PTF 002139.09 (PTF 2139.09)

Code: 002139.09

Shortcode: 2139.09


This error code is generated when a data transfer problem occurs between the CSM control software and the PTF control software. The reception of one or more CAN messages transmitted by the CSM control software is intermittent or non-existent, which may be due to issues such as a loose wire. This indicates a problem in the CAN bus.


When this code is detected, the control software may exhibit limited or no functionality.


    • Inspect CAN Bus Connections:
      • Check all CAN bus connections for secure and correct installation.
      • Look for any damaged or corroded connectors and replace if necessary.
    • Verify Wiring Integrity:
      • Ensure all wires in the CAN bus network are intact and free of damage.
      • Repair or replace any loose or damaged wires.
    • Check CSM Software:
      • Ensure that the CSM control software is up to date.
      • Update the software if necessary.
    • Diagnose CAN Bus Traffic:
      • Use diagnostic tools to analyze CAN bus traffic and identify any abnormalities or faults.


Reliable CAN bus communication between the CSM and PTF control software is critical for proper operation. Regular inspections and maintenance can prevent data transfer problems.
