Fuel gauge and DTE out of calibration after electrical short.

This is about my 2016 Chrysler Town and Country Platinum/Limited Van.

I had a major electrical short at the harness pass-through on the firewall.  I repaired it and everything was working only now the Fuel Gauge will not indicate above ¾ tank and the DTE value is all wrong.  Also the side door close buttons at the center pillar are not working although the overhead controls are.

I read that older model T&C’s have a feature where you can reset/Diagnose the instrument panel by pressing the odometer button, however my van has the fully electronic instrument cluster with no mechanical odometer.

Any help would be most welcomed.

Tks,

RC
