Description:

This error code, TID 002003.09, is triggered when the control software detects a data transfer problem between the PTD 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 PTD control software. This typically indicates an open circuit in the CAN bus, a short circuit, or faulty CAN bus terminators.

Reaction:

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

Recommendations:

• Inspect CAN Bus Wiring: Examine the CAN bus wiring for any damage, loose connections, or corrosion. Repair or replace any compromised wiring.
• Check for Open Circuit: Use diagnostic tools to test for an open circuit in the CAN bus. Ensure all connections are secure and uninterrupted.
• Inspect for Short Circuit: Look for any evidence of a short circuit in the CAN bus wiring. Ensure that all wires are properly insulated and not exposed.
• Verify CAN Bus Terminators: Check the condition and installation of the CAN bus terminators. Replace any that are faulty or improperly installed.
• Update PTD Control Software: Ensure the PTD control software is updated to the latest version to prevent any software-related communication problems.

Note:

Maintaining the integrity of the CAN bus system is essential for reliable vehicle operation. Regular checks and prompt addressing of any wiring or terminator issues can prevent data transfer problems and ensure smooth communication between control software systems.
