Jeep Wrangler TJs have the ability to display error codes on the odometer. If your check engine light comes on, just follow this procedure:
Key off, push and hold the trip reset button.
Turn key to run (not start) and back to off again.
Release trip reset button.
Trouble code should display in the odometer window. If the gauges run through a test run and the odometer cycles through all numbers like 999999, you released the trip reset button too early.
