There are no codes. The E-light on the early MJs is on a mechanical timer set to go off after about 80k miles. It does not mean that there is anything wrong with the truck. The timer is a small clear box under the dash. Just unplug it and forget about it. Unless you live in a state that requires you to maintain it, then you need to get a new one at the dealership.
Jeep on!
