New Holland ENG 245 – Engine Controller (ENG / EDC7): Fan Clutch Voltage too low

This fault code indicates that the engine controller is detecting a lower-than-expected voltage on the circuit responsible for operating the electronically-controlled viscous fan clutch. This condition typically points to an open circuit, a short to ground in the wiring harness, a disconnected plug, or an internal failure (such as a burnt-out solenoid coil) within the fan clutch assembly itself.

1. 1

   Inspect the wiring harness leading from the Engine ECU to the fan clutch for chafed wires, breaks, or areas shorting against the engine block or chassis.

2. 2

   Disconnect the electrical connector at the fan clutch and inspect the pins for corrosion, moisture, or bent terminals that could cause an open circuit or high resistance.

3. 3

   With the key in the ON position, use a multimeter to verify that the Engine ECU is sending the correct supply voltage to the fan clutch connector.

4. 4

   Measure the resistance (ohms) across the terminals of the fan clutch itself to check for an internal open circuit or a dead short.

1. 1

   Disconnect battery

   Disconnect the negative battery terminal to prevent accidental electrical shorts.

2. 2

   Disconnect connector

   Disconnect the electrical harness connector from the fan clutch.

3. 3

   Remove fan shroud

   Remove the fan shroud mounting bolts and push the shroud back over the engine to gain clearance.

4. 4

   Unbolt fan blade

   Unbolt the fan blade assembly from the fan clutch.

5. 5

   Remove fan clutch

   Remove the fan clutch from the water pump or engine mounting hub. (Note: Pay close attention to the thread direction. Many New Holland fan clutches, such as part 82000845, utilize an M30 Left-Hand (LH) thread and must be turned clockwise to loosen).

6. 6

   Install new clutch

   Install the new viscous fan clutch assembly and torque to OEM specifications.

7. 7

   Reattach fan blades

   Reattach the fan blades to the new clutch and reinstall the fan shroud.

8. 8

   Reconnect electrical

   Reconnect the electrical connector and the battery.

9. 9

   Clear fault code

   Clear the ENG 245 fault code using a diagnostic scan tool, start the tractor, and verify that the fan engages properly as engine temperatures rise and that the code does not return.
