Case IH 1023 – Hitch (CCH or TCU): Two draft pin sensors failed when configured for two draft pins. (CCH Only)

The tractor's electronic draft control system is programmed to monitor two load-sensing draft pins on the 3-point hitch, but the controller has lost the signal from both sensors simultaneously.

1. 1

   Inspect the chassis wiring harness leading to the lower 3-point hitch draft pins for severed wires, abrasions, or pinch points

2. 2

   Disconnect the draft pin sensor connectors and inspect for moisture, corrosion, or pushed-out pins

3. 3

   Verify the tractor's software configuration to ensure it is not incorrectly expecting two pins when only one is utilized

1. 1

   Relieve hitch tension

   Park the tractor on a level surface and completely lower the 3-point hitch to the ground to relieve all mechanical tension and load on the lower link draft pins.

2. 2

   Disconnect power

   Turn off the engine and disconnect the battery ground.

3. 3

   Disconnect sensors

   Disconnect the electrical connectors from both left and right draft pin sensors.

4. 4

   Repair wiring

   If the wiring harness is damaged, repair the broken wires or replace the lower hitch harness section.

5. 5

   Remove retaining hardware

   If the wiring is intact and the sensors have failed internally, remove the retaining bolts/hardware holding the draft pins in the lower lift arms.

6. 6

   Remove faulty sensors

   Slide the faulty draft pin sensors out of the hitch linkage.

7. 7

   Install new sensors

   Install the new draft pin sensors (or a Draft Pin Elimination Kit) and secure them with the retaining hardware.

8. 8

   Reconnect electrical connectors

   Reconnect the electrical connectors.

9. 9

   Calibrate system

   Power on the tractor, clear the fault codes, and perform a Hydraulic Lift Autocalibration if required by the hitch control module.
