That’s an awesome find! Having a list like this is definitely a goldmine for anyone who likes to DIY their Jeep repairs. Those error codes can be a real headache when they pop up, especially if you're trying to figure out what's wrong without going to the dealership. This list is going to save a lot of us some time and frustration. Thanks for sharing it—I’m sure it’s going to come in handy for a lot of us next time the dashboard decides to light up like a Christmas tree!
