The instrument cluster doesn't like when the battery loses power or power isn't maintained while the battery is being changed. Codes can be pulled from the cluster.
Caravan cluster self test
Turn ignition switch to OFF position. Press and hold trip odometer reset button. While holding button, turn ignition switch to ON position. Continue to hold button about 5 seconds until the odometer VF window displays SOF and a number that shows software version. If any problems exist they will show you the code. It should continue to go through its self test and should reset the cluster.
