Tesla improves Service Mode with alert payload data

Alerts in Tesla's Service Mode will contain additional details on what triggered the alert

@Greentheonly/Twitter

Most modern cars come with access to a Controller Area Network (CAN) that lets you access information about systems in the vehicle.

It's often used to help diagnose vehicle issues and find out if a certain part may need to be replaced.

Teslas, just like other vehicles will display critical alerts or warnings on the screen based on CAN data.

The warnings can be as simple as being low on windshield wiper fluid. They could also alert you of critical issues such as airbag errors or heat pump issues.

Service Mode

For owners or shops who wish to troubleshoot or repair their vehicles, Tesla also includes a Service Mode.

Service Mode gives you access to more details about any alerts the vehicle has shown, as well as letting you reset certain systems.

Not every vehicle alert is customer-facing, meaning that some alerts only show up in Service Mode. These alerts could be temporary warnings without any customer impact, so they're of limited use to the vehicle owner, but they could be useful to a technician diagnosing an issue.

Although Service Mode displays additional details about vehicle alerts, they've also been somewhat limited.

Alerts are triggered based on certain readings from the vehicle's CAN, which provides real-time information on a slew of vehicle systems and any errors they report.

If the vehicle detects a high temperature or low voltage in a given system, it may trigger an alert. The user may see an alert such 'X system not available', although usually the reason is omitted.

In Service Mode, some additional information may be shown about a given alert, such as why it was triggered, such as due to low voltage.

However, up until now the additional information provided in the alert in Service Mode has been somewhat limited.

Alert Payload

In a recent update, Tesla has added individual CAN readings to the alert, known as the alert payload, or crack data. Instead of seeing a simple 'low voltage detected' message, technicians or DIY owners can now see the exact value of the voltage when the alert was triggered.

Twitter user @greentheonly shared this news on Twitter, showing a screenshot that shows the plethora of information that is now available to Model S and X owners. Model 3 and Model Y owners do not yet have access to this data, but it's reportedly coming soon in a future update.

Adding alert payload data to Service Mode is a significant shift, as Tesla kept this information close to the chest and encouraged owners to take their vehicles to Tesla service centers. However, with this kind of information now available, third-party electric vehicle shops will have the data to fix Teslas. Not only shops but do-it-yourself types will also have access to the same information previously available to the technical support team.

That said, it’s important to note that Tesla’s warranty can be voided “due to improper maintenance, service or repairs.” The warranty paperwork, which you should read before ever tinkering with a Tesla, or any expensive item, clearly detailed how the company “strongly recommends that you have all maintenance, service and repairs done at a Tesla Service Center or Tesla authorized repair facility in order to avoid voiding or having coverage excluded under this New Vehicle Limited Warranty.”

@greentheonly’s tweet got a lot of attention. In a follow-up tweet, the user tells readers to enter service mode, and the information can be found in the service mode menu. The tweet is accompanied by a short video showing how to get to service mode. The screenshot shows active alerts with drop-down menus that provide more details.

Reddit comments were supportive of having more information. One poster said: “After they made the service manuals free, I’ve found I can do literally whatever I’d like! I no longer need service to answer questions about parts, processes, or fixes. Just look it up in the manual!”

While another, clearly a DIYer, posted, “This pleases me. Hopefully, between this and the free service manual online, most repairs should be able to be done at home.” 

But another commenter believes Tesla is still holding too much back, “Now give us gateway config tasks on the toolbox, and we'll actually be able to make meaningful changes to our car.”

Keep in mind that Service Mode is aimed at technicians and is not meant to be accessed by customers. The information displayed is not consumer friendly and will often require some vehicle knowledge to be useful.

Service mode will also disable various safety systems while in use, and it is not recommended to be accessed by customers.

Want to See the New Tesla Model Y? Here's Where It’s on Display

Not a Tesla App

Tesla’s refreshed Model Y has started hitting display and Tesla showrooms across North America and Europe, where you can now get up close and personal with the new Model Y and all of its improvements, including the smallest of details.

The refreshed Model Y surprised all of us by sporting its own unique look instead of just being a stretched-out Model 3. While it’s available to order now through the Launch Edition, which includes FSD and Acceleration Boost, deliveries won’t start for another couple of months.

The new front light bar and rear indirect lights make the vehicle unique and worth checking out. There are plenty of new items to check out in the updated interior as well, including new door panels, powered rear seats, and more.

Here’s where you can check out the new Model Y in North America and Europe:

North America

In North America, the updated Model Y can be seen in 19 showrooms across the United States and Canada. The photo below shows the 17 locations in the U.S. and two in Canada. We expect this list to grow as Tesla produces more vehicles and we get closer to the official launch.

New Model Y Displays in North America

Not a Tesla App

Europe

In Europe, the Model Y is already on permanent display at two locations - the Mall of Berlin in Germany, and at Tesla’s Amsterdam Europe Headquarters - both publically accessible. If you’re in the area, definitely drop by and take a look.

Tesla is also holding special events throughout Europe where they’ll be showing the new Model Y through select dates. place to check if you’re far away from the ones above is on Tesla’s Events List.

We recommend checking the page out to confirm any dates, as Tesla will be rotating the locations until each showroom receives its permanent display vehicles.

Tesla will also be visiting major auto shows, including the Toronto and New York International Auto Shows with the new Model Y - so keep an eye out for those events as well.

Tesla's Holiday Update: The 15 Undocumented Features

Not a Tesla App

While Tesla’s exciting holiday update is now behind us, it left us with amazing new features, such as weather radar, Apple Watch support, mobile Dashcam viewer, SiriusXM, and so many other great features that some of us now use every day.

However, it doesn’t end there. Tesla always includes other smaller changes that don’t make it into the release notes, and the holiday update was a big one in terms of undocumented changes.

We’ll go through all the new features that are now available in your vehicle that Tesla didn’t show in their release notes.

Precipitation Map

Not a Tesla App

While this feature did make it to the release notes, some users may still not be aware that the Precipitation Map (weather radar) is now available on all Teslas with the Intel infotainment unit (except for legacy Model S/X). This feature was requested so long ago that, honestly, we didn’t think it’d ever be released. All Model 3, Model Y and 2021+ Model S and X vehicles now have access to the weather radar map overlay.

Fart on Sit

Not a Tesla App

For the Emissions Testing Mode easter egg, you can now have your vehicle fart when someone sits down in their seat.

The sound will come from the direction of their seat. For example, a fart sound will sound from the front-right speaker when someone sits in the front passenger seat. It will play the sound selected in the fart selection box, or play a random fart if you choose "I'm so random."

This option defaults to off after every drive.

Voice Assistant

Not a Tesla App

You can now say 'Hi' or 'Hello' to your vehicle through the voice command prompt, and the vehicle will respond with "Hello!"

This is the first sign of Tesla adding a smart voice assistant to the vehicle, which is expected to be powered by Grok.

Voice Command Changes

Not a Tesla App

If you use Tesla's voice commands, there are a few changes. When you press the voice command button on the steering wheel, you may now not get audible feedback that the button has been pressed. This will depend on whether there’s music playing or other circumstances.

When sending a text message through a voice command, you may now have to press the steering wheel button again to start dictation after choosing a recipient. It’s not clear what’s causing this change, as sometimes it goes straight into dictation mode, while other times it ask you to press the button to start dictation.

Equalizer

Not a Tesla App

You can now reset the equalizer settings with the touch of a button by tapping the new circular arrow to the right of the equalizer. This will bring all settings back down to 0.

Performance Improvements

Not a Tesla App

Intel users are seeing performance improvements while using the Tesla interface, especially in more demanding areas like Tesla Theater. Videos on YouTube now stutter less and Tesla Theater can be minimized more smoothly than before.

The media controls can now control YouTube videos and other web video content as well, even after the vehicle is put into drive.

Service Mode Updates

Not a Tesla App

Several screens in Service Mode have been updated to show larger visualizations, such as the Airbags and Seats menu.

Tesla has also introduced several new visualizations to vehicles with the Intel infotainment unit, that were previously only available on AMD-based vehicles. Some of these includes Coolant and HVAC options.

The only new feature in Service Mode is for the Cybertruck under Service Mode Plus, which includes:

Connector Reference (Service Mode Plus): A new Connector Reference panel is available to help find connectors and highlight harnesses on the vehicle. Rotate the 3D model to explore or type in the search bar to find a specific connector.

Rearranged Menus

Not a Tesla App

With the addition of the Seats menu to settings, Tesla has now rearranged the menu options so that the more used options are now more easily accessible.

The Software menu has been moved up, while other options like Navigation and Trips have been moved down to be close to WiFi, Bluetooth and Upgrades.

Selected Custom Lock Sound

Not a Tesla App

The currently selected custom lock sound is now shown underneath the Lock Confirmation Sound option in the Controls > Locks menu.

Ambient Lighting Easter Eggs

Not a Tesla App

The Rainbow Road and Santa Mode easter eggs have been updated on vehicles that include the ambient lighting feature.

There are new options in these easter eggs that let you enable or disable the ambient lighting while the easter egg is active.

If enabled, the light strips will cycle through colors of the rainbow when the Rainbow Road easter egg is enabled. For Santa Mode, the interior lights will cycle between red, green and white.

Updated Energy App

Not a Tesla App

The Consumption tab in the Energy app has been updated with several changes, including:

• The last 200 miles are now shown, instead of a user-selectable, 5, 15 or 30 miles.

• Instant Range / Average Range has been removed to simplify the interface.

• The average range as moved to the top left and now shows the offset from the vehicle's EPA-rated Wh/mi

• Total energy consumption is now displayed at the bottom left.

• The colors now have different meanings. Before this update, yellow meant the vehicle was using energy, while green meant the vehicle was generating energy through Regenerative Braking. However, now, yellow means that the vehicle consumed more than the EPA average, and green means that the vehicle consumed less than the EPA average and doesn’t necessarily mean it generated energy.

Toll Roads

Not a Tesla App

When navigating to a destination, the alternative routes menu that is displayed when you first enter a destination will now show you which routes include tolls by displaying a dollar sign icon next to the travel time.

Limiting Explicit Content

Not a Tesla App

The Exlicit Content toggle under Audio Settings now applies to YouTube Music as well. This now supports LiveOne, Apple Music, Apple Podcasts, and TIDAL.

Charging Icons

Not a Tesla App

Tesla has redesigned the charging pins that appear on the map. Supercharger and third-party charger pins are now oval-shaped instead of circular.

Instead of just having the number of charging stalls available, Tesla has added the charging icon to make it more obvious these are charging stations.

Adjust Dashcam Viewer Speed

Not a Tesla App

You can now adjust the Dashcam Viewer's playback speed. Users can pick from 0.5x, 1x or 2x playback speeds by tapping the playback speed button.

Tire Pressure Indicator

Not a Tesla App

Tapping the tire pressure indicator will now open the tire pressure card on the left side of the screen instead of opening the Service menu under Controls > Service.

If you ever spot a change that isn’t listed in Tesla’s release notes, we’d love to hear about it!
