Just came across this, (it's a cut / paste, excuse the formatting) apparently you can pull up trouble codes with the ignition key:
Insert the key into your ignition. Rotate it to the "On" position (third position) without starting the engine.
Push inward on the key (toward the ignition), and quickly rotate the key from the "On" position to the "Acc" position (second position) three times, ending in the "On" position.
Pay attention to the lights in your instrument cluster. If you've done everything correctly, all of the lights will light up and six dashes (- - - - - -) will appear on your odometer for a brief period.
Observe the odometer and write down any diagnostic trouble codes that it displays. The codes should appear immediately after the six dashes. If there are no codes in the Jeep's computer, the odometer will read "-done-" after the dashes.
Rotate the key to the "Off" position, and remove the key from the ignition.
