Tesla recently released software update 2025.2 with several new features, including Hands-Free Frunk and Trunk support for Android, a chime for rear cross-traffic alerts, and third-party charging preconditioning.
However, there are also several new features added to Tesla’s Service Mode and Service Mode+.
Recently, Tesla also added other improvements to Service Mode, including an Interactive Wiring Diagram for the Cybertruck, as well as a new speakers panel and audio test, ambient lighting features and more.
Service Mode Updates
Service Mode allows anyone to access service-related features that help troubleshoot vehicle issues. It’s available for free to all Tesla owners, but caution should be exercised when making any changes. More information about how to access Service Mode is available in our Service Mode guide.
In update 2025.2, Tesla improved two existing Service Mode panels:
Brake Burnishing - Brake burnishing helps condition new brakes and rotors. Tesla states: “The Brake Burnish procedure parameters have been updated to reduce the need for coming to almost a complete stop during each cycle.
This change is available for all vehicles.
Charge Port Calibration - Users can now run a charge port calibration, which can help to either get the charge port to fully close or fully open if you’re having issues or if you’ve refitted or retrofitted the charge port on your own. This was previously a command-line tool in ToolBox3.
In the release notes for service mode, Tesla states: “The charge port door calibration routine (PROC_CP_X_DOOR-SENSOR-CALIBRATION) and charge port latch calibration route (PROC_CP_X_LATCH-CALIBRATION) have been added to the Charging panel. Those routines are required to be run following the replacement of the charge port or charge port door.”
This change only affects the legacy Model S and Model X.
Service Mode+ Updates
The rest of the improvements to Service Mode are exclusive to Service Mode+, which requires a subscription to Tesla’s ToolBox3 software and a connection to a computer. Tesla has added new panels and several improvements to Service Mode+ with update 2025.2.
Accessories Panel - “A new Accessories panel is available to view and change configurations for accessories during retrofits, such as tow package, power liftgate, and soiler. To access the new panel, tap Low Voltage > Accessories.”
Previously, technicians had to manually enter all these configuration changes using the terminal.
This is for all Model 3s and Model Ys.
Signal Viewer Panel - “A new Signal Viewer panel is available to monitor multiple signal values live on a graph. If one or more of the signal values is unavailable, the graph will stop updating. To access the new panel, tap Tools > Signal Viewer.”
This will help technicians diagnose issues in real time when they’re related to signal quality or signal noise throughout the vehicle’s internal electrical systems.
This new panel is available on all vehicles with the AMD Ryzen infotainment processor.
Noise Recording Panel - “To improve the user experience, the recording duration has been decreased to 30 seconds, and reliability of the download routine PROC_ICE_X_FETCH-DIAGNOSTIC-AUDIO-RECORDS has been improved.”
The Noise Recording Panel, which was introduced with the 2024 Holiday Update, has been better tuned to improve technician experience while debugging noises or audio issues within the vehicle.
This particular improvement is only for the Cybertruck.
There’s rarely a software update that goes out that doesn’t include improved or new Service Mode panels. While this update focuses more on improvements to Service Mode+, it still includes other improvements to Service Mode. While these updates are aimed at Tesla technicians and third-party technicians, they also help consumers’ right to repair.
Tesla recently also started selling some vehicle parts directly to consumers through their service catalog.
