- Heavy Duty Truck Scanner HD601 All System Diesel Diagnostic Scan Tool fits for Cummins, Detroit, Freightliner, International, Paccar, Check Engine for Truck & Car 2 in 1 Code Reader

It’s a cheap way to check the codes on my Peterbilt! I have to take it to the dealership or a truck stop and Loves charges $80 to check and clear a code! It’s easy to use and easy to figure out how to use!

Worked great. Good instructions. Easy to use.

I have a 2020 Freightliner cascadia with a dd13. This product does NOT clear the codes for the after treatment. And you can not force a regen until the codes are clear..... There for.... You are still S O L

Works on multiple brands. Good for quick diagnosis on the road. It gives detailed explanations about current, pending and historic codes. It's not bidirectional, and offers no emissions diagnostic, or allows a forced regen.

I have a 2007 14 liter Detroit series 60 that I have been chasing a check engine light that has been coming on and off for months. Purchased this scanner and literally within 5 minutes I had the problem solved. 1st the low coolant sensor was bad but I had already replaced it so I just had to clear the fault code. 2nd I had a bad ABS sensor on the right side of the steer axle. The actual reading from this scanner said" axle 1 right side " This tool is well worth the money and very easy to use. I had read many different articles and watched many different videos on the " ECU 128 " code but had no success. In my case I had fixed the problem by replacing the low coolant sensor but did not realize it because the check engine light still kept coming on but it never stayed on, it would come on and off and always off when I would come to a stop. I had to clear the fault code with the scanner and that got rid of the annoying on and off check engine light. Save yourself time and money and purchase this tool you won't regret it.

Love it

This worked to read the codes on a 20+ year old Diesel Pusher, Class A motorhome RV with a cummins ISC 8.3 engine. It read the transmission, ABS, and engine codes. This unit seems a bit over priced for what it does, which is just read codes. I suppose the advantage is that it can also read the ODBII port in a passenger vehicle as well, but I find it is just as simple as a $30 reader from the local autoparts store with ODBII.The 3 stars is a reflection of the price/value of the product. Almost a hundred fifty bucks for a simple code scanner. This unit should sell for a third of the price.Updating the software was easy using a windows 11 computer.

This scanner worked great on the purchase of a 2013 freightliner Cascadia truck. I was able to scan the truck prior to purchase to know that I was getting a vehicle without hidden problems.

The product is nice and useful, my father-in-law is using it in our auto repair shop and working nicely. This product is legit

It seems to work well.

Replaced my crappy orange Ebay reader with this, tons more data and much easier to use, no need for a seperate little booklet with only partial codes.... Works great for OBD2 check engine codes.

Not what we needed but functioned according to spec. Would have kept in toolbox but had one that did most of what this one did already. Active graph a little small to appreciate. Would have to use function of downloading info and viewing on larger laptop....like less fuss thanks. Quick refund issued. Good communication. Would buy from them again.

Worked well for me.
