2021-2024 Jeep/Dodge Uconnect TBM Firmware Update

Owners of certain 2021-2024 Jeep, Dodge, and Chrysler vehicles equipped with the Global Telematics Box Module (Sales Code RDG) may encounter a "Uconnect Box requires service" message displayed on their radio screen. This issue, along with other software enhancements, is addressed by Stellantis Technical Service Bulletin (TSB) 08-039-25, which details a Firmware Over The Air (FOTA) software update for the Telematics Box Module (TBM).

This TSB provides information on updating the TBM software from version 4.37 to 4.38, aiming to improve vehicle data communication and manage ADAS data collection without direct customer symptoms. This update is crucial for maintaining optimal performance of your Jeep Compass Uconnect update system.

Symptoms and Potential Triggers

The primary symptom owners might observe is the message "Uconnect Box requires service. Please visit an authorized dealer." displayed on the radio screen. It's important to note that this message typically appears without any active or stored Diagnostic Trouble Codes (DTCs) being set by the TBM itself.

Beyond this specific message, the software update also includes enhancements to improve vehicle data communication with the server for App data management performance and updates to URLs for ADAS whitelist data collection. These improvements do not typically present as customer-facing symptoms.

Important Warnings and What Owners Should Know

Stellantis TSB 08-039-25 contains several critical points for owners and technicians:

• The "Uconnect Box requires service." message can be triggered by different reasons. For new vehicles recently switched to customer mode, the New Vehicle Preparation procedure should be followed. For vehicles with intermittent concerns, technicians should check the TBM, antenna, and instrument panel harness connections to resolve related DTC issues.
• This bulletin is an Information Only Technical Service Bulletin. It informs dealers how the FOTA update is performed and does not contain a Labor Operation (LOP) for reimbursement. This implies the update is typically handled as part of routine service or automatically.
• Customers will receive a notification on their radio screen when new software is available. Owners have the option to update immediately or schedule it for later. However, there is no option to decline the update indefinitely; the update must be performed.
• For the update to proceed, the vehicle must be in 'Park' and the ignition in the off position.
• If the customer selects "Update Now," they can shut off the vehicle and leave; the update will be completed automatically.
• The update process may take several minutes to complete.

Repair Procedure Summary

The repair involves a Firmware Over The Air (FOTA) update to the Telematics Box Module (TBM) software, upgrading it from version 4.37 to 4.38. This update is delivered wirelessly to the vehicle's built-in cellular modem.

When new software is available, owners will receive a notification on their Uconnect radio screen. They can choose to initiate the update immediately or schedule it for a later time. To begin the update, the vehicle must be parked, and the ignition turned off. Once the owner confirms the update, the process will complete automatically, even if the vehicle is turned off and left. Upon successful completion, a confirmation message will display on the radio screen, indicating that the Uconnect system has been updated with the latest software. This ensures your Jeep Compass Uconnect update is applied correctly.
