RLC 000639.14 – Vehicle CAN Bus (500 kBd), Very High Error Rate
RLC 000639.14 (RLC 639.14)
Code: 000639.14
Shortcode: 639.14
Description:
This error code indicates that too many incorrect CAN bus messages are being received, pointing to a general problem with the connection to the vehicle CAN bus (500 kBd).
Reaction:
When this error is detected, the control software may experience limited or no functionality, affecting the performance or operation of specific electronic control systems within the equipment.
Recommendations:
- Inspect CAN Bus Network:
- Perform a thorough inspection of the CAN bus network for any physical damage, loose connections, or corrosion. Repair or replace any compromised components.
- Check for Electrical Interference:
- Ensure that there are no sources of electrical interference near the CAN bus network that could be causing communication errors.
- Verify Termination Resistors:
- Ensure that proper termination resistors are installed at both ends of the CAN bus network. Incorrect termination can lead to high error rates.
- Monitor CAN Bus Load:
- Check the CAN bus load to ensure it is not overloaded. Reduce the number of devices on the CAN bus if necessary.
- Update Control Software:
- Make sure the control software is updated to the latest version to fix any potential software-related issues.
Note:
A very high error rate on the CAN bus can severely impact the vehicle’s electronic systems. Prompt action to diagnose and resolve the issue is essential to maintain reliable operation.
