2024-2025 Hyundai Display Screen Flickering TSB

Owners of certain 2024-2025 Hyundai Santa Cruz, Santa Fe, Santa Fe Hybrid, and Tucson vehicles may experience their display screen flickering or intermittently going blank. This issue, detailed in Hyundai Technical Service Bulletin (TSB) 24-BE-007H-1, is attributed to a loose connection caused by the coaxial cable shield being too wide.

This TSB, issued in November 2024, supersedes the previous bulletin 24-BE-007H. It provides a specific repair procedure to adjust the coaxial cable shield using a specialized tool, ensuring a more secure connection and resolving the Hyundai display screen flickering problem.

Symptoms

Owners may observe the following issues with their vehicle's display screen:

• Display screen flickering
• Display screen intermittently going blank

Diagnosis

The root cause of the Hyundai display screen flickering or going blank is identified as the coaxial cable shield being too wide. This excessive width prevents a secure connection, leading to intermittent signal loss and the observed display issues. Technicians will inspect the coaxial cable connection to confirm this condition.

Repair Procedure Summary

The repair outlined in TSB 24-BE-007H-1 involves adjusting the width of the coaxial cable shield to ensure a proper connection. The general steps are:

1. Disconnect Battery: The ignition switch is turned off, and the negative battery terminal is disconnected for safety.
2. Access Monitor Assembly: The integrated monitor assembly is carefully removed from the dashboard, following specific shop manual procedures for each model (Santa Fe/Santa Fe Hybrid, Santa Cruz, Tucson).
3. Locate Connector: The relevant coaxial cable connector (e.g., M09A, M12, M22-A, M10-A) is accessed.
4. Remove Coaxial Cable: The yellow lock on the connector is disengaged, and the coaxial cable is removed from its terminal.
5. Adjust Coaxial Cable Shield: A specialized shield adjustment jig (part number SVCTBUJIG) is used. The end of the coaxial cable is inserted into the jig at an angle, gently rotated to allow the shield to enter, and then inserted fully to a minimum depth of 1 mm and a maximum depth of 3 mm. The jig is then rotated three times around the shield to reduce its width.
6. Reassembly and Verification: The coaxial cable is reinserted into the connector, and all removed components are reassembled in reverse order. The ignition is turned on to verify that the display screen no longer exhibits flickering or intermittent blanking.

Required Tools or Parts

The primary special tool required for this repair is:

• Shield Adjustment Jig (SVCTBUJIG): Each dealership should have been previously supplied with one jig. If an additional jig is needed, the MPA Parts Help Desk must be contacted at 844-436-6455, with a reason provided for the additional request.

Additionally, specific causal part numbers are used for warranty claims, including 91100-R6250, 91100-HB060, 91100-CW530, and 91100-K5860, depending on the vehicle model.

Important Notes for Owners

• Warranty Claims: If any part requires replacement during this TSB procedure and is still under warranty, a separate claim should be submitted. For parts out of warranty, a Prior Approval request for goodwill consideration is necessary before proceeding with the work.
• Repair Validation: Technicians are required to take repair validation photos, including the last 6 digits of the VIN and the repair date, which must be uploaded to the STUI system.

Owner Action

If you are experiencing a Hyundai display screen flickering or intermittently going blank in your 2024-2025 Hyundai Santa Cruz, Santa Fe, Santa Fe Hybrid, or Tucson, you should schedule an appointment with your authorized Hyundai dealership. They will perform the inspection and necessary coaxial cable shield adjustment as outlined in TSB 24-BE-007H-1.
