Intermittent P0481 and the COOL FAN HI 25 Amp Fuse Is Open

The Cooling Fan S/P relay may have an internal short a and cause the COOL FAN HI 25 amp fuse to go open. Check the LOT code on the side of the Cooling Fan S/P Relay which is located at the left front corner of the engine compartment, below the left headlamp assembly, attached to the frame. If the lot code on the relay is 4075 A2 replace the Cooling Fan S/P Relay. This concern can sometimes be duplicated by shaking the Cooling Fan S/P relay or wiggling the connector to the relay.
