  2. By downloading the current firmware version from the car to assist when changing eMMC chip in CID if the eMMC is damaged and can not be read. As a result, with the Tesla Diagnostic Tool, you can extract car configuration from the car without CID and generate files needed for the new CID eMMC image. This way, you do not have to worry about the Spansion chip version.
  3. With the Tesla Scan tool, you can enable GW Serial console to CID.
  4. The Tesla Diagnostic Tool can install the firmware on your car.
  5. Functions for bench setup of IC
  6. Backup and restore IC.

  9. Recode new battery, if different from original
