PTA 002000.09 – Incorrect CAN BUS Message, Information from ECU Control Software

PTA 002000.09 (PTA 2000.09)

Code: 002000.09

Shortcode: 2000.09

Description:

This diagnostic trouble code is generated when there is a data transfer problem between the ECU control software and the PTA control software. Intermittent or non-existent reception of messages sent on the CAN BUS by the ECU control software indicates an open circuit, a short circuit, or faulty CAN BUS terminating resistors.

Reaction:

Limited or no function of the control software until the error is corrected, indicating a critical communication issue.

Recommendations:

Inspect CAN BUS Wiring:

  • Check the CAN BUS wiring for any signs of damage, wear, or disconnection.
  • Repair or replace any damaged wiring.

Test CAN BUS Terminating Resistors:

  • Verify the integrity and functionality of the CAN BUS terminating resistors.
  • Replace any faulty resistors.

Ensure Proper Connections:

  • Inspect all connectors associated with the CAN BUS for secure and proper connections.
  • Clean or replace any corroded or loose connectors.

Verify ECU Software:

  • Ensure the ECU control software is up to date and properly configured.
  • Update the software if necessary.

Note:

Reliable communication over the CAN BUS is essential for the proper functioning of the control software. Regular maintenance and prompt attention to any communication issues can help prevent significant operational disruptions.
