You need a scan tool to read fault codes.
Get a fault code by cycling key from 'off' to 'start' 3 times, leaving the key in the 'run' position. Any current fault codes will be displayed. On the 2000 Durango, faults are displayed in the odometer field, not sure about the 2003. Once you get your fault code, show them here, it will help us help you better.

Because the computer has detected a fault and turned it on.
last one to touch it is at fault!! take it back & make them fix it.
Trouble code P0753 means: Shift Solenoid A Electrical
An engine light check means some fault in the engine . Check the handbook to get more details to find what and where the fault is.
you need to have the check engine/service engine soon fault codes read to determine what the fault is.
I would check for any fault codes first with an obd tool, is the check engine light on?
If you are checking a Chrysler/Dodge 55 is "end of message". It just means that there are no more codes to show. If that is the only code you got , then there are no codes.
