Best OBD II Code Reader

I bought whatever they had on the shelf at AutoZone, but I’m not very happy with it. What are the best OBD code readers out there that you have used?

 

That's a loaded question. There are hundreds of them from $25 to $6,000.

What capability and budget are you looking for?

What don't you like about the one you bought at Auto Zone?

 

Good point, for general DIYer use, nothing pro, and ideally not trash. I lean towards an app-based platform, like the one I bought, but the app and reader leave a bit to be desired. It doesn't correctly decode my 4Runner so I have to manually enter vehicle information every time I go to use it, and it's pretty slow, even for an OBDII reader. Full scan takes 5-10 minutes.

 

For an app based, basic code reader without bi-directional testing the Blue Driver is popular, reliable and affordable ($100-$120). I wouldn't call it fast, but full scan on a 4Runner doesn't take 10 minutes. You won't get speed out of the cheaper, app based bluetooth scanners. You will have to step up to a pricier, dedicated unit for that.

Non app based but a step up with bi-directional capability for just under $500 the Autel MaxiCom MK808S Pro is a nice tool

 

I have a Blue Driver and am very happy with it. It is a nice balance between cost and function. It currently meets my needs.

 

Doesn’t the Carista read codes?

Cheap and you can program things like window roll down with remote.

 

Yes, but it's subscription based so if you continue to use it it's roughly $100 for the first year and $50 every year after that.

 

For me, Carista was worth $45 to save money I would have spent to program features at the dealer, but once I was done with that I never needed again and let the trial period expire. I don't consider it a long term solution for a code reader.

 

I have been using the OBDLink MX+ for a number of years. It's compatible with a number of apps if you don't like the one it comes with.
