Description:

Error code ECU 001485.02 is triggered when the ECU detects an internal feedback error from the main ECU relay. This error indicates a malfunction in the feedback circuit or a failure in the relay itself, potentially affecting the overall operation of the engine control unit.

Reaction:

The ECU may limit engine performance or other subsystem operations to prevent potential damage due to unreliable relay function.

Recommendations:

• Inspect Main ECU Relay and Wiring: Check the main ECU relay and its associated wiring for signs of damage, corrosion, or loose connections that could disrupt feedback signals.
• Test Relay Functionality: Use diagnostic tools to test the main ECU relay’s operation to ensure it is functioning correctly and providing accurate feedback to the ECU.
• Check for Electrical Faults: Inspect the electrical circuit for any faults that could affect the relay’s feedback mechanism.
• Replace Faulty Relay: If the main ECU relay is found to be defective, replace it with a new one to restore proper function and feedback to the ECU.
• Reset ECU and Verify Operation: After replacing the relay, reset the ECU to clear the error code and test the system to confirm that the relay operates correctly and no further errors are detected.

Note:

Regular inspection and timely maintenance of the main ECU relay and its circuits are crucial for ensuring the reliability and proper function of the engine control unit.
