2023-2025 Jeep Wrangler and Gladiator Uconnect Box Service Update

Symptoms of the Uconnect Box Service Issue

Owners of certain 2023-2025 Jeep Wrangler (JL) and Jeep Gladiator (JT) vehicles equipped with the Global Telematics Box Module (TBM) may encounter specific warning messages and functional issues related to their Uconnect system. The primary symptom is an error display of "Uconnect Box Requires Service/Wifi Unavailable" pop-ups. This can indicate an internal performance failure within the TBM, affecting the vehicle's connectivity features.

Another related symptom involves pop-ups stating "Uconnect Box Requires Service", which may be accompanied by issues related to the antenna connection. These messages directly impact the functionality of the Uconnect system, potentially affecting services that rely on the telematics module and Wi-Fi connectivity. If you own a 2023-2025 Jeep Wrangler or Gladiator and are seeing these messages, your vehicle is likely affected by this issue, indicating a need for attention to the Global Telematics Box Module.

Associated Fault Codes (DTCs)

When the "Uconnect Box Requires Service" or "Uconnect Box Requires Service/Wifi Unavailable" messages appear, specific Diagnostic Trouble Codes (DTCs) are typically stored in the vehicle's system. These codes help technicians pinpoint the exact nature of the problem within the Global Telematics Box Module (TBM).

• B22A9-96: This DTC is associated with an "Internal Performance Failure" of the TBM. It suggests a malfunction within the module itself, which can lead to the "Uconnect Box Requires Service/Wifi Unavailable" message.
• B1560, B1561, B1562: These DTCs are linked to an "Antenna loose connection" for the TBM. These codes often accompany the "Uconnect Box Requires Service" message, indicating that the system's ability to communicate is compromised due to a physical connection issue with the antenna.

These fault codes confirm that the telematics system is not operating as intended, necessitating a software update to restore proper function and address the underlying cause of the Jeep Wrangler Uconnect Box Service problem.
