If the Fan control box looses the CAN connection to the engine controller (which knows the engine temperature) the Fan will run at
maximum speed in order to protect the engine.
Therefore, Check all connectors for moisture and/or galvanic corrosion. Wiggle and dis- and reconnect the cable
that goes to the Fan controller.
