looking for the emoji of anxious kid raising his hand saying "me, me, me!")
I will happily provide a 3126e test bed for you to hook up to and see what you can see!

I will even serve you fresh coffee on the bus while you're doing it! :bow:

It would be awesome to learn some things about my setup and what changes to it would be safe (reliability & longevity) to improve performance.
Just learning how to do a basic diagnostic health check would be amazing.
