Vehicle Diagnostic Self-TestSelf-Test Procedure:Hold in the trip odometer reset button while turning the ignition key to run will start a self-test, with a readout on the odometer. It will also activate the instrument panels, one at a time.The test will run for approximately 60 seconds, then automatically shut down. If everything is working correctly you should not see any faults. If you notice a fault refer to the corresponding Chrysler fault codes below. They may help you determine the nature of the problem. |
| Error Codes | Description of Error |
