Description:

This error code, TID 002000.09, is generated when the control software detects a data transfer problem between the ECU control software and the TID control software. The issue is characterized by intermittent or non-existent reception of messages sent on the CAN BUS by the ECU control software. This typically indicates an open circuit in the CAN bus, a short circuit, or faulty CAN bus terminators.

Reaction:

When this error occurs, the control software may limit or completely disable the transmission functions, affecting the vehicle’s performance and operation.

Recommendations:

• Inspect CAN Bus Wiring: Check the CAN bus wiring for any signs of damage, loose connections, or corrosion. Repair or replace any damaged wiring.
• Check for Open Circuit: Use a multimeter to test for an open circuit in the CAN bus. Ensure all connections are secure and continuous.
• Inspect for Short Circuit: Look for any signs of a short circuit in the CAN bus wiring. Ensure that there are no exposed wires that could be causing a short.
• Verify CAN Bus Terminators: Check the CAN bus terminators to ensure they are functioning correctly and are properly installed. Replace any faulty terminators.
• Update ECU Control Software: Ensure that the ECU control software is up-to-date with the latest version to mitigate any software-related communication issues.

Note:

Regular inspection and maintenance of the CAN bus system are crucial for preventing data transfer issues. Ensuring all components are in good condition and properly connected helps maintain reliable communication between control software systems.
