Description:

This error code is generated when the PTP control unit does not receive CAN messages from the ECU. This can indicate a communication issue between the PTP and the ECU.

Reaction:

The control unit limits functionality to prevent potential issues due to missing ECU data.

Recommendations:

• Check CAN Bus Connections:
  Inspect the CAN bus wiring and connectors between the PTP and ECU for any signs of damage, loose connections, or corrosion. Repair or replace as necessary.
• Verify ECU Function:
  Ensure that the ECU is powered on and functioning correctly. Check for any ECU-related error codes.
• Test Communication:
  Use diagnostic tools to test the CAN bus communication between the PTP and ECU. Ensure that messages are being transmitted and received correctly.
• Consult Technical Support:
  If the issue persists, consult technical support or the manufacturer for further assistance.

Note:

Reliable communication between the PTP and ECU is essential for proper vehicle operation. Regular maintenance of the CAN bus system can help prevent communication issues.
