SIC 000639.14 – Vehicle CAN BUS, Very High Error Rate
SIC 000639.14 (SIC 639.14)
Code: 000639.14
Shortcode: 639.14
Description:
This error code, SIC 000639.14, is saved when the SIC control unit recognizes a very high error rate in the incoming CAN BUS messages. This indicates a general problem in the vehicle’s CAN BUS system, which could be due to electrical interference, faulty wiring, or a malfunctioning component.
Reaction:
When this error code is detected, communication between control units and other components may be disrupted, leading to erratic behavior, loss of functionality, or complete system failures.
Recommendations:
- Inspect CAN BUS Wiring:
- Check all CAN BUS wiring for signs of damage, wear, or corrosion. Repair or replace any compromised sections.
- Check Connectors:
- Ensure all connectors are properly seated and free from corrosion or debris.
- Test CAN BUS Components:
- Use diagnostic tools to test the CAN BUS network and identify faulty nodes or components.
- Shielding and Grounding:
- Verify that proper shielding and grounding techniques are in place to reduce electrical interference.
- Software Updates:
- Ensure that all control units on the CAN BUS network have up-to-date firmware and software.
Note:
High error rates on the CAN BUS can severely impact vehicle performance and safety. Regular inspection and maintenance of the CAN BUS network are essential to prevent such issues. If the problem persists, consult a professional technician for advanced diagnostics and repair.
