John Deere 522011.19 – PTF, RPT, or OIC: CAN BUS Message Issue With Communication Between the Cab Module and Front Chassis Module (PTF)

Data transfer problem where the receiving module intermittently or completely fails to receive one, several, or all of the expected CAN messages from the Operator Information Center (OIC). This is typically caused by a loose wire, poor connection, or outdated transmitting control software.

1. 1

   Test CAN Bus Communication: Use John Deere diagnostic tools to test the CAN bus communication for any irregularities or failures.

2. 2

   Verify Message Transmission: Ensure that all CAN messages are being correctly transmitted and received between the OIC control software and the RPT/PTF control software.

3. 3

   Inspect Wiring and Connections: Because intermittent reception issues on the CAN bus are often caused by loose wires or poor connections, thoroughly inspect the wiring harness between the cab and the front chassis.

4. 4

   Check Software Versions: Verify that the software on the OIC, RPT, and PTF modules is up-to-date, as software updates can mitigate many communication-related problems.

1. 1

   Visual Inspection

   Inspect the CAN bus wiring harness and connectors routing from the Operator Information Center (Cab Module) to the Front Chassis Module (PTF) and Main Control Module (RPT).

2. 2

   Repair Connections

   Secure any loose connections and repair or replace any damaged wires causing intermittent communication drops.

3. 3

   Software Update

   If the wiring is intact, connect the machine to the dealer diagnostic tool and flash the OIC, PTF, and RPT modules with the latest control software.

4. 4

   Clear and Retest

   Clear the 522011.19 fault code and operate the tractor to ensure the CAN bus communication is restored and the code does not return.
