2022 Hyundai Tucson Volume Unavailability Software Update TSB

Hyundai has released Technical Service Bulletin (TSB) 23-01-028H to address a specific audio system concern in certain 2022 Hyundai Tucson (NX4) vehicles. This bulletin details a software update for the D-Audio system to correct instances where the Bluelink or Bluetooth volume becomes unavailable. This TSB supersedes TSB 22-01-077H, providing updated instructions for downloading the necessary software.

Symptoms

Owners of affected 2022 Hyundai Tucson vehicles may experience a condition where the Bluelink or Bluetooth audio volume is unavailable. This means that audio from these sources cannot be heard or adjusted, impacting communication and entertainment functionalities.

Important Warnings for Owners and Technicians

• Dealers are required to perform Service Campaign T9D whenever an affected vehicle is brought in for any maintenance or repair.
• To prevent a battery drain during the update, ensure the vehicle's battery is sufficiently charged and the power is switched to "On."
• Do not remove the USB memory stick or turn off the ignition switch during the update. Doing so will prevent the update from completing successfully and could lead to data loss or system malfunction.
• All warranty claims submitted for this service that include an illegible, incomplete, missing, or incorrect picture (referring to the STUI requirement for VIN and software version photos) are subject to debit.

Software Update Details

The TSB specifies a D-Audio software update to resolve the Hyundai Tucson volume unavailability. The software version before the update is NX4.USA.D2V.002.001.210901. After the update, the software version should be NX4.USA.D2V.003.100.220331 or newer.

Repair Procedure Summary

The repair involves updating the D-Audio system software using a USB memory stick. The general procedure is as follows:

1. Verify Current Software Version: Technicians will turn on the vehicle and navigate to the head unit's settings menu to check the current software version. If the installed software is older than NX4.USA.D2V.003.100.220331, the update proceeds.
2. Insert USB Memory Stick: A USB memory stick containing the update software (Part Number 96160-DAV2) is inserted into the vehicle's USB port. If the previously supplied memory stick is unavailable, instructions are provided to download the software from the Hyundai update website onto a new USB stick.
3. Initiate Update: The system will detect the USB and prompt to start the update. The update process takes approximately 15 minutes, during which the display may show the Hyundai logo or go black multiple times. It is crucial not to interrupt this process.
4. Verify Update: After the system restarts, the technician will confirm that the software has been successfully updated to the new version by checking the SW Info/Update screen.
5. Documentation: A picture of the VIN plate and the updated software version screen on the head unit must be taken and uploaded to STUI for warranty claim purposes.

Required Tools or Parts

• S/W UPDATE USB MEMORY STICK: Part Number 96160-DAV2. One USB stick is shipped to each Hyundai dealership. If unavailable, the software can be downloaded.
• Causal Part: 96160-N9480 is identified as the causal part for warranty claims under operation code 20D076R0.
