2021-2022 Chrysler/Dodge/Jeep TBM FOTA Update TSB 08-125-24

Owners of certain 2021-2022 Chrysler, Dodge, and Jeep vehicles may experience issues with app connectivity. This is addressed by Technical Service Bulletin (TSB) 08-125-24, which outlines a Firmware Over The Air (FOTA) software update for the Global Telematics Box Module (TBM). This update aims to improve the overall app connectivity experience for affected vehicles, including the 2022 Jeep Compass.

Symptoms

The primary symptom addressed by this TSB is a general concern with app connectivity. Owners may notice that their vehicle's integrated applications are not performing optimally or are experiencing intermittent connection issues. This update for the Global Telematics Box Module is designed to resolve these performance concerns and enhance the overall user experience for features reliant on app connectivity.

Cause

The root cause of the app connectivity issues is identified as the existing software within the Telematics Box Module (TBM). The FOTA update will upgrade the TBM software from versions 4.34 or 4.36 to the newer version 4.37, which contains improvements to stabilize and enhance app functionality.

Important Warnings and Owner Information

Owners should be aware of several key points regarding this software update:

• "There is not an option to decline the update indefinitely, the update must be performed." This means that while you can schedule the update for a later time, it is a mandatory update for your vehicle's system.
• "This is an Information Only Service Bulletin to inform the dealer how the FOTA update is performed. This document does not contain a LOP for reimbursement." This indicates that the TSB is for dealer guidance and does not involve a specific labor operation (LOP) for warranty reimbursement, as it's a customer-initiated FOTA update.
• Before starting the update, "The vehicle needs to be in 'Park'. The ignition needs to be in the off position." This ensures the update process can proceed safely and correctly.
• If you choose to proceed with the update, "If the customer selects 'Update Now' they can shut off the vehicle and leave. The update will be completed automatically." This offers convenience, allowing the update to run in the background.
• "This step may take several minutes to complete." Do not be alarmed if the update process is not instantaneous; it requires time to download and install the new software.

Understanding the FOTA Update Process

This TSB, 08-125-24, details the Firmware Over The Air (FOTA) update process for the Global Telematics Box Module (TBM). Vehicles in the U.S. and Canada receive these software updates wirelessly via a built-in cellular modem. The update will upgrade the TBM software from versions 4.34 or 4.36 to version 4.37, specifically targeting improved app connectivity. The national launch for this FOTA update was expected to begin on May 31, 2024, for Chrysler Pacifica (RU) and Dodge Durango (WD) models, and on June 30, 2023, for Jeep Compass (MP) models.

What to Expect During the Update

When new software is available, customers will receive a notification on their radio screen. This notification will display a message such as "Software Update" and inform you that "New software and features are ready for your Uconnect system. Backup Camera, Radio, SOS and several driving assistance features will be unavailable during the update." You will then have the option to select "Update Now" or schedule it for later. Once the update is complete, your radio will display a confirmation message stating, "Your UConnect system has been updated with the latest Software."

Owner Action

If you own a 2021-2022 Chrysler Pacifica, Dodge Durango, or Jeep Compass, you should expect to receive a notification on your vehicle's infotainment screen regarding this FOTA update. While you have the flexibility to schedule the update at your convenience, it is important to remember that the update must be performed as there is no option to decline it indefinitely. Ensure your vehicle is parked and the ignition is off when initiating the update. This update for improved Jeep Compass app connectivity is crucial for optimal system performance.
