Definition

The OBD2 code U1164 SCP (J1850) Invalid or Missing Data for Tuner/Receiver indicates that the vehicle's communication network is not receiving valid data from the tuner or audio receiver module, which may affect audio system functionality

Common causes

  • Faulty tuner/receiver module
  • Poor or damaged wiring/connectors
  • Corrupted software or firmware in the tuner/receiver
  • Communication issues between modules
  • Low battery voltage or power supply issues
  • Faulty or disconnected antenna
  • Interference from other electronic devices
  • Grounding issues in the vehicle's electrical system

Common misdiagnoses

  • Faulty tuner/receiver
  • Wiring issues or shorts
  • Poor ground connections
  • Faulty vehicle communication network (CAN bus)
  • Malfunctioning body control module (BCM)
  • Incorrectly programmed or incompatible aftermarket radio
  • Software glitches in the audio system
  • Faulty antenna or signal issues

Troubleshooting steps

  1. 1. Check for Additional 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

  2. 2. Inspect Wiring and Connectors

    Visual Inspection: Check the wiring and connectors related to the tuner/receiver for any signs of damage, corrosion, or loose connections

  3. 3. Connector Pins

    Ensure that the pins in the connectors are not bent or corroded

  4. 4. Test the Tuner/Receiver

    If accessible, test the tuner/receiver unit itself. This may involve checking for power and ground at the unit

  5. 5. If possible, swap the tuner/receiver with a known good unit to see if the problem persists

  6. 6. Check for Communication Issues

    Use a scan tool to monitor the communication on the J1850 bus. Look for any irregularities in data transmission

  7. 7. Ensure that there are no other devices on the bus that may be causing interference

  8. 8. Inspect the Vehicle’s Electrical System

    Check the vehicle’s battery and charging system. Low voltage can cause communication issues

  9. 9. Inspect fuses related to the audio system and communication modules

  10. 10. Update or Reprogram Modules

    In some cases, the issue may be resolved by updating or reprogramming the vehicle’s modules. Check with the manufacturer for any available updates

  11. 11. Perform a Hard Reset

    Disconnect the vehicle’s battery for a few minutes to reset the modules. Reconnect and see if the code reappears

  12. 12. Check for Software Issues

    If the vehicle has had recent software updates or modifications, ensure that they were performed correctly and are compatible with the vehicle’s systems

  13. 13. Consult Technical Service Bulletins (TSBs)

    Look for any TSBs related to the specific make and model of the vehicle. Manufacturers may have issued guidance on common issues related to the U1164 code

  14. 14. Professional Diagnosis

    If the issue persists after performing the above steps, consider seeking help from a professional technician or dealership. They may have specialized tools and knowledge to diagnose complex communication issues.Conclusion Troubleshooting OBD-II code U1164 involves a systematic approach to identify and resolve issues related to the tuner/receiver and its communication with the vehicle’s network. Always ensure safety and follow manufacturer guidelines when working on vehicle electronics
