Dodge don't supply much information on this code. It says it is for a fan control relay but the truck doesn't have a control relay for the main engine cooling fan as it is a viscous coupling mechanical fan.. It does have a relay for the air conditioning condenser fan. See if when you operate the air conditioning does the condenser fan come on. Powertrain control module grounds the relay, the relay for this fan needs power at fuse #39 (25 Amp) then brings power out the dark green wire to the condenser fan.
