Version 2.7.0, what is new:

• Added a new key learning method for Model 3/Y that does not require certificates
  You can use the LC005 cable, VVDI, or PeMicro for this method. This new key functionality also allows you to change the VIN in the dump, so the app can bind a key without issues. For VCSEC modules 2021–2024, it’s now possible to flash a blank chip after replacement
• The certificate-based key learning method for Model 3/Y has been improved – certificates are now banned less aggressively
• Added the ability to unlock the network port (Diag Ethernet) on all Model 3/Y vehicles with any firmware via the CAN bus
  This allows you to open all updater ports (Telnet, HTTP, Gadget) and the gateway port for config changes with displays on, without taking apart the MCU
  Tested on M3 Intel HW3.0, MY AMD HW3.1, and MY AMD HW4.0
  For China-market cars, this makes it possible to launch redeploys from LOKI with no restrictions
• Added the ability to install navigation maps on Model 3/Y (Intel/AMD) with the latest firmware without affecting system updates
• Added Service Mode activation via CAN bus for Model 3/Y (especially useful for China-market vehicles)
• Added support for reading/writing secured config for Model S/X (MCU1/2) with the LC005 cable — no extra programmer is needed now
• Added the ability to reset service alerts for Model 3/Y batteries (isolation, VSH, etc)
• Added the ability to reset BMS_w023 on Model S/X batteries
• Improved SDM/RCM operation
• Redesigned the updater page for better usability
• Improved the performance and usability of CAN functions
• Online functions are now more convenient and informative
• Several UI pages have been redesigned to improve clarity

Frequent software updates and the mandatory presence of certificates, even when the vehicle is not in use requires a specialist diagnostic tool. Without such a tool, repairing them is practically impossible. To address this need, we’ve developed Loki the best Toolbox alternative – a specialized diagnostic scanner with no full-fledged counterparts worldwide, serving both car owners and service stations.

Toolbox 3, its features and drawbacks

One of the most common questions directed to Loki diagnostic scanner developers and technical support specialists is the differences between our device and Tesla’s official diagnostic service known as Toolbox 3. Here are the main features and disadvantages of Toolbox:

1. It is Tesla’s official service providing access to the vehicle’s service data, diagnostic trouble codes (DTCs), and other functions. However, its functionality is quite limited, lacking access even to the Factory Mode.

2. Toolbox provides some repair documentation, such as operation manuals for all models and modifications, and electrical diagrams. However, guides for replacing components and assemblies are practically absent.

3. Toolbox 3 is compatible only with vehicles running firmware from 2019 onwards. The number of available commands directly depends on the firmware version, ranging from around fifty in 2019.8 (for Model S/X with Tegra processor) to over 250 in the final version, 2022.8.

3. The previous version, Toolbox 2.1, used on vehicles with Tegra processors, is currently blocked. Along with it, the ports for connection were blocked – for example, beneath the display in the Model S. Now, connecting to this model requires dismantling the instrument panel.

4. Now, arguably the biggest downside of Toolbox 3. Access to its functionality is paid, with a subscription costing about $3000 per year, $500 per month, $175 per day, and $125 per hour. Furthermore, it’s quite finicky, as connection is only possible through Windows via Google Chrome. Tesla provides no technical support, leaving users to navigate issues on their own, which can be quite challenging.

Tesla software structure: Odin and the “Mother Ship”

To understand why this happens, one needs to comprehend the structure of Tesla’s software. Each vehicle runs the Odin service, aiding in various technical maintenance actions. It is within Odin that the firmware and commands we discussed earlier are located. However, despite Odin being based on Python 3, direct connection to the vehicle yields no results – without proper authorization, the car’s computer simply throws an error.

During its operation, Odin must communicate with Tesla’s main service – requesting and receiving permissions for making changes and transferring data. This situation is akin to the concept of certificates – access keys issued by Tesla’s central computer. Without them, communication doesn’t cease entirely but becomes limited. However, without certificates, routine updates of maps and firmware, as well as other full functionalities of the vehicle, become impossible.
Similarly, Toolbox 3 operates. The main center, through Odin, acts as an activator for commands residing on the vehicle itself. Subscriptions exist separately for information on services and Tesla’s software. Essentially, the subscription fee for Toolbox is payment for the company allowing work on the vehicle. Attempting to hack Tesla is practically unrealistic and even dangerous – due to a single mistake, certificates could be annulled.

Advantages of Loki Over Standard Diagnostic Methods

Our LOKI Diagnostic Tool is a great alternative to using Toolbox 3, as it:

● Works with all types of processors and firmware versions.

● Has a more extensive functionality (including Factory Mode).

● Is purchased once, without requiring future subscriptions.

● Comes with qualified online consultations upon purchase.

● Offers the opportunity for training in Tesla diagnostics and repair with our specialists

Most importantly, Toolbox 3’s functionality is already integrated into Loki’s list of solvable issues, eliminating the need for a “this or that” choice when purchasing our device. It’s also worth noting that many features present in Toolbox are available in an expanded range with us. For example:

1. While Toolbox 3 allows diagnostics of the high-voltage battery only in a static variant, Loki enables real-time analysis.

2. Loki allows for cleaning Crash Data when connected via the CAN bus without extracting SRS (RCM, RCM 2) and body controller blocks.

3. With our scanner, features like Key Binding to all existing serial models, changing the car’s configuration, and obtaining live diagnostic data for all systems are available.

In conclusion, our diagnostic scanner possesses functionality that official diagnostics do not and likely will never have, as it’s not in the manufacturer’s factory interests. By acquiring Loki, you gain the most comprehensive control over your Tesla vehicle and the widest range of repair and adjustment possibilities available today.

Version 2.6.0, what’s new:

• Secured Config MS\MX MCU1\2, works only with dumps read through PEMicro
• Added Live Data and DTC removal function for MS THC
• Added key learning for MS\X AMD
• Added reset of Immo and Mothership key for MS (MCU1\2)
• Added ability to edit the odometer upwards for M3\Y (in case it resets to 0)
• Improved MS key learning procedure, no need for jumper on the relay anymore (details in the manual)
• Fixed the operation of the car updater
• Fixed Live Data for BMS M3\Y
• Fixed key learning for M3\Y, mobile app now works properly

For Secured Config MCU1\2 you need to read the dump with a third-party programmer, because our standard cable was not originally designed for MPC5668.
Pemicro Multilink Universal is the best (Multilink FX reads and writes unstably). After reading/writing this chip, you should run validation, because these programmers have been noticed to have glitches in the form of writing/reading garbage.
Keys for MS\X AMD are currently working in test mode, please contact us in case of any problems.

The version has already been sent to all devices, connect it to WiFi and check the update button.

• The manual button now leads to the manual

To update, just connect the LOKI to the internet and press the update button in the settings tab.

Diagnostics and repair of Tesla require the use of Factory Mode. It shows all the information about the car – settings, errors, calibrations, logs, etc.

However, recently garage mechanics specialised in Tesla maintenance have got a nasty surprise: the software version 2021.4.15 released by Tesla has blocked access to Factory Mode via a vehicle. Currently, all the operations are performed via an updater – no scanner can provide access to the car diagnostics.

Almost no scanner…

LOKI has a factory mode, it pulls data from the vehicle CAN bus and displays them through the device interface. LOKI allows specialists to display data of their choosing, including those that were previously inaccessible in Tesla Factory Mode.
