STool is designed to correct the odometer readings on a vehicle.
Programming method: via diagnostic connectors/pads/heels. To operate the program, (depending on the licenses used), adapters are required: Denso adapter and cable ELS27.
The program's capabilities are constantly being updated! Program updates include both free and paid options, depending on the type of licenses purchased.
Minimum possible order: STool USB key with a basic license + 5 paid non-FD licenses of your choice.
The technical support is provided by the developer.

the Central Gateway blocks the panel on the car.
The patch for panels with mb91F037+93c66 has been reworked, now Kia Cerato is made with all firmware versions, the patch itself turned out to be quite intricate and therefore should work not only on the declared models.

The EOL Configuration function (Variant Coding) is used to activate and deactivate various options in the instrument cluster*:
Note:
The functions work on panels developed after 2013, for example on Kia Rio with red displays the function does not work, if the panel supports coding then not all functions can be turned on and off, for example on Airbag, although there is a check mark, it is usually on all the time.
Denso adapter.is required.

*Requires panel disassembly. Works in-circuit by points near the processor. Not through the rear panel connector!
!!! The bootloaders have been fixed, the mileage should no longer «freeze» after adjustment (needs to be checked).
Features:
1. When working with ST012, a detailed log file is created, so after reading or writing the mileage or eeprom, the form is blocked for a few seconds (while the recording is in progress), no need to be afraid of this, that’s how it’s intended.
2. The Trip button on the connection is only needed if you want to turn on the panel after adjustment and check the result, and the dashboard displays the daily mileage instead of the mileage, to do this, press Trip and watch ODO, the button is not needed for the adjustment itself.

CAN FD adapter for STool
New FD adapter from STool. Due to the transition of manufacturers to the new CAN FD bus, and it was also decided to use the new adapter to enhance software protection, with the key algorithms transferred to the adapter.
Adapter for working with the STool software. The adapter works via MBUS and Denso.

FD101 (Gateway Certification)
Verified with licenses FD102, FD103, FD104.
After sending a certificate to the Gateway, it does not block the exchange and the panel can do not remove from the car for mileage correction, recording its prom and other actions.
Operating procedure:
Gateway Certification -> Start making a panel
Gateway Certification -> Stop
License FD101 (Gateway Certification)
Note: You need to have a CAN FD adapter and a Denso adapter.
Hyundai, Kia DNKR panels on the R7F7014xx processor with preparation.
First, 0 km is set via the Denso adapter, then the desired mileage is set via the CAN FD adapter.
License FD103
This is a paid add-on to ST002 (requires CAN FD adapter)
How to work with FD103 license
Select the port to which the CAN FD adapter is connected and click «Test», if the adapter is working correctly, the serial number of the adapter and the activation status will be displayed in the «Information» window.
The program supports two ways of working with the panel:
1. With preliminary reading of Flash, to search for unlock codes in it.
2. With panel unlocking using already known codes.

ELS27 v5 Adapter
ELS27 v5 is a new car diagnostic adapter that combines full compatibility with ELM327, high reliability and speed of work with on-board networks of the car. The device supports work with CAN-bus and K-L-lines of cars. Can be used for diagnostics of various car systems, reading/resetting fault codes (DTC), enabling/disabling additional functions, modules and much more. Due to high quality of workmanship and stable operation, as well as low cost, the adapter has received wide recognition among repair specialists and owners of Ford and Mazda cars.
ELS27 adapter updates:
The protocol scheme has been revised and the connection (jumper) Pin 8 - Pin 9, as well as Pin 7 - Pin 12, has been removed. The mechanical relay has also been replaced with a separate transceiver and another one has been added for the CAN line on pins 12/13 (often used in Renault).

Flash and EEPROM Programming Signal (FEPS) is a signal for switching ECU units to programming mode. It is used for Ford units manufactured before 2011.
R - reset, resetting the module settings. M - mode, WiFi or Bluetooth mode (depending on the mode, the corresponding LED (B or W) next to the button lights up. Attention! This lot does not have a built-in wireless module!
The board with the processor and the interface board are two different boards, which means we can "update" earlier versions of adapters starting with v3.0 to v5.0.
