You can get the codes yourself by doing the following:
Put the key in the ignition and turn the key to run (not start), then off, then run, then off, then run (that's 3 runs and 2 offs). Leave the key in the run position.
On TJ's with a digital odometer, the code numbers are printed on the odometer in addition to flashing the check engine light. 55 indicates the end of all codes. Once you've got your code list post it back here for more info.
