Troubleshooting a Malfunctioning Speedometer in a 2020-present Toyota Highlander (XU70)
Repair Instructions

  1. Replace the Vehicle Speed Sensor (if needed)

    • Remove the old VSS by unscrewing any bolts holding it in place.
    • Install the new VSS and secure it with the appropriate fasteners.
    • Reconnect the wiring harness.

  2. Repair or Replace Wiring/Connectors (if needed)

    • If damaged wires or connectors were found, repair the wiring by either soldering or replacing the damaged sections.
    • Ensure all connections are secure and insulated to prevent future issues.

  3. Reinstall Instrument Cluster (if inspected)

    • If the instrument cluster was removed for inspection, reattach it securely, ensuring all connectors are plugged in correctly.
    • Reinstall any panels or trim pieces removed during the process.

  4. Clear Codes and Test Drive

    • Use the OBD-II scanner to clear any trouble codes stored in the system.
    • Take the vehicle for a test drive to ensure that the speedometer operates correctly at various speeds.

  5. Final Checks

    • After the test drive, re-check for any DTCs and confirm that the speedometer is functioning as expected.
Conclusion

If after following these steps the speedometer is still malfunctioning, it may be necessary to consult a professional technician or consider replacing the entire instrument cluster. Always refer to the vehicle’s service manual for specific repair instructions and specifications.
