2022-2025 Alfa Romeo, Dodge Uconnect Box Service Message

Owners of certain 2022-2025 Alfa Romeo and Dodge vehicles may encounter an intermittent or random "Uconnect Box Requires Service" error message displayed on their radio screen. This issue, documented in Stellantis TSB S2508000101, is linked to specific diagnostic trouble codes (DTCs) within the Telematics Box Module (TBM).

This technical service bulletin, released in November 2025, provides crucial information regarding the cause and upcoming resolution for the persistent "Uconnect Box Requires Service Message". It's important for owners to understand the underlying cause and the recommended actions.

Symptoms

The primary symptom owners will notice is an intermittent or random "Uconnect Box Requires Service" error popup message appearing on the vehicle's radio screen. This message indicates a potential issue with the vehicle's telematics system.

Fault Codes / DTCs

When a vehicle experiencing the "Uconnect Box Requires Service Message" is scanned for diagnostic trouble codes, technicians may find one or more of the following DTCs stored in the Telematics Box Module (TBM):

Code	Description
B22A9-96	ECU internal performance-component internal failure
B1560-11	Cellular antenna 1 short to ground
B1561-11	Cellular antenna 2 short to ground
B1562-14	GPS antenna short to ground or open

Diagnosis and Trigger Conditions

The root cause of this concern is identified as Telematics Box Module (TBM) software that has an improper DTC maturation time. This software anomaly leads to the intermittent triggering of the diagnostic trouble codes listed above, which in turn causes the "Uconnect Box Requires Service Message" to appear.

Important Warnings for Owners and Technicians

Stellantis TSB S2508000101 includes critical instructions regarding the diagnosis and repair of this issue:

• "If these DTCs are Stored or Pending, DO NOT REPLACE TBM. If DTCs are Active, follow DTC diagnostic procedures."
• "Do not replace the TBM for Stored or Pending DTCs, replacement TBMs will have the same software and issue."
• "Do not replace TBM unless DTC diagnostics lead to replacement."

These warnings emphasize that replacing the Telematics Box Module (TBM) is generally not the solution for stored or pending fault codes related to the "Uconnect Box Requires Service Message", as new modules would likely exhibit the same software-related problem.

Repair Procedure Summary

Engineering is currently developing a software update for the Telematics Box Module (TBM) to address the improper DTC maturation time responsible for the "Uconnect Box Requires Service Message" and associated DTCs (B22A9, B1560, B1561, B1562). This update is tentatively scheduled for release by Q2 2026. The software changes will specifically modify the maturation time for the intermittent Uconnect error message.

What Owners Should Do

If your 2022-2025 Alfa Romeo or Dodge vehicle displays the "Uconnect Box Requires Service Message", it is important to be aware of this known issue and the upcoming software update. Do not immediately assume a hardware failure of the Telematics Box Module (TBM).

If the message is intermittent and the DTCs are stored or pending, TBM replacement is not recommended. If the message is persistent or if active DTCs are present, contact your authorized Stellantis dealer for diagnosis. Inform them of TSB S2508000101 and the guidance against premature TBM replacement for stored/pending codes.
