Tesla Introduces New Service Mode Features in 2024.44 Update

Not a Tesla App

Tesla has been continuously improving and adding features to its Service Mode feature, and update 2024.44 is no exception.

Tesla also recently launched Service History for vehicles. With the new additions to Service Mode and price cuts to ToolBox 3 (TB3), their in-house service software, Tesla is really pushing Service accessibility.

Service Mode Improvements in 2024.44

This update introduces several new Service Mode features, so we’ll break down each new feature in Service Mode for 2024.44. Thanks to @max_bracco on X, who shared these photos with us.

Brakes Panel

The Brakes Panel has been updated to allow for the diagnosis of wheel speed sensors, which were previously only accessible in TB3 while physically connected to the vehicle. In addition, information on the Electronic Parking Brake, Electronic Stability Program and iBooster (Electromechanical Brake Booster) are now available in the Brakes Panel as well. 

This new panel is under Chassis > Brakes and has multiple subpanels with brake details. This update is exclusive for the Cybertruck.

Brake Burnishing Update

Brake Burnishing is a process to help condition or break in your brakes, helping to make sure you’ll get optimal performance out of them. It can also be used as regular maintenance for an EV - because you’ll rarely use your friction brakes with Tesla’s one-pedal driving.

The update to Brake Burnishing will now allow you to continue performing this service task even if the vehicle goes into reverse. Previously, any UI, including the rear-view camera, popping up would cancel Brake Burnishing and close the service window - meaning you’d have to restart.

Placing the vehicle back in drive automatically resumes the service task, which makes it easier to do so in a smaller location.

This improvement applies to all vehicles, including legacy Model S and X.

Speakers Panel and Audio Test

A Speakers Panel has become available for some vehicles to help diagnose issues with any of the internal vehicle speakers. You’ll be able to play test tones through any selected speaker or set of speakers. This could be helpful to figure out if a speaker isn’t working properly or to diagnose a rattling speaker or subwoofer.

As part of the Audio Test, you can also play specific frequencies - helping to figure out what exactly is wrong with the speaker. Previously, you’d have to use TB3 to perform this test, so it's nice to see Tesla moving things to Service Mode and increasing accessibility for owners and third-party technicians.

This new speakers panel is only available for the 2024+ Model 3, and the Model Y with the AMD Ryzen infotainment processor.

SCCM Update

The Steering Wheel Control Column (or Yoke) has received updated graphics to correctly display what you’ve got equipped in your vehicle. You’ll also be able to initiate the steering wheel/yoke swap on a Model S or Model X in this UI as required, assuming you’re swapping them.

Previously, this feature was only accessible to Tesla’s Service Technicians or through a fairly complex procedure in TB3 that required outside scripting support - well beyond the knowledge and skills of most third-party technicians who aren’t intimately familiar with TB3. This makes the procedure something that can be done by the user at home - as long as you’re following the Service Manual carefully.

This is only applicable for the Model S and Model X. The Cybertruck has a special Steer-by-Wire panel in Service Mode.

Interior Lighting Diagnostics

Not a Tesla App

The last item to get added to Service Mode is an entirely new panel for testing the ambient lighting system, which is availablle for the new Model 3 and Cybertruck. This panel allows you to diagnose and repair the vehicle’s RGB lighting. It also allows you to view the health state and run an RGB lighting addressing routine, which is required when replacing some of the lighting strips.

Earlier this summer, Tesla also added a Battery Health Test to Service Mode.

Is Tesla Planning to Add Steam Support to All Vehicles?

Not a Tesla App

Yesterday, we reported that Tesla updated their Steam integration on Model S and Model X vehicles. The update was part of their 2024 Holiday Update, but it looks like there may be more to this than a simple update.

Steam, a video game library app, makes it easy for users to buy or launch games on their computers. However, a couple of years ago, Valve, who created Steam, launched their own standalone device, the Steam Deck. The Steam Deck runs a custom OS based on Linux.

Steam Launch

When Tesla launched the redesigned Model S and Model X, Tesla introduced a dedicated gaming GPU with 16GB of RAM and touted the ability to play top-tier PC games in Tesla vehicles.

In 2022, Tesla finally launched the Steam app for the Model S and Model X as part of its 2022 Holiday Update. The Steam app runs Steam OS, the same OS as the Steam Deck in a virtual environment.

However, earlier this year, Tesla stopped including the GPU and Steam (Beta) in their vehicles, and we haven’t seen any updates to the Steam in quite some time. In fact, we thought Tesla was axing their gaming-on-the-go dreams.

SteamOS Update

The Steam app, which is still in Beta, is getting an interesting update for the Model S and Model X vehicles with the discrete GPU.

Those vehicles received an update to SteamOS 3.6 - the same version of SteamOS that runs on the Steam Deck. While nothing has visually changed, there’s a long list of performance optimizations under the hood to get things running smoother.

Comparing Steam Deck to Tesla Vehicles

Let’s take a look at the Steam Deck - according to Valve, its onboard Zen4 CPU and GPU combined push a total of 2 TFlops of data, which is fairly respectable, but much lower than today’s home consoles. The Steam Deck is capable of 720p gaming fairly seamlessly on low-to-medium settings on the go and is also built on the AMD platform.

AMD-equipped Teslas, including the Model 3 and Model Y, are packing an older Zen+ (Zen 1.5) APU (processor with a combined CPU and GPU). AMD claims that the V1000 - the same embedded chip as on AMD Tesla vehicles (YE1807C3T4MFB), brings up to 3.6 TFLops of processing power with it, including 4K encoding and decoding with the integrated GPU on board.

While that’s not enough for 4K gaming or comparable to a full-blown console or desktop GPU, that’s enough raw horsepower for light gaming and is currently more powerful than the Steam Deck.

The Model S and Model X’s GPU brings that up to about 10TFlops of power - comparable to modern consoles like the Xbox Series X at 12 TFlops.

Steam Gaming for All Vehicles?

The fact that Tesla is updating SteamOS even though the feature is no longer available in any new vehicles could indicate that Tesla is not only bringing Steam back to Teslas but that it’s going to play a much bigger role.

While SteamOS is run in a virtual environment on top of Tesla’s own OS, we could see Tesla bring SteamOS to all of its current vehicles, including the Model 3, Model Y, and Cybertruck. Steam in these vehicles would likely support any game that’s capable of running on the Steam Deck.

We think this Steam update, which includes performance improvements and a variety of fixes, has quietly passed under most people’s radars. This could be a very exciting update for those who enjoy gaming, especially for those who love to do it in their Tesla.

Tesla Holiday Update Weather Features: All the Small Details

Robert Rosenfeld / YouTube

As part of Tesla’s 2024 Holiday Update, Tesla included two awesome new features - Weather at Destination and the long-awaited Weather Radar Overlay. These two features are big upgrades built upon the weather feature that was added in update 2024.26. The original weather feature added an hourly forecast, as well as the chance of precipitation, UV index, Air Quality Index, and other data.

However, this update also added some smaller weather touches, such as the vehicle alerting you if the weather at the destination will be drastically different from the current weather.

Not a Tesla App

Weather At Destination

When you’re navigating to a destination and viewing the full navigation direction list, the text under the arrival time will show you the expected weather next to your destination. You can also tap this, and the full weather pop-up will show up, showing your destination's full set of weather information.

Note the weather under the arrival time

You can also tap the weather icon at the top of the interface at any time and tap Destination to switch between the weather at your current location and the weather at your destination.

You’re probably considering that the weather at your destination doesn’t matter when you’re three hours away - but that’s all taken into account by the trip planner. It will add in both charge time and travel time and show you the weather at your destination at your expected arrival time.

And if the weather is drastically different or inclement, such as rain or snow, while you’ve got sunshine and rainbows - the weather will be shown above the destination ETA for a few moments before it tucks itself away.

Tesla also recently introduced a new voice command. Asking, “What’s the weather?” or something similar will now bring up Tesla’s weather popup.

One limitation, though—if you’re planning a long road trip that is more than a day of driving, the weather at destination feature won’t be available until you get closer.

Weather Radar Overlay

As part of the improvements to weather, Tesla has also added a radar overlay for precipitation. You can access the new radar overlay by tapping the map and then tapping the weather icon on the right side of the map. It’ll bring up a radar overlay centered on your vehicle. It’ll animate through the radar data over the last 3 hours so that you can see the direction of the storm, but you can also pause it at any point.

You’re able to scroll around in this view and see the weather anywhere, even if you zoom out. It also works while you’re driving, although it can be a little confusing if you’re trying to pay attention to the navigation system. If you like to have Points of Interest enabled on your map, the weather overlay will hide POIs except for Charging POIs.

Requirements / Data

Unfortunately, you’ll need Premium Connectivity for any of the weather features to work, and being on WiFi or using a hotspot will not be enough to get the data to show up. The data, including the weather radar, is provided by The Weather Channel.

As for supported models, weather and weather at destination are available on all vehicles except for the 2012-2020 Model S and Model X. The weather radar has more strict requirements and requires the newer AMD Ryzen-powered infotainment center available on the 2021+ Model S and Model X and more recent Model 3 and Model Y vehicles.
