The ODBII code U1319 indicates that there is invalid or missing data related to the vehicle speed, which may affect the performance of various systems that rely on this information.

The severity of ODBII code U1319 is moderate.

Common Causes For: U1318 Lost Communication with Body Control Module (BCM)”.

  • Faulty vehicle speed sensor
  • Damaged wiring or connectors
  • Poor ground connection
  • Malfunctioning engine control module (ECM)
  • Issues with the transmission control module (TCM)
  • Faulty ABS module
  • Corrupted data communication between modules
  • Software glitches or updates needed in the ECM/TCM

Common misdiagnosis for U1319 Invalid or Missing Data for Vehicle Speed.

  • Faulty Vehicle Speed Sensor (VSS)
  • Malfunctioning Engine Control Module (ECM)
  • Wiring issues or short circuits in the speed sensor circuit
  • Problems with the ABS module
  • Incorrect tire size or calibration issues
  • Transmission issues
  • Faulty wheel speed sensors
  • Issues with the instrument cluster or dashboard display

Common Troubleshooting Steps

The OBD-II code U1319 indicates an “Invalid or Missing Data for Vehicle Speed.” This code typically relates to issues with the communication between the vehicle’s control modules, particularly concerning the vehicle speed data. Here are some common troubleshooting steps to diagnose and resolve this issue:

  • Check for Other Codes: Use an OBD-II scanner to check for any other trouble codes that may be present. Sometimes, multiple codes can provide more context for the issue.
  • Inspect Wiring and Connectors: Examine the wiring and connectors related to the vehicle speed sensor (VSS) and the modules that communicate vehicle speed data. Look for signs of damage, corrosion, or loose connections.
  • Test the Vehicle Speed Sensor (VSS): The VSS is responsible for sending speed data to the engine control module (ECM) and other systems. Test the VSS for proper operation using a multimeter or scan tool. If the sensor is faulty, it may need to be replaced.
  • Check the ECM/PCM: Ensure that the engine control module (ECM) or powertrain control module (PCM) is functioning correctly. If there are issues with the module itself, it may not process or communicate the vehicle speed data properly.
  • Inspect the ABS Module: In some vehicles, the ABS (Anti-lock Braking System) module also plays a role in vehicle speed data. Check for any faults in the ABS system and ensure it is functioning correctly.
  • Look for Ground Issues: Ensure that all ground connections related to the VSS and control modules are secure and free of corrosion. Poor grounding can lead to communication issues.
  • Check for Software Updates: Sometimes, a software update for the ECM or other control modules can resolve communication issues. Check with the manufacturer for any available updates.
  • Perform a System Reset: After addressing any identified issues, clear the trouble codes using the OBD-II scanner and take the vehicle for a test drive to see if the code returns.
  • Consult Technical Service Bulletins (TSBs): Check for any TSBs related to the U1319 code for your specific vehicle make and model. Manufacturers may have issued guidance on common issues and fixes.
  • Professional Diagnosis: If the problem persists after performing these steps, consider seeking help from a professional mechanic or dealership. They may have access to specialized diagnostic tools and knowledge of specific vehicle issues. By following these steps, you should be able to identify and resolve the underlying issue causing the U1319 code.
