Description:

This code indicates that the engine speed data is either missing or has an abnormal update rate over the CAN network. This could be due to communication issues within the network, sensor problems, or faults in the engine control module.

Reaction:

The engine control system may not receive accurate speed data, potentially affecting engine performance and triggering a warning light on the dashboard.

Recommendations:

• Inspect CAN Network Wiring:
  • Check the CAN network wiring for damage or loose connections.
  • Ensure all connectors are properly seated and free from corrosion.
• Test Engine Speed Sensor:
  • Verify that the engine speed sensor is functioning correctly and transmitting data at the correct rate.
  • Replace the sensor if it is faulty.
• Check ECU and Network Modules:
  • Ensure the ECU and other network modules are functioning correctly and up to date.
  • Update software and firmware to the latest versions.
• Verify Data Integrity:
  • Use diagnostic tools to check the integrity and update rate of data being transmitted over the CAN network.

Note:

Maintaining a healthy CAN network and ensuring all components are functioning correctly can help prevent issues with data transmission rates.
