Tesla Service Mode: How to Access It and What It Does

Tesla's Service Mode

Not a Tesla App

Tesla ships a very detailed and comprehensive diagnostic and repair utility that is available in-vehicle, without requiring external plugs, adapters, or computers. It helps both Tesla and 3^rd party technicians service Tesla vehicles far more efficiently.

Who Can Access It?

Unlike many other vehicle manufacturers, who require OBD-2 ports, service subscriptions, and other external utilities, anyone can access Tesla’s service mode. All owners and 3^rd party technicians can access Service Mode by simply entering a special mode in the vehicle.

What Features Does It Have?

Service Mode is a special hidden app in the vehicle that provides various diagnostics tools that let you test various vehicle subsystems and components. Remember that if you’re exploring service mode on your own, you’ll want to be careful. Many of the features kept inside Service Mode are intended for debugging or repair – and not for the average user, however, Tesla provides a very user-friendly interface.

The options available will vary based on the vehicle and the systems available in that vehicle. For example, the Model S will have a diagnostic tool to troubleshoot its door handles, while the Model X will have one for its falcon-wing doors, but most tools will apply to a wide range of vehicles.

How to Access Service Mode

Tesla’s Service Mode is accessible via the touchscreen with just a few taps. Go to the vehicle controls button (the car icon), and tap the Software tab. After that, locate the vehicle model badge, (e.g. MODEL Y Long Range), directly beneath the vehicle image.

Tap and hold the word “MODEL” for 2 seconds, until you see a small ripple then let go. A menu and on-screen keyboard will pop up, prompting for an access code. Type the access code “service”.

Once you do this, it will bring up the SERVICE menu and a new app in the dock that’s red with a wrench. The entire display will also have a red border around it, indicating the vehicle is in Service Mode. Do NOT drive the vehicle in Service Mode, as many safety features are disabled while Service Mode is active.

How to Exit Service Mode

Once again, you can disable Service Mode from the primary display. If you’ve gone into another app, locate a bright red icon with a wrench in the dock or in the All Apps menu.

Once you bring up the Service Mode app, tap on the last icon in the left column. It’s red and shows a door with an arrow. Simply tap and hold this icon for several seconds to exit Service Mode. You’ll know once Service Mode is exited because the red border around the screen will be removed.

If you can’t find the Service Mode app, start Service Mode again by going to Controls > Software and holding the badge icon to enter Service Mode mode again. Once you’re back in the menu, tap and hold on the red exit icon.

Vehicle Info

Tesla breaks Service Mode into various sections which we’ll go through below. The Vehicle Info section provides most of the same information available in the vehicle’s Software menu, showing you things such as VIN, Autopilot computer, software version and more. At the bottom, you also have access to Service Alerts, Service Settings, Software Reinstall, and a Touch Screen check to confirm your display is working correctly. There is also a button for Additional Resources, which takes you to your vehicle’s Service Guide online.

Driver Assist

This tab has two menus – Cameras and ECU. The Cameras menu provides nominal information on the vehicle cameras, including pitch information – useful for technicians working on the windshield. You can also clear camera calibration from here – but you can also do that within the regular vehicle menus and get a full preview of all cameras.

The ECU tab provides information on the vehicle's electronic control unit and GPS/GNSS.

Infotainment

Not a Tesla App

The Infotainment tab has two menus – Connectivity and Software. The Connectivity menu provides information on Wi-Fi and Cell connectivity and the status of the vehicle’s modems. You can run tests on either modem from here.

The Software tab provides information on the vehicle’s downloaded software and backup banks. Here, you’ll see that both the infotainment and Autopilot systems have 2 side-by-side banks – one keeps the previous update. Map info is also available here. These will be blank or display “—” while updating.

High Voltage

High Voltage section of Service Mode

Not a Tesla App

The High Voltage section is one of the most useful menus – it provides you with the ability to conduct Battery Health tests. The UI here provides information on the entire high-voltage system, including the battery, inverter, motors, vehicle charger, as well as the contactor and high-voltage pyro fuse.

The second tab in the high voltage menu displays the temperature of the battery and details on connected charging apparatuses.

Low Voltage

The Low Voltage system is all the other electronics in the car, and it provides information on the various low voltage components, including the 16v Lithium-Ion (or 12v Lead-Acid, for older vehicles).

This UI is drastically different in the Cybertruck – where it does not run on 16v, but rather 48v.

The last piece of the Low Voltage UI is Homelink. If you purchase Homelink – an add-on module – Tesla will install it for you. If you choose to install it yourself, you can commission the Homelink module through this menu. In the menu, you can also see how many devices are programmed and how many codes have been transmitted with HomeLink.

Thermal

The Thermal menu displays the status of the HVAC system, as well as the battery’s portion of the loop. It’s one of the coolest-looking menus since its animated.

It provides options for self-tests, as well as several options for the coolant and thermal pumps. This UI is for vehicles with heat pumps – legacy vehicles will have an A/C compressor and resistive heating.

This is also where you can view the status of your cabin and HEPA filters, and you can see if they need to be replaced.

Chassis

The Chassis menu provides you with steering options – and the ability to view or adjust your steering wheel offsets, look at suspension information on the Model S and X, re-calibrate the steering column, and confirm each of the buttons on the steering wheel and its stalks are working as expected.

It also provides you with some details on the vehicle’s brakes – showing some test and brake bleed options. An option for Brake Burnishing option is also available here.

Closures

The closures menu shows the status of windows, or automatic doors as well as the status of the front and rear defrosters. You can recalibrate each window and confirm it’s working properly. On the Model S it displays information on the automatic door handles, on the Model X it has a test for the gull-wing doors and for the Cybertruck you can test the tonneau cover.

Safety & Restraints

Safety & Restraints section of Service Mode

Not a Tesla App

This menu simply displays the status of airbags, seat restraints, occupancy sensors and the pyro fuses in them, letting you confirm that each item is working properly and doesn’t have any faults.

Service Mode+ and Toolbox3

Of course, Tesla does have their own way of getting even more data than what is provided in Service Mode, through Service Mode+ and Toolbox3 – a subscription-access service similar to other vehicle vendors.

Service Mode+ is an additional set of tools that are internal to Tesla and require a Toolbox3 setup and subscription to access. It provides further information to fleet owners, collision centers, and Tesla technicians to diagnose and repair vehicles, as well as providing the capability to easily enable or disable Service Mode on vehicles remotely.

Toolbox3 is a subscription service that Tesla offers 3^rd-party technicians and collision centers for around $3,000 per year or a hefty $500 for 30 days. Toolbox3 is installed on a computer and uses a special vehicle interface cable connected to the vehicle. If you’re a technician looking for details on how to set up or use Toolbox3, Tesla’s Online Service Manuals provide a per-vehicle and per-hardware spec guide on how to set it up.

Tesla FSD in Europe: June Update

Not a Tesla App

The road to bringing FSD to Europe has been a long and complex one and filled with regulatory and bureaucratic hurdles. Elon Musk, as well as other members of Tesla’s AI team, have previously voiced their grievances with the regulatory approval process on X.

However, it appears that there is finally some progress in getting things moving with recent changes to upcoming autonomy regulations, but the process still seems slow.

Waiting on the Dutch

Elon commented on X recently, stating that Tesla is waiting for approval from Dutch authorities and then the EU to start rolling out FSD in Europe. Tesla is focusing on acquiring approvals from the Dutch transportation authority, which will provide them with the platform they need to gain broader acceptance in Europe. Outside of the Netherlands, Tesla is also conducting testing in Norway, which provides a couple of avenues for them to obtain national-level approval.

The frustration has been ongoing, with multiple committee meetings bringing up autonomy regulation but always pulling back at the last second before approving anything. The last meeting on Regulation 157, which governs Automated Lane Keeping Systems, concluded with authorities from the UK and Spain requesting additional time to analyze the data before reaching a conclusion.

Tesla, as well as Elon, have motioned several times for owners to reach out to their elected representatives to move the process forward, as it seems that Tesla’s own efforts are being stymied. 

This can seem odd, especially since Tesla has previously demoed FSD working exceptionally smoothly on European roads - and just did it again in Rome when they shared the video below on X.

DCAS Phase 3

While the approval process has been slow, Kees Roelandschap pointed out that there may be a different regulatory step that could allow FSD to gain a foothold in Europe.

According to Kees, the European Commission is now taking a new approach to approving ADAS systems under the new DCAS Phase 3 regulations. The Commission is now seeking data from systems currently operational in the United States that can perform System-Initiated Maneuvers and don’t require hands-on intervention for every request.

This is key because those are two of the core functionalities that make FSD so usable, and it also means that there may not be a need to wait years for proper regulations to be written from scratch. Now, the Commission will be looking at real-world data based on existing, deployed technology, which could speed up the process immensely.

What This Means

This new, data-driven regulatory approach could be the path for Tesla to reach its previous target of September for European FSD. While the cogs of bureaucracy are ever slow, sometimes all it takes is a little data to have them turn a bit faster in this case.

Alongside specific countries granting approval for limited field testing with employees, there is some light at the end of the tunnel for FSD in Europe, and hopes are that a release will occur by the end of 2025. With Europe now looking to North America for how FSD is performing, Tesla’s Robotaxi results could also play a role.

Tesla Launches 'TeslaVision' Contest With Big Prizes — See Last Year’s Winner [VIDEO]

Not a Tesla App

Tesla’s marketing has always been relatively unconventional, relying on word-of-mouth rather than traditional advertising. The passion of the owner’s community is always massive, but it is especially high now with the launch of the Robotaxi network just around the corner.

Tesla is now tapping into that spring of fan creativity and announced the TeslaVision video contest, with some seriously impressive prizes up for grabs.

Announcing the TeslaVision fan video showcase

Tesla owners & supporters have always been able to see our products & mission for what they truly are.

Your word of mouth has made Tesla what it is today.

The OGs will remember that in 2017, we held our first video contest. 8 years… pic.twitter.com/6pPpkqmqOH

The Contest

The core of the contest is simple. Create a video that shows how your Tesla gives you more in life. Tesla is looking for submissions that highlight themes of freedom, safety, fun, and convenience.

Prizes

The prizes definitely make this contest worth entering if you’re good with a camera and have some basic video editing abilities.

For North America, the prizes include a brand new Model Y AWD Long Range, alongside an all-expenses-paid trip to Austin for a tour of Giga Texas. The grand prize winner will also be able to custom order their Model Y, allowing them to select their preferred wheels and color.

The two runners-up won’t get a Model Y, but they’ll also enjoy an all-expenses-paid trip to Giga Texas for a tour of the factory.

The travel and tour include lodging in Austin for 2 nights, as well as economy-class round-trip tickets from anywhere in North America. Tesla will also provide a vehicle for use during the trip.

Hopefully, these winners will also have the opportunity to experience the Robotaxi network while they’re in Austin, as it’s expected to be opened to the public later this month.

Project Loveday

For long-time followers of Tesla, this contest may feel familiar. The contest is a direct throwback to the 2017 Project Loveday contest, which was inspired by a letter to Tesla from a 10-year-old aspiring marketer. That contest was won by MKBHD, with his submission below:
