John Deere 2238.09 – PTF (Front Chassis Module): Incorrect CAN Bus Message, Information from SMV Control Software

A data transfer problem occurred between the SMV (Sequence Control Module) software and the PTF (Front Chassis Module) software. The reception of one or more CAN messages transmitted by the SMV control software is intermittent or non-existent, indicating a physical problem in the CAN bus network or a software/hardware issue with the transmitting control module.

1. 1

   Inspect CAN bus connections between the SMV and PTF modules for secure installation, backed-out pins, corrosion, or moisture damage

2. 2

   Verify CAN bus wiring harness integrity, looking for chafing, breaks, or loose wires (most common cause of intermittent messages)

3. 3

   Check software versions on both the SMV and PTF modules to ensure they are up to date and compatible

4. 4

   Diagnose CAN bus traffic using John Deere Service ADVISOR to verify if the SMV is broadcasting messages properly

1. 1

   Turn off the tractor and disconnect the battery

   Ensure safety while working on the electrical system.

2. 2

   Locate the SMV and PTF modules

   Locate the Sequence Control Module (SMV) and Front Chassis Module (PTF) on your specific tractor model.

3. 3

   Disconnect the wiring harnesses

   Disconnect the wiring harnesses from both modules.

4. 4

   Clean and inspect connectors

   Clean the connectors using electrical contact cleaner and inspect for any bent, pushed-back, or corroded pins.

5. 5

   Perform a continuity test

   Perform a continuity test on the CAN High and CAN Low wires between the SMV and PTF modules. Repair or replace the wiring harness if resistance is high or an open circuit is found.

6. 6

   Reconnect the harnesses

   Reconnect the harnesses securely.

7. 7

   Reconnect the battery and turn the key to the ON position

   Reconnect the battery and turn the key to the ON position.

8. 8

   Clear the fault code

   Connect a diagnostic tool (like John Deere Service ADVISOR) and clear the 002238.09 fault code.

9. 9

   Update software

   If the code returns immediately, update the software on the SMV and PTF modules.

10. 10

    Replace and reprogram modules

    If the wiring is intact and the software is updated but the code persists, the fault likely lies within the transmitting module (SMV) or receiving module (PTF). Module replacement and reprogramming by a dealer will be required.
