The ODBII code U2153: Instrument Cluster Communication Loss indicates a failure in communication between the instrument cluster and other control modules in the vehicle, which may affect the functionality of the dashboard displays and warning lights.

Moderate.

Common Causes For: U2152 SCP (J1850) Invalid Data from GEM

  • Faulty instrument cluster
  • Damaged wiring or connectors
  • Poor ground connections
  • Failed communication module
  • Corroded terminals
  • Software issues or glitches
  • Faulty CAN bus communication
  • Low battery voltage or power supply issues

Common misdiagnosis for U2153 U2153: Instrument Cluster Communication Loss

  • Faulty instrument cluster
  • Bad wiring or connectors
  • Defective body control module (BCM)
  • Malfunctioning engine control module (ECM)
  • Issues with the CAN bus system
  • Low battery voltage or poor battery connections
  • Faulty sensors or actuators
  • Software glitches or programming errors

Common Troubleshooting Steps

The OBD-II code U2153 indicates a communication loss with the instrument cluster. This can be caused by various issues, including wiring problems, module failures, or issues with the vehicle’s network. Here are some common troubleshooting steps to diagnose and resolve the U2153 code:

  • Check for Additional Codes: Use an OBD-II scanner to check for any other trouble codes that may be present. This can provide more context for the issue.
  • Inspect Wiring and Connectors: **Visual Inspection: Check the wiring harness and connectors related to the instrument cluster for any signs of damage, corrosion, or loose connections.
  • **Connector Pins: Ensure that the pins in the connectors are not bent or corroded.
  • Check Power and Ground: Verify that the instrument cluster is receiving the correct power supply and ground. Use a multimeter to check voltage and continuity.
  • Test the Instrument Cluster: If possible, test the instrument cluster itself. This may involve swapping it with a known good unit or using diagnostic tools to check its functionality.
  • Inspect the CAN Bus: The instrument cluster typically communicates over the Controller Area Network (CAN) bus. Check for any issues with the CAN bus wiring, including shorts or opens.
  • Use a CAN bus scanner to monitor communication between modules.
  • Check for Module Communication: Use a scan tool to check if other modules in the vehicle can communicate with the instrument cluster. If other modules are also having communication issues, it may indicate a broader network problem.
  • Look for Intermittent Issues: Sometimes, communication issues can be intermittent. Pay attention to when the code appears (e.g., after hitting a bump, during temperature changes) and check for any patterns.
  • Inspect Fuses: Check the fuses related to the instrument cluster and the communication network. Replace any blown fuses.
  • Software Updates: Check if there are any software updates available for the vehicle’s modules. Sometimes, updating the software can resolve communication issues.
  • Consult Technical Service Bulletins (TSBs): Look for any TSBs related to the U2153 code or instrument cluster issues for your specific vehicle make and model. Manufacturers may have specific fixes or recommendations.1
  • Professional Diagnosis: If the issue persists after performing the above steps, consider seeking help from a professional mechanic or dealership. They may have specialized tools and knowledge to diagnose complex communication issues.Conclusion Troubleshooting OBD-II code U2153 requires a systematic approach to identify the root cause of the communication loss. By following these steps, you can narrow down the potential issues and work towards a resolution.
