Tesla continues to improve its Service Mode, which makes it easier to diagnose issues and replace parts. In Tesla update 2023.38, Tesla added a new brakes service panel that allows diagnosing wheel speed sensors and various brakes systems.

New Brakes Panel

There’s a new brakes panel in Service Mode that allows owners and service technicians to diagnose wheel speed sensors, the Electronic Park Brake (EPB), Electronic Stability Program (ESP), and Electromechanical Brake Booster (iBoostor). You can also perform certain actions, such as releasing EPBs, bleeding brakes, and running a stiffness test, according to the Service Mode release notes.

Tesla continues to expand the abilities of its Service Mode, which facilitates the maintenance of the vehicle for Tesla service centers and traditional repair shops. Elon Musk has stated that Tesla is striving to significantly improve the efficiency of its service centers in an effort to reduce wait times, and this likely helps accomplish that.

In update 2023.32, Tesla also made Service Mode changes by improving service alerts and added a new ECU status panel as well as updates to the low voltage battery and heat pump panels.

Before that Tesla added the ability to diagnose issues with the steering wheel stalks and scroll wheels in update 2023.26.

Access to Service Mode

Service Mode is a “hidden” app in every vehicle that lets owners with more advanced knowledge perform certain actions to diagnose or service their vehicles. Although the app is meant for Tesla service centers, anyone can access Service Mode. Keep in mind that certain vehicle safety features are disabled when Service Mode is enabled and the vehicle should not be driven in most cases.

Other Changes in 2023.38 Update

Other Service Mode changes in update 2023.38 include changes to the Camera Preview, which is allows you to change the pitch of the camera, as well as enhancements to “Instruction HV Shunt Replacement (Service Mode Plus)” and “Airbags, and Seats Panels.”

Camera Preview

Preview the front camera pitch verification lines and other cameras as well.

To do so, tap Driver Assist > Cameras.

Enhanced instruction HV Shunt Replacement (Service Mode Plus)

New instructions with an image to help you find the shunt resistance value and run the shunt replacement routine.

To do so, tap High Voltage > Tools > Shunt Replacement.

Enhanced Airbags and Seats Panels

Tesla FSD V12.5 to Enable Sunglasses-Friendly, Nag-Free FSD

By Karan Singh

Tesla has made some significant improvements with FSD 12.4, primarily, the removal of the steering wheel nag under certain conditions. However, there’s a caveat – you can’t wear sunglasses.

According to Elon Musk, FSD v12.5 will introduce support for nag-free FSD, even if you’re wearing sunglasses.

FSD V12.5 is an Upgrade

Ashok Elluswamy, Director of Autopilot Software, also took to X recently to mention that v12.5 is a big improvement to FSD v12.4. While he didn’t mention any specific details, this lines up with some of Musk’s previous comments that each FSD v12 iteration will see major improvements to the FSD model.

Elon also mentioned that while Tesla has a massive fleet of cars, their laser focus on making FSD work, rather than touting every daily achievement – has been their key to making generalized self-driving cars work.

FSD v12 has been pretty much a complete rewrite of the FSD city streets software stack, with drastic improvements over FSD v11. However, certain parts of the software stack haven’t been updated yet. Some features, like the updated highway stack are expected to be in FSD v12.5, which Musk confirmed recently. However, other features such as Park Seek and Banish Autopark, which were expected to arrive with FSD V12.4 are still up in the air.

What about V12.4?

FSD V12.4.3 is currently out to about 5% of the fleet (about 20-25% of FSD users) and hasn’t been pushed out again since about July 10th. Our new auto updating statistics pages can help break this down for folks who are curious.

Installed on 5.4% of fleet

Last updated: Jul 22, 5:45 pm UTC

Given that it’s been some time since any new vehicles have received V12.4.3, it seems the rollout has been stopped. There could be any number of reasons for this – including software bugs, or a lack of confidence with FSD. Additionally, it could just halted in favor of focusing resources on V12.5.

While we’d love to see more vehicles get v12.4.3, we’re likely to see v12.4.4 or v12.5 being the next big waves of deployments to customers. Either way, early-access testers and Tesla ADAS testers will receive these updates first, and then they’ll roll out to the vast majority of customers once Tesla feels confident there aren’t any major issues. Tesla does all this testing in the name of safety, and it's essential that bug-free versions of FSD are the versions that are rolled out wide.

So, for now, leave your sunglasses on and hang tight for the next FSD update.

Tesla Aims To Launch Cybertruck in Canada After Transport Canada Makes Exception for Steer-by-Wire

By Karan Singh

Tesla has confirmed that they’re aiming to launch the Cybertruck in Canada later this year. Transport Canada recently granted Tesla and the Cybertruck a unique exemption to allow steer-by-wire functionality (h/t Sawyer Merritt).

Steer-By-Wire Exemption

We previously reported that the Cybertruck was facing delays due to a steer-by-wire regulatory issue with Transport Canada. On Friday, July 19th, Transport Canada issued a message stating that they would exempt the Cybertruck, for all its models, from part of Canada’s Motor Vehicle Safety Act, which currently doesn’t permit the usage of steer-by-wire systems.

The period that the exemption begins seems to be immediate – July 19th, 2024, and will last through July 18th, 2029, whereafter regulation should supersede the exemption. In the meantime, Tesla will provide a semi-annual incident report, beginning on January 18th, 2025, including information on steering system malfunctions or failures, as well as corrective measures and customer complaints.

It seems that Transport Canada will also have to be notified every time Cybertruck’s steering software is provided with an OTA update, which could result in some update delays in Canada.

Canadian Cybertruck Soon?

With all this information, it sounds like Tesla is aiming to launch the Cybertruck to Canadian customers sometime relatively soon, as they stated they’re still aiming by the end of the year. There is a good chance that they may begin converting pre-orders to orders once Tesla. Tesla hasn’t commented on which model will be available in Canada, but it wouldn’t surprise us if it’s limited to the Foundation series in Canada in the initial release.

We could expect the first customer Cybertrucks (Roshel Defence and a few private importers notwithstanding), to be on Canadian roads in just a couple of months.
