Welcome to Just Answer Dodge my name isXXXXX realize that all my answers are based solely on the info you provide me......

Your P2181 code can be set by a bad thermostat, so replacing the thermostat is the best place to start.

Your 4wd system will also set fault codes but you will need a scan tool capable of reading these codes because the same way you got the 2181 code does not work for 4wd codes so this means a visit to a shop unfortunately.
