Description:

This error code, TID 002071.09, is triggered when the control software detects a data transfer issue between the TID control software and the CCU control software. The intermittent or non-existent reception of messages from the CCU control software suggests an open circuit in the CAN bus line, a short circuit, or faulty CAN bus terminating resistors.

Reaction:

The control software may limit or completely disable transmission functions when this error is detected, leading to reduced vehicle performance and functionality.

Recommendations:

• Inspect CAN Bus Wiring: Examine the CAN bus wiring for damage, loose connections, or corrosion. Repair or replace any compromised wiring.
• Check for Open Circuit: Use diagnostic tools to test for open circuits in the CAN bus line. Ensure that all connections are secure and continuous.
• Inspect for Short Circuit: Look for any signs of a short circuit in the CAN bus wiring. Ensure all wires are properly insulated and not exposed.
• Verify CAN Bus Terminating Resistors: Check the CAN bus terminating resistors for proper installation and functionality. Replace any that are faulty.
• Update CCU Control Software: Ensure the CCU control software is updated to the latest version to prevent any software-related communication problems.

Note:

Maintaining the CAN bus system’s health is crucial for reliable communication and performance. Regular inspections and prompt resolution of any issues with wiring or resistors are essential for ensuring proper vehicle operation.
