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.
The Ride the Lightning podcast recently featured Tesla’s VP of Engineering, Lars Moravy, covering a wide range of topics—including the upcoming Model S and Model X refresh. However, some of the most intriguing details came from his comments on Tesla’s charging technology.
Moravy revisited Tesla’s once-hyped robotic charger snake, which was showcased years ago before quietly fading from the spotlight. He also dropped an interesting remark about wireless charging but didn’t go into detail.
Death of the Charger Snake
When discussing the Charger Snake, Lars had some strong opinions. It was an internal Tesla project that never gained much traction because engineers ultimately felt it wasn’t necessary.
At Superchargers, most people leave their vehicles to grab food, a drink or simply stretch—making manual plugging the vehicle in a non-issue. There was little justification for a complex, maintenance-heavy robotic charger, especially considering the challenges it would face in winter conditions. Just imagine the nightmare of keeping it operational in snow and ice.
But what about autonomous charging? As Tesla moves toward full autonomy, vehicles will need a way to charge without human intervention. And it isn’t like a Robotaxi passenger is going to like the idea of getting out of their vehicle to plug in either - which would ruin the seamless experience.
Wireless Charging and V4 Superchargers
Not a Tesla App
That’s exactly where Tesla’s wireless charging comes in. We got an early glimpse of its design during the We, Robot autonomy event, where the Cybercab was shown charging wirelessly—without a traditional charging port.
Compared to complex robotic systems for handling charging cables, wireless charging is a far more practical solution. A simple charging mat eliminates the need for moving parts while allowing vehicles to charge without human intervention.
In the future, Supercharger stations will likely support both wired and wireless charging, enabling Cybercab users or owners to charge their vehicles while sleeping, watching video content, or simply relaxing—without ever needing to step outside. Wireless charging may also be cheaper to install than a complete Supercharger stall, which Tesla is now able to install for below $40k per stall.
And here’s the most exciting part. When asked whether wireless charging would require new infrastructure, Lars hinted:
“Could be. But we’re making some smart plays about that with the new V4 Superchargers…”
This suggests that as Tesla expands its V4 Supercharger network, it will include wireless charging capabilities in the upcoming V4 cabinets. While every stall won’t need wireless capabilities, having the ability to add a few wireless chargers per major location will be enough to kickstart Tesla’s Robotaxi network.
The Cybertruck has been named MotorTrend’s 2025 Best Tech Winner for chassis technology—but surprisingly, not for its stainless steel exterior. Instead, the award recognizes its Steer-by-Wire system.
Steer-by-Wire is a technology that many automakers have explored for years, but Tesla was the first to bring it to mass production. Now, tens of thousands of Cybertrucks across North America are driving with this cutting-edge innovation.
As one reviewer put it, “Steer-by-Wire feels as natural as riding a bicycle.”
What is Steer-by-Wire?
Most modern cars use a rack-and-pinion steering system, which creates a mechanical link between the steering wheel and the front wheels. To make steering easier, most vehicles incorporate hydraulic or electric power assist, reducing the effort needed to turn the wheels.
The steering ratio determines how many turns of the steering wheel are needed to move the front wheels from lock to lock. In most cars, this requires 3 to 3.5 full turns, translating to a ratio between 12:1 and 20:1.
Some high-performance sports cars also feature adaptive variable-ratio steering, which adjusts based on speed. At higher speeds, the ratio becomes less aggressive, allowing for added precision and control.
How it Works
The Cybertruck uses a fully electronic Steer-by-Wire system, eliminating any mechanical connection between the steering yoke and the wheels. Instead, the yoke sends inputs to a computer, which then controls independent electric motors dedicated to steering the front and rear wheels.
This redundancy ensures that even if one steering motor fails, the vehicle remains steerable through the other. Tesla also built in a backup power system—one motor runs on 48V low-voltage power, while the truck’s high-voltage battery powers the other.

Steer by Wire replaces traditional mechanical steering with electronic controls, letting you turn the wheels with less effort
The steering inputs are triple-redundant, with two primary sensors monitoring wheel angles and a third acting as a tie-breaker. If the two primary sensors detect conflicting data, the tie-breaker determines the correct reading, and the system alerts the driver to pull over safely if needed. Tesla’s engineering played a key role in the Cybertruck earning a 5-star safety rating.
Beyond safety, the system also features a variable steering ratio. At low speeds, such as in parking lots, the ratio is around 5:1, making tight maneuvers easier. At higher speeds, it adjusts to around 12:1 for greater stability. Unlike traditional steering wheels, the Cybertruck’s yoke maxes out at 340 degrees, removing the need for hand-over-hand turning.
The system is surprisingly intuitive. According to MotorTrend, it only took them three turns to get comfortable with how the Cybertruck steers, describing it as feeling almost natural.
Because of how the steering is designed, there’s rarely a need to remove your hand from the yoke—unless you’re using FSD. Whether navigating a tight parking lot, off-roading, or cruising on the highway, maneuvering a full-size truck has never been this effortless.

With the Cybertruck’s ability to turn its rear wheels, driving it feels almost effortless. Even if you’re not a fan of its design, we highly recommend visiting a Tesla showroom and taking one for a spin—you won’t regret it. The Cybertruck delivers one of the most enjoyable driving experiences, something you’d never expect from its bulky stainless steel exterior.
At low speeds, the rear wheels turn in the opposite direction of the front wheels, greatly reducing the turning radius for tighter maneuvers. At higher speeds, they turn in the same direction as the front wheels, allowing for smooth, stable lane changes without requiring dramatic steering adjustments. This makes highway driving feel remarkably fluid and controlled.

Tesla has already confirmed that future vehicles will adopt features pioneered by the Cybertruck, with Steer-by-Wire being one of them. Since this technology requires a 48V low-voltage architecture, Tesla’s VP of Vehicle Engineering, Lars Moravy, mentioned on the Ride the Lightning podcast that it will be introduced in future models. Moravy also mentioned that the Model S and Model X will be updated later this year, potentially being the first models to take advantage of this.
The main challenge lies in transitioning to a 48V supply chain. Eventually, all Tesla vehicles will operate on 48V, likely incorporating Steer-by-Wire as well. This change should result in simplified parts, easier repairs, and improved handling.
As MotorTrend put it, when Cybertruck engineers replaced the traditional intermediate shaft with a ribbon cable, they didn’t just redefine how to steer a truck—they set the stage for the future of the entire industry.
