(Yet another?)Check Engine light question
Stock 2011 Rubi. I was running a relatively rough trail (skid plates on the bottom got hard beating), at some point check engine light went on. Was on all the way home, nothing unusual in Jeep behavior/handing though. Came back home, disconnected the battery for 5 minutes, reconnected and the light is now off. Doesn't come back, Jeep runs as a charm. Anything to be worried about ?

That will work. Or, you can use the built-in DTC reader ...
1. To check your Jeep JK Wrangler’s DTC codes, simply insert your key into the ignition, turn it to the ‘ON’ position but do not start the engine. Then, push the key into the ignition cylinder and while holding it in, turn it to the ‘OFF’ position and then back to the ‘ON’ position (3) times straight making sure to end with it in the ‘ON’ position. It is important to keep pushing in on the key to prevent it from catching at the different positions along the way.
2. If you do step #1 correctly, all your dash lights will illuminate and your odometer will show up as a series of (6) dashes. If your Jeep JK Wrangler has any logged in any DTC’s, they will be displayed soon after the dashes appear. Write down the DTC(s) and check it/them against the list below to find out what they mean.
3. If your Jeep JK Wrangler has not logged in any DTC’s, the dashes on your odometer will be followed by the message ‘-done-’. Turn your key to the ‘OFF’ position and you will in fact be done.
I own a code reader, so have never tried the procedure. But, I expect it works in all model years.
