I connected to a German Tractor the other day with a Deutz engine,  PF-Diagnose is the best generic heavy duty scan tool hands down!  If it can't get into a module, nothing else will!  I have had Cummins ECMs that were going bad and Insite would not connect but PF-Diagnose got in with one shot! ...I had a CAT  3406e that several other guys checked, all said the ECM was bad...  one of the 1708 lines was corroded so cat ET wouldn't go in and guess what!  PF-Diagnose went in on just the one data line... Great tool I even used it to troubleshoot an Iveco truck!   Thanks Pocketfleet!  PF-Diagnose was the first software I bought when I was transitioning from car diagnostics several years ago and it has never failed to connect!

I can tell you this. Having PF Diagnose has been a money maker with diagnostics in my business. Emergency Road Service. This has gotten me out of more jams than you can believe. Guaranteed help from support is only an Email away and it's quick and I mean quick. What other company out there will remote into your machine if and when there might be problems. No one that I know of "EXCEPT"
PF Diagnose. I know the Forced Regen additions in the future will  just add more frosting on the cake.
Quality goes in before the name goes on. You think the OEM's would perform this type of service... No. All the others are glass and glitter. I commend the Admin for a well produced product with no comparison to the others. I have researched a lot of them.
Talking to a lot of other shops on what they have and use along with the price structure for support and renewals is eye opening.

Feb 15, 2016 - I was surprised when it worked on a new Fuso, I was able to pull codes, repair and erase codes and force a regen.

"I use it all the time and it amazes me what feature it has, even when compared to my OEM programs, and sometimes it connects when the OEM programs wont.  Great work ."

"Also tried your program on a Deere 953K buncher, 748H skidder. 2154D processor. Can test and read about 90% of what I could do with JD service advisor." Richy B. Contracting. Alberta Canada.  


"The John Deere 7800 was away, so I had a 6430 to check on PTO calibration error.  Communication Excellent!  Error code reported spot on!  Well done! Very grateful and excited!"  Leon van Wykn

" I am very happy with PF diagnostics so far, has not let me down once since I had it installed on the new Laptop with XP, works like a charm every single time, it has gotten me out of a few bad jams on the side of Interstate 84 in the middle of the night :) "  Vanguard Logistics

"We tried connecting to a Kobelco SK260 with 2 different and very expensive HD Scanners ( $6000.00 US + each ) and were unable to connect, then we tried PF-Diagnose with a DPA5 adapter and connected right away! Impressive!" Tyler


"G'day to all. I run an on-site/ mobile service and repair business down here in Australia, fixing everything from cars and small engines to earthmoving and mining equipment and of course heavy vehicles. Have been using PF Diagnose now for a couple of years. Great product with even better support! Have had good success on everything from LV to HD and earthmoving. Such an easy program to use with great features. Makes diagnosing breakdowns in the middle of the night a whole lot quicker! It may not have the features the OEM software does, but as a pure diagnostic tool that covers a really broad range of equipment, it really punches above its weight. Keep up the great work!" A K Diesel  Australia
