Multiple codes and MIL light suddenly coming on after emissions testing on my 2005 Caravan

Question

One year ago, I was coded for a small emission leak. The MIL was on all year.

Prior to emission testing it was suggeted that I should try reset it and I did this by disconnecting the battery and driving the car for about 500 km and the MIL never came on.

The MIL stayed off. Prior to the emission testing I replaced the fuel cap anyway and I undid the battery thinking it might need to reset again with the new fuel cap.

The car however was returned to me with the MIL on. and showing 3 new codes. U0140,U0155 and U110C..What could cause this to happen and what shouldm I do on a mudget?

thanks

Answer 1

U0140 No Body BUS message

U0155 No cluster BUS message

U110C No fuel leel bus message

What set these code , was having the battery disconnected, by disconnecting the battery a  quick battery relearn procedure has to be perfromed.  The battery relearn procedure is done by a scan tool that has the software to perform a battery quick relearn  for a Dodge / Chrysler product, just by not doing a battery quick relearn procedure you can also set a P0700 which is a transmission fault detected MIL light requested on .with no other code condition.
