http://www.cornwelltools.com/webcat/products.php?product=OWC3418-%2d-Heavy-Duty-Code-Reader I have one it works pretty good

 

Nice looking product!

 

What a reason? All new trucks got digital dashboards all codes may easily be read with

 

Depends on model of truck peterbilt,kenworth don't at least the ones I work on and he's Probly got an older truck with a standard dash

 

yep, it is style of Paccar, DAF for example reads - Engine WARNING ore ECAS WARNING and no fault codes on display.

But all modern Mack, Renault, MAN, Volvo, Iveco, Mercedes, Freightliner, International, Sisu... all display codes, some code only, some description and freeze frames

 

columbia reads codes in MID XXX SID/PID FMI standard
MID 128 - engine ECU
MID 130 - tranny
MID 136 - brake system
MID 140 - dashboard
MID 144 - VECU
....

 

It works pretty good I mean it dosent let you do any tests or anything but it gives you the code and description of the fault a lot easier then pulling the laptop pricesout I think you can get it cheaper by shopping around its made by otc and both cornwell tools and matco tools sell it so I would defintly compare
