New Holland 4101 – XCM: Rear Remote No.1 Control Message Not Plausible

The system has detected that the control message for the Rear Remote No.1 is not plausible, indicating an illogical or unexpected signal from the electronic control system of the number one rear hydraulic remote valve. This points to a communication problem over the CAN bus network between the operator's control (switch or lever) and the electronic valve block, or a fault within the valve's internal electronics and sensors.

1. 1

   Check battery and system voltage (must be above 12.6V) and ensure all main power and ground connections are clean and tight, as low voltage can cause ghost communication faults.

2. 2

   Visually inspect the wiring harness and connectors between the armrest controls, main tractor frame, and the No. 1 rear remote valve. Pay special attention to the plug located under the cab on the right-hand side above the battery for corrosion or damage.

3. 3

   Connect a diagnostic test switch (Special Tool 380000843 or similar) to the diagnostic port, often located on the rear right-hand pillar in the cab, to access the 'H' menu.

4. 4

   View and clear fault codes using the 'HB' and 'HC' menus, then operate the remote to see if code 4101 immediately returns.

5. 5

   Perform a switch test using the 'H5' menu to verify that the system recognizes the switch input from the rear remote #1 control.

6. 6

   Use the 'H9' menu for voltmeter diagnostics to check return voltages from sensors and switches for out-of-range signals.

1. 1

   Address basic electrical issues

   Repair any corroded connectors, damaged wires, or poor ground connections found during inspection. If system voltage is low, test and replace the battery or alternator as needed.

2. 2

   Isolate the fault

   Swap the electrical connector from the non-functional remote #1 with an adjacent working remote (e.g., remote #2). If the fault code changes to 4111 (Remote #2), the issue is likely the control handle or armrest controller. If 4101 remains, the problem is in the wiring to valve #1 or its electronic module.

3. 3

   Recalibrate remote valves

   Perform a calibration of the electronic remote valves through the 'H1' menu. If necessary, perform a non-volatile memory reset ('H8' menu) to erase old calibration values before recalibrating.

4. 4

   Replace faulty components

   If diagnostics and isolation steps point to a specific failure, replace the faulty control switch, wiring harness, or the complete rear remote valve assembly. The electronic module on top of the remote valve is a frequently cited point of failure.
