Case IH 5 1 – Hitch Controller: Right Draft Pin Failure

The system has detected an abnormal voltage reading or an open/short circuit from the right-hand load pin sensor, which disables the draft sensing function and can prevent the hitch from raising or operating properly.

1. 1

   Check the Hitch Controller Diagnostics to view the 'r offset' (the count number of the no-load voltage reading on the right load pin). A reading outside the normal baseline indicates a failed sensor or wiring issue.

2. 2

   Visually inspect the wiring harness and the plastic weather connectors leading to the right draft pin. Look for pinched wires, corrosion, or moisture inside the connector that could cause a short or open circuit.

3. 3

   Test the load pin sensor itself. If the wiring is intact and the connector is clean, the load pin has likely failed internally.

1. 1

   Lower the hitch and turn off the tractor

   Option A (Install Elimination Kit): Lower the hitch to the ground and turn off the tractor.

2. 2

   Locate wiring harness connectors

   Option A: Locate the wiring harness connectors for both the left and right draft load pins.

3. 3

   Disconnect factory wiring harness

   Option A: Disconnect the factory wiring harness from the defective load pins.

4. 4

   Plug in elimination modules

   Option A: Plug the two Electronic Load Sensing Elimination Modules directly into the tractor's wiring harness.

5. 5

   Secure modules and wiring

   Option A: Secure the modules and wiring safely out of the way using the provided tie wraps.

6. 6

   Restart the tractor

   Option A: Restart the tractor; the diagnostic system will no longer detect the pins, the code will clear, and draft sensing will be permanently disabled.

7. 7

   Lower the hitch to the ground

   Option B (Replace Right Load Pin): Lower the hitch to the ground to remove all mechanical tension from the lower links.

8. 8

   Disconnect wiring harness

   Option B: Disconnect the wiring harness from the right load pin.

9. 9

   Remove retaining hardware

   Option B: Remove the retaining hardware (snap rings or retaining bolts) holding the right draft pin in the hitch casting.

10. 10

    Remove old load pin

    Option B: Drive the old load pin out of the lower link arm.

11. 11

    Install new load pin

    Option B: Clean the bore, install the new OEM load pin, and secure it with the retaining hardware.

12. 12

    Reconnect wiring harness

    Option B: Reconnect the wiring harness.

13. 13

    Perform hitch calibration

    Option B: Perform a hitch calibration procedure via the tractor's instrumentation to zero out the new load pin's reference voltage.
