Hello, my name is ***** ***** I will assist you today. If they installed a used ECM, then they should have reprogrammed your Durango's VIN number into it. If they did not, then that is why the light is on (mismatched VIN). Go back to the dealer and ask them to do that. This should take care of the issue.
