Uconnect Telematics Box Module (TBM)
What the TBM does
The Telematics Box Module is the cellular modem that gives Uconnect its connected features: automatic crash notification, SOS/roadside assistance calling, remote start/lock via the app, vehicle health reports, and — on newer software — the usage data that can feed Stellantis’s connected-services programs. It works alongside, but is a separate unit from, the Uconnect head unit / radio.
Where it lives
On most modern Ram/Dodge/Jeep/Chrysler vehicles the TBM sits above the upper glovebox, mounted to the dash frame tube behind the passenger-side dash panel. Exact placement shifts by model and year — the PDF has photos and torque-free removal steps per generation instead of a one-size-fits-all description.
The reversible method: don’t pull the TBM fuse directly
A common mistake is looking for “the TBM fuse” and pulling it — on most trims that fuse is shared with the radio and display, so you lose your infotainment screen along with telematics. The cleaner approaches, in order of how non-invasive they are:
- Software disable first. Tools like AlfaOBD can set the TBM’s configuration parameters to disabled through the OBD-II port — no disassembly at all. This is the first thing to try and is fully reversible from the software side.
- Cellular antenna disconnect. Behind the radio, the smaller purple/violet connector feeds the cellular antenna Uconnect uses for its data connection. Unplugging it (radio has to come out first on most models) kills the TBM’s ability to transmit without touching power to the radio or display.
- Upstream fuse (specific position, not “the TBM fuse”). On several platforms there’s a dedicated fuse in the underhood block that feeds just the antenna/modem circuit rather than the shared radio circuit — the PDF lists the correct position per model year, since it is not the same fuse people usually find labeled “TBM” in the door-jamb diagram.
What you lose
- Automatic crash notification / emergency SOS calling
- Remote start, lock/unlock, and vehicle-finder via the Uconnect app
- Over-the-air software/map updates
- Vehicle health reports and Send & Go navigation
What stays working
Bluetooth, USB/CarPlay/Android Auto, the radio, backup camera, and all safety systems (airbags, ABS, stability control) are on separate circuits and modules — none of that runs through the TBM.

Common questions
+How do I disable Uconnect tracking on my Ram or Jeep?
Start with a software disable of the Telematics Box Module (TBM) over the OBD-II port using a tool like AlfaOBD. If that isn't an option, disconnect the TBM's cellular antenna or pull the specific upstream fuse that feeds only the modem circuit.
+Where is the TBM on a Ram 1500?
On most modern Ram, Dodge, Jeep, and Chrysler vehicles the TBM is mounted to the dash frame above the upper glovebox, behind the passenger-side dash panel. Placement shifts by model and year, and on the Wrangler JL it's under the driver's side dash.
+Why did pulling the TBM fuse kill my radio?
On most trims the fuse labeled for the TBM is shared with the radio and display, so pulling it takes out infotainment too. Use the software disable, antenna disconnect, or the dedicated modem fuse instead.
+Does deactivating my Uconnect account stop the tracking?
Calling Uconnect to deactivate the account and SIM stops the subscription and most data upload, but the TBM hardware stays installed and can often be reactivated remotely. A hardware or software disable makes it inert.
