I had a cel a few days ago, so I purchased a scanner, a ACTRON CP9580. The problem turned out to be an O2 sensor. I have since fixed the problem. My question now is does anyone does anyone know how to reset the cel using the model listed above. I do have the owners manual that came with it but it doesn't explain how??
Should be options to read codes, and clear codes in its menu. Must be koeo(key on engine off) to clear codes. It should clear them, and you should be able to go right back and check for codes, with none showing. Most OBDII codes will require the engine to actually run or attempt to run before codes will trigger.
I know that most jeep owners are not going to spend the money we do on scan tools, but keep in mind stuff put out by actron, and other budget priced tools aren't really great for diagnostic work. They leave a lot of information on the table vs the better stuff.

(stone cold start and a good run so it might take a few days before it is gone).
