PLC 000639.19 – Power Train CAN BUS, Very High Error Rate
PLC 000639.19 (PLC 639.19)
Code: 000639.19
Shortcode: 639.19
Description:
This diagnostic trouble code is generated when the control unit detects a very high error rate in the CAN BUS messages related to the power train. This indicates a severe issue with the CAN BUS communication network.
Reaction:
The equipment may experience significant performance issues, including erratic operation or failure of components that rely on CAN BUS communication. The system may enter a fail-safe mode to prevent further damage.
Recommendations:
- Inspect CAN BUS Network:
- Thoroughly check the CAN BUS wiring for any damage, corrosion, or loose connections. Repair or replace damaged sections.
- Verify Termination Resistors:
- Ensure termination resistors are correctly placed and functioning in the CAN BUS network to maintain proper signal integrity.
- Check for Electromagnetic Interference:
- Identify and mitigate sources of electromagnetic interference that may be affecting CAN BUS communication.
- Update Software:
- Ensure the control unit and other modules on the CAN BUS network have the latest software updates installed.
- Replace Faulty Components:
- Replace any identified faulty modules or control units to restore proper CAN BUS communication.
- Monitor CAN BUS Traffic:
- Use diagnostic tools to monitor CAN BUS traffic and identify specific nodes causing errors.
Note:
Maintaining the CAN BUS network’s integrity is critical for reliable system operation. Regular inspections and timely repairs are essential to prevent communication errors.
