JDL 298883.31 – Vehicle CAN BUS, High Error Rate
JDL 298883.31 (JDL )
Code: 298883.31
Shortcode:
Description:
This diagnostic trouble code, JDL 298883.31, is generated when the control unit receives too many incorrect CAN BUS messages or detects a general problem in the connection to the vehicle CAN BUS. This indicates an issue with data transmission integrity on the CAN BUS network.
Reaction:
When this error code is triggered, the vehicle may experience communication issues between different control units, leading to erratic behavior, reduced functionality, or complete system failure.
Recommendations:
Inspect CAN BUS Wiring and Connectors:
- Check the CAN BUS wiring for any signs of damage, such as cuts, abrasions, or pinching.
- Ensure all connectors are properly seated and free of debris or corrosion.
Verify Termination Resistors:
- Check that the termination resistors at the ends of the CAN BUS network are present and within the correct resistance range (typically 120 ohms each).
Monitor CAN BUS Traffic:
- Use a CAN BUS analyzer tool to monitor the traffic on the CAN BUS network. Identify and address any anomalies or excessive error frames.
Update Control Unit Software:
- Ensure that the control unit software is up-to-date. Install any available updates to address known issues and improve communication stability.
Check for Electrical Interference:
- Inspect the vehicle for sources of electrical interference that could disrupt CAN BUS communication, such as high-power devices or poor grounding.
Consult Technical Support:
- If the issue persists after performing the above steps, consult the manufacturer’s technical support for further assistance.
- Provide the diagnostic trouble code and any relevant information gathered during the inspection.
Note:
High error rates on the CAN BUS can be caused by a variety of factors, including poor wiring practices, environmental conditions, or faulty components. Regular maintenance and inspection of the CAN BUS network can help prevent communication issues and ensure reliable operation of the vehicle’s systems.
