I'm getting tired of going to autozone everytime I get a CEL light. I'm looking to purchase an OBD2 scanner, but I'm way out of my league here. I am not a techie of any sort. I want an easy to use scanner that just displays the code and that will reset the CEL light. I'm more than happy to wright down any code and google them later. And I'd like it to be cheap. Any suggestions? Thanks

The most cost-effective scanners are usually Bluetooth obd2 modules with an accompanying mobile app on your phone. I use Jscan for the JLU and Torque app for my other cars. If you search "jscan" on this forum you'll find a number of posts explaining details.

You'll also need a security bypass cable to be able to reset error codes on 2018+ JLs.

For me $:

- $12 for Bluetooth obd2
- $22 for Jscan
- $20 for security bypass cable


Note: there many, many more things you can do with Jscan like modifications to your vehicles settings (example tire size, Led lights etc.) but that gets a little technical

Any cheap scanner will be fine if you are willing to google the code. Walmart, Harbor Freight, Auto Zone, any of them are fine. OBDII is a standard and any reader will check and clear codes.

You're probably right. A cheap scanner will be much simpler (not less $$) for someone looking for very limited functionality. However, you may still need the security bypass cable to clear codes. The consensus on this forum is you can only read codes without the security bypass cable on the 2018+ JL.

I think the bypass is only needed for programming. If autozone is clearing them without the bypass then any other scanner sending the clear command should work.

It would be good if someone on this forum could verify clearing codes on the JL works without a security bypass cable. It wouldn't be the first time a forum's consensus was wrong :facepalm:

Thanks for all the replies. I'll just add a cheap one to my next amazon order. I'm not trying to clear codes on my JL, but on a couple of older vehicles I also own. Never had a code on the Jeep. I was out wheeling the other day with a group and one of the older jeeps went way out of time. One of the other guys had his scanner and quickly diagnosed a distributor malfunction. Of course he was a real mechanic and had a very good scanner. Way beyond of my backyard mechanic level. Thanks again.
