I assume you are asking about the "check engine" diagonstic codes.
You can check the codes yourself by using the key and ignition switch. With the engine off, put the key in the ignition and turn it ON-OFF-ON-OFF-ON -- do not turn to the extreme right "start engine" positon, but to the last click just before the start position.
You will then see a code list read out where the odometer (mileage) usually displays. It will start with dashes in the readout "-------", then each diagnostic code will appear in sequence like P1684, P0700, and then the word "done" after all of the codes have been displayed.
One word of warning -- I have found that sometimes all of the diagnostic codes do not display with this method, so it would be best to also check the codes using an electronic diagnostic code reader. You can do this for free yourself as explained below.
Go to your nearest "national chain -- do it yourself" auto parts store such as Auto Zone or Advance Auto. Ask to borrow the "engine code reader diagnostic tool" -- you will have to give them your driver's license to borrow it. Then, in the parking lot, check the diagnostic codes yourself.
Turn the car key to the "accessory position" -- i.e., not started, but with the accessories on. Power on the diagnostic tool. Plug the attached pin connector into the Chrysler diagnostic socket located just under the dasboard below the ignition switch. Press the "read codes" button on the diagnostic tool -- you will see a diagnostic code and a brief message about what it means. Keep pressing the "next" button until you have read all of the codes.
P.S. Don't forget to get your driver's license back when you return the diagnostic tool!
