2023-2026 Jeep, RAM, Dodge Uconnect Box Service Message TSB

Owners of various 2023-2026 Jeep, RAM, and Dodge vehicles may encounter an intermittent "Uconnect Box Requires Service" message displayed on their radio screen. This issue, documented under Stellantis Technical Service Bulletin (TSB) S2508000100, is linked to specific diagnostic trouble codes (DTCs) within the Telematics Box Module (TBM).

This communication, released in November 2025, details the symptoms and provides crucial guidance for technicians regarding the diagnosis and repair of this condition. It's important for owners to understand the nature of this problem and the recommended actions.

Symptoms

The primary symptom owners will notice is an intermittent or random pop-up message on the vehicle's radio screen stating, "Uconnect Box Requires Service". This message indicates a potential issue with the vehicle's Uconnect system's telematics functionality.

Fault Codes / DTCs

When a vehicle exhibiting the "Uconnect Box Requires Service" message is scanned, one or more of the following Diagnostic Trouble Codes (DTCs) may be found stored or pending 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 / Trigger Conditions

The underlying cause of these DTCs and the intermittent "Uconnect Box Requires Service" message is believed to be related to the Telematics Box Module (TBM) software. Specifically, the TBM software may have an improper DTC maturation time, leading to these codes being set incorrectly or prematurely.

Important Warnings

Stellantis has issued critical instructions regarding the diagnosis and repair of this condition, particularly concerning the replacement of the Telematics Box Module (TBM):

• "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 TBM when the DTCs are merely stored or pending will not resolve the issue, as new TBMs currently contain the same software flaw. Replacement should only occur if standard diagnostic procedures confirm an active, hardware-related fault with the TBM.

Repair Procedure Summary

Stellantis engineering is actively developing a software update for the Telematics Box Module (TBM) to address the DTCs B22A9, B1560, B1561, and B1562, which are responsible for the "Uconnect Box Requires Service" message. This update is expected to include changes to the DTC maturation time, aiming to prevent the intermittent error messages from appearing.

What Owners Should Know

As of the TSB's release date (November 2025), the software update is still under development, with a tentative release date by Q2 2026. This means that a definitive fix for the intermittent Jeep Wrangler Uconnect Box Requires Service message is not yet available. Owners experiencing this issue should be aware that their dealership may not be able to provide an immediate software solution.

Given the instructions in TSB S2508000100, if your vehicle displays the "Uconnect Box Requires Service" message and a scan reveals these specific DTCs as stored or pending, the Telematics Box Module should not be replaced. Replacing the TBM prematurely will not fix the problem and could lead to unnecessary costs or delays. It is advisable to consult with your authorized dealership for the latest information regarding the availability of the TBM software update.
