What Customers Are Saying

Customers are divided on this diagnostic tool. Many praise its affordability, ease of use, and ability to read codes, clear check engine lights, and display live engine data without requiring a smartphone—helping them avoid costly repairs. However, a substantial group reports serious frustration with software updates and registration, citing serial number validation errors, broken download links, and Windows-only support that leaves other users stranded. Some note build quality feels cheap, with USB connection issues and small display text. Despite strong capabilities, unresolved software problems have led several customers to regret their purchase.

Not Connecting to some vehicles

Would Not Recommend

I have tried this on several cars. Most have worked so far. I finally got the software updater to work, but there are never any updates. I was hoping an update would fix the problem I have with it not connecting to a GMC Suburban and a Chrysler Town and County.

It really comes in handy when a problem arises.

Would Recommend

I already had one and it has helped me out many times. It prevented me from having to go to the dealership and pay their outrageous prices just to diagnose a problem. This Code Reader I purchased for my son. He immediately used it to diagnose a problem on one of his vehicles. Saved him a lot of money.

TRASH

Would Not Recommend

Trash. No way to update it. Craftsman.com has some shady software that downloads on your desktop then asks for money. So you pay and nothing happens. Just straight garbage!

Great product

Would Recommend

This isn’t a $800 scan tool. But for the 10th of the price get a lot out of it. It tells you the faults codes and what can cause it. When your done with your fix you can clear them. You can look at a tons of live data and history of the engine. Anything from bank trim, coolant temperatures, engine RPM, throttle position, and much more. It can also tell you what cylinders might be misfiring and how many times. It even told me things that don’t cause a check engine light, like low coolant efficien...

Wish could find software updates

Takes them over an hour to even bother getting back to you and can't find anywhere on the web page software updates

Built well but software does not work.

Got this to use for future maintenence. I checked it on my 2009 Tacoma which I know has codes for the TPMS and ABS system active and it didn't pick up on any of them. I figured the software update would fix that, however when I go to use the update tool, it says the device serial number doesn't exist, and so it doesn't update. Will return unless the software issue is fixed. TLDR: IT DOESN'T READ CODES.

Unable to update tool

Unable to get update on the reader. Downloaded the software but it would not allow the update. Always purchased and trusted craftsman. Unfortunately this was a huge disappointment.
