2024 Alfa Romeo Tonale Touch Screen Not Working TSB

Owners of 2024 Alfa Romeo Tonale vehicles may experience an unresponsive touch screen after a radio software update. This issue, identified by Technical Service Bulletin (TSB) 08-052-25, points to a software-related problem within the vehicle's Display Screen Module (DSM).

This bulletin, also released as Rapid Service Update (RSU) 25-022, provides a procedure for dealerships to update the DSM software to resolve the problem. It supersedes a previous bulletin, TSB 08-158-24, dated July 10, 2024.

Symptoms

If you own a 2024 Alfa Romeo Tonale, you might notice the following symptom:

• "Touch screen panel is not working properly after radio software update."

This symptom indicates that the Display Screen Module (DSM) may require a software update to restore full functionality.

Important Warnings for Owners

• Battery Voltage: During the software flash process, a battery charger must be installed to maintain battery voltage above 13.2 volts. The charging voltage must not exceed 13.5 volts to prevent damage.
• Interrupted Flash: If the software flash process is interrupted or aborted for any reason, it must be restarted from the beginning.
• Fuse Removal: A critical step in the repair involves removing fuse F81, which powers the Brake Booster Vacuum Pump. Failure to remove this fuse before the procedure can result in damage to the pump.

Diagnosis

When a 2024 Alfa Romeo Tonale exhibits the symptom of the touch screen not working, technicians will use a diagnostic tool like wiTECH. They will verify that all related systems are functioning correctly. If any Diagnostic Trouble Codes (DTCs) or other symptom conditions are present beyond the touch screen issue, these must be addressed and repaired first before proceeding with the DSM software update outlined in TSB 08-052-25.

Repair Procedure Summary

The repair procedure involves updating the software of the Display Screen Module (DSM). Here's a summary of the steps a technician will follow:

1. The technician will first check if the vehicle's VIN is listed for the Rapid Service Update (RSU) 25-022. If not, they will proceed based on the customer's reported symptom.
2. They will then determine if the DSM already has the latest software installed. If it does, the bulletin is considered complete. If not, they will proceed with the update.
3. Crucially, the green 30 Amp fuse from cavity F81, which supplies power to the Brake Booster Vacuum Pump, must be removed from the Power Distribution Center (PDC) in the engine compartment.
4. A wiTECH diagnostic tool is connected to the vehicle, and the ignition is placed in the “RUN” position.
5. The technician logs into the wiTECH 2.0 website, selects the vehicle, and navigates to the “Topology” tab to select the “DSM” module icon.
6. From the “Flash” tab, the current DSM software level is compared against the required “NEW PART NUMBER.” If an update is needed, the appropriate flash part number is selected.
7. The “Flash ECU” command is initiated, and the on-screen instructions are followed to complete the software flash.
8. After the flash, the software is confirmed to be at the latest calibration level, and any stored DTCs are cleared.
9. The ignition is cycled OFF and RUN to allow the system to reset.
10. Finally, fuse F81 is reinstalled, and the DSM's operational status is confirmed before the vehicle is returned to the customer.

Required Tools or Parts

• wiTECH or Equivalent: A specialized diagnostic tool is necessary to perform the software update.
