New Holland 4143 – EHR: Rear Remote 4 Control Message Not Plausible

The Electronic Hitch Control (EHR) module has detected a data conflict on the CAN bus network, receiving an illogical or unexpected message from the components controlling the number four rear remote hydraulic valve. This indicates an issue with communication or signal integrity, such as incorrect voltage signals, corrupted data packets, or a loss of communication between the operator's controls and the valve.

1. 1

   Check for other related fault codes (such as 4144, 4146, 4147, or 4153) that can help pinpoint the issue

2. 2

   Inspect electrical connections for loose or corroded connectors at the number 4 remote valve and along the wiring harness

3. 3

   Check hydraulic fluid levels and condition, as low or contaminated fluid can cause erratic hydraulic behavior

4. 4

   Restart the tractor or toggle the master switch to see if an intermittent electrical fault clears

5. 5

   If accessible, swap the electronic module from the faulty remote valve with a known working one from another remote to determine if the module has failed

1. 1

   Perform diagnostic checks

   Complete the diagnostic steps listed above to rule out simple issues.

2. 2

   Inspect wiring harness

   Carefully inspect the wiring harness for the number 4 remote for any signs of damage, such as chafing, breaks, or corrosion. Repair any damaged sections.

3. 3

   Test valve components

   If the wiring is intact, test the electronic components of the valve (such as the control module or potentiometer). This may require using the New Holland Electronic Service Tool to read live data.

4. 4

   Calibrate the remote valve

   Recalibrate the remote valve through the tractor's diagnostic menu (often the 'H' menu). This procedure may require a special tool to connect to the valve block.

5. 5

   Replace faulty components

   If testing identifies the valve's electronic control module or potentiometer as faulty, replace the affected component.
