Description:

This diagnostic trouble code is generated when there is a data transfer problem between the PTA control software and the TIA control software. Intermittent or non-existent reception of messages sent on the CAN BUS by the TIA 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 TIA Software:

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

Note:

Maintaining reliable communication over the CAN BUS is crucial for the proper operation of the control software. Regular checks and maintenance of the CAN BUS system can help prevent communication issues and ensure smooth vehicle performance.
