Massey Ferguson 00.01.44 – Dash Module: CAN BUS Message Issue (Dash)

This code indicates a communication failure on the Controller Area Network (CAN) bus system specifically related to the dashboard/instrument panel. The dash module is either failing to send or receive expected CAN messages to/from other control modules (such as the Engine ECU or Transmission controller).

1. 1

   Check for accompanying CAN BUS codes in the Engine or Transmission modules using a diagnostic scanner to rule out a main CAN backbone fault.

2. 2

   Check alternator and voltage regulator output with a multimeter to ensure voltage spikes or drops are not causing the dash to drop off the network.

3. 3

   Inspect main cab and dashboard fuses to ensure the instrument panel is receiving consistent power.

4. 4

   Inspect the wiring harness and connectors leading to the back of the instrument panel for damaged wires, corrosion, or loose connections.

5. 5

   Test the CAN High and CAN Low wires at the dash connector for proper resistance (typically 60 ohms across the network when powered down) to rule out an open or short circuit.

1. 1

   Disconnect Power

   Always disconnect the tractor's battery before working on the electrical system or removing control modules.

2. 2

   Remove Dash Cladding

   Carefully remove the steering column covers and instrument panel cladding/trim to access the mounting screws for the dash cluster.

3. 3

   Extract the Instrument Panel

   Unscrew the instrument panel and gently pull it forward.

4. 4

   Disconnect and Inspect

   Unplug the main wiring harness from the back of the dash. Inspect the pins on both the dash side and the harness side. Clean any corrosion with electrical contact cleaner.

5. 5

   Repair Wiring (If Applicable)

   If a broken wire or damaged pin is found in the CAN lines, repair the harness using OEM-grade heat-shrink connectors and re-pin the connector if necessary.

6. 6

   Repair or Replace the Dash (If Applicable)

   If the wiring is intact and power/ground are verified, the internal circuitry of the dash (such as damaged internal welds or a failed CAN transceiver) is likely at fault. The dash must either be sent to an agricultural electronics repair specialist (e.g., Repturn) or replaced entirely.

7. 7

   Reassembly

   Reconnect the wiring harness, mount the instrument panel, and reinstall the cladding.

8. 8

   Clear Codes

   Reconnect the battery, turn the key on, and use a diagnostic tool to clear the 00.01.44 fault code. Run the tractor to verify the code does not return and that all gauges function correctly.
