iCarsoft HD V3.0 Heavy Duty Diesel Truck Diagnostic Scanner Tool Code Reader

I recommend this code scanner. I purchased this model because of features --- especially its ability to scan diesel trucks and cars --- and price. It worked very well when I received it, testing it on my 2015 Hyundai. A few months later, I had a "check engine" indication on my 2019 RV, built on a Freighliner/Cummins chassis. I hooked up the HD 3.0 using the J1939 adapter, but had difficulty making an electronic connection. Using the Amazon link to contact the seller/manufacturer for support, I opted to write an e-mail so I could provide details. I was pleasantly surprised to hear back the next morning with a couple of specifics questions, including requesting details about the vehicle. I responded within a few hours, including more details about the step-by-step process I performed connecting and selecting a test. And, importantly, information noted on my on-board readout and indicator lights. The next morning I received a zip file with a software update that fixed my issue. Bottom line, using e-mail we were able to exchange information that helped tech support quickly provide the software solution. I was very impressed.

This product couldn't even read a single code on my Freightliner Truck the very day I needed it. Had to call emergency roadside to help out. For the price, this is JUNK. I am definitely sending it back

Wasted my money on this one. Might work for other brands but I don't own any of them. Should have been clear, NOT FOR PACCAR.
