Case IH 4309 – EHR (Electronic Hitch/Remote): Rear Remote No. 6 - Open Center Position Not Reached

The spool inside the rear remote control valve No. 6 has failed to reach the open center (or float) position. This indicates that the valve spool is physically unable to return to neutral/open center, which is typically caused by either incorrect hydraulic pressure in the system or a mechanical/electrical failure within the EHR valve itself.

1. 1

   Check the EHR module for any other active error codes

2. 2

   Make a note of all codes, clear them using an electronic service tool, and test the hydraulic system for normal operation

3. 3

   Verify that the tractor's overall hydraulic pressure is correct and within OEM specifications

2. 2

   Cycle the rear remote No. 6 switch in the cab to see if the spool will actuate and return to the open center position.

3. 3

   Hook up a hydraulic pressure gauge to the tractor's test port to verify standby and working hydraulic pressures.

   Hook up a hydraulic pressure gauge to the tractor's test port to verify standby and working hydraulic pressures. Incorrect pressure can prevent the spool from centering.

4. 4

   If the hydraulic pressure is correct but the 4309 code persists, the EHR valve for remote No. 6 is internally faulty.

5. 5

   Relieve all hydraulic pressure from the system.

7. 7

   Install a replacement EHR valve, re-torque the stack tie-rods to spec, and recalibrate the remotes using the tractor's display or service tool.
