Massey Ferguson 00.2.70 – Dash Module: Dash Module Is Missing Information From The Linkage Module On The CAN BUS System (Dash)

The Dash Module (Instrument Panel) expects regular status updates from the Linkage Module (which controls the electronic 3-point hitch/linkage system). This code triggers when the Dash stops receiving these expected data packets, indicating a communication breakdown between the two modules.

1. 1

   Check for accompanying codes: If multiple modules are missing, the fault is likely the main CAN BUS line or the Dash itself. If 00.2.70 is the only code, the issue is isolated to the Linkage Module or its wiring.

2. 2

   Verify fuses and relays to ensure the Linkage Module is receiving proper power and ground.

3. 3

   Inspect CAN BUS connectors at the Linkage Module (under cab floor or near rear linkage) and behind the Dash for moisture, dirt, and corrosion.

4. 4

   Inspect the wiring harness for chafing, rodent damage, or breaks, particularly where the harness routes from the cab down to the rear linkage housing.

1. 1

   Disconnect the Battery

   Always disconnect the battery before working on the CAN BUS system to prevent voltage spikes.

2. 2

   Clean Connectors

   Locate the Linkage Module (usually mounted near the rear axle/linkage housing or under the rear cab floor). Disconnect the main wiring harness. Spray the pins with electrical contact cleaner. If moisture is present, dry it thoroughly and apply a light coating of dielectric grease (or Vaseline) to prevent water ingress.

3. 3

   Repair Wiring

   If any chafed or broken wires are found on the CAN High (CAN-H) or CAN Low (CAN-L) lines, splice and heat-shrink the repairs to ensure they are weatherproof.

4. 4

   Test Module Power

   Reconnect the battery and turn the key to the ON position. Use a multimeter to verify that the Linkage Module is receiving 12V power and has a solid ground.

5. 5

   Replace Module (If Necessary)

   If the wiring, power, and ground are all intact but the module still will not communicate, the Linkage Module has failed internally and must be replaced.

6. 6

   Clear Codes

   After repair, use a diagnostic tool to clear the fault codes and test the electronic linkage controls to ensure full functionality.
