What is T-Diag ?

T-Diag - software designed specifically for people who want to be able to diagnose and repair TESLA vehicles. 

The software is constantly updates automatically.

Please note that all functions are supported on non rooted and Tegra based CPU with versions up to 2020.24

* to use white fakra, first you must put car in factory mode via black connector behind IC

These are just some of the features of software:

  • installation new car firmware
  • it can redeploy car (Adjustment of non-original vehicle modules reprogramming of used parts modules)
  •  it have functions to download current firmware version from car to assist when changing EMMC chip in CID if EMMC totally damaged and can not be read. By that way with T-Diag tool you can extract car configuration from car without CID and generate files needed for new CID EMMC image. This way you do not have to worry about Spansion chip version
  • the tool can enable GW Serial console to CID
  • can backup and restore IC
  • can retrofit modules by GW/CID configuration
  • can set configuration if you do US/EU Conversion and swap radio and charger module
  • can recode new battery if different from original

This is FULL Version

Here we sell a Full Version because the competitive T-CAN is cheaper and has most features like in the T-Diag - Main package.
However, the Advanced package has a functionality for only Tesla S, that T-CAN does not have - All Key Lost.
Main Package + Advanced package = Full Version
