Description:

Error code ECU 001075.09 indicates a data transfer problem between the ECU and the fuel pump, where CAN Bus messages from the fuel pump cannot be received. This issue can result in improper fuel pump operation and potential engine performance problems.

Reaction:

The ECU may limit engine performance to prevent potential damage due to improper fuel pump operation.

Recommendations:

• Inspect CAN Bus Wiring and Connectors: Check the wiring and connectors in the CAN Bus network between the ECU and the fuel pump for signs of damage, corrosion, or loose connections.
• Verify CAN Bus Communication: Use diagnostic tools to verify the integrity of the CAN Bus communication system and ensure proper data transmission.
• Check for Interference: Ensure there are no sources of electromagnetic interference affecting the CAN Bus signals.
• Repair or Replace Faulty Components: Address any identified issues by repairing or replacing damaged wiring, connectors, or other components in the CAN Bus network.
• Test Fuel Pump Communication: After repairs, test the fuel pump to ensure it communicates correctly with the ECU and that CAN Bus messages are received properly.
• Reset ECU and Conduct System Tests: Reset the ECU to clear the error code and perform tests to confirm that the data transfer between the fuel pump and the ECU is functioning correctly.

Note:

Reliable CAN Bus communication is crucial for accurate data transfer between the ECU and the fuel pump, ensuring optimal fuel delivery and engine performance. Regular maintenance and timely repairs of the CAN Bus network can help prevent communication issues.
