2024-2025 Hyundai Bluelink Connectivity Loss TSB 25-01-018H

Important Warnings for Owners

Hyundai Service Campaign 9C0 (TSB 25-01-018H) is a critical update for affected vehicles. Dealers are required to perform this service campaign on all impacted vehicles before customer retail delivery and whenever an affected vehicle is brought in for any maintenance or repair.

Owners of affected IONIQ vehicles should note that repairs must be performed at IONIQ certified dealers to prevent any potential damage.

Symptoms of Bluelink Connectivity Loss

Owners of certain 2024-2025 Hyundai models may notice a Hyundai Bluelink connectivity loss or interruptions in the middle of using Bluelink functions. This can manifest as a complete loss of connection or intermittent service disruptions, impacting features that rely on the Bluelink system.

Why This Happens

The primary cause for this Hyundai Bluelink connectivity loss is identified as an occasional disconnection on Verizon's communication network, which affects the vehicle's Bluelink Data Communication Unit (DCU). This service campaign aims to address this by verifying the DCU network connection and, if necessary, resetting the DCU in Dealer Mode.

Repair Procedure Summary

The repair procedure involves two main stages: an initial verification of the Bluelink connection and, if needed, a reset of the DCU network. The process begins by turning on the ignition and navigating through the infotainment system to the Bluelink settings. Technicians will attempt to activate or reconfigure Bluelink. If the message "Bluelink has been activated" appears, the initial verification is complete.

If Bluelink does not activate, the technician proceeds to reset the DCU network. This involves entering a special "Dealer Mode" within the infotainment system. Once in Dealer Mode, the technician selects "Connected Car Service" and then initiates a "Reset Network" command. After the reset, the system is re-verified to ensure Bluelink activation. If the DCU does not reset and Bluelink does not show as activated, technicians are instructed to contact Hyundai Techline.

Required Information for Repair

To access the necessary diagnostic and reset functions, technicians must enter a password to activate "Dealer Mode" in the vehicle's infotainment system. The password required for this procedure is 2400, which applies to all models.
