Last modified: 27/03/2023 16:15:42

Revision History:

CAUTION: DO NOT perform a Partial or CAN reinstall to replace the MCU or DAS/FSD ECU. Doing so might cause irreapairable damage to components.
  • DAS/FSD/IC  : Use Full reinstall (touchscreen or Toolbox) or Garage. FW versions 2022.36 and feature/2022.8.10.6 (Tegra ONLY) onward also have DAS and IC (Tegra only) specific reinstall options
  • MCU  : Use Garage
NOTE: This procedure describes how to reinstall the currently installed firmware using the vehicle touchscreen. The package will not be downloaded from Tesla servers.
  • FW versions 2022.36 and feature/2022.8.10.6 (Tegra ONLY) onward: 
    • Full  : Reinstalls the currently installed firmware package to all components. Useful for when multiple modules are replaced at the same time (for example a DAS ECU and CAN ECU). DO NOT use this for MCU replacements.
    • CAN  : Reinstalls the currently installed firmware package to all CAN ECUs. Do not use this for MCU, instrument panel (IC), DAS, or FSD module replacements.
    • DAS  : Reinstalls the currently installed firmware package to replaced DAS/FSD ECUs.
    • IC (Tegra only)  : Reinstalls the currently installed firmware package to replaced ICs (Tegra only).
  • FW versions before 2022.36 and feature/2022.8.10.6 (Tegra ONLY): 
    • Partial  : Reinstalls the currently installed firmware package to all CAN ECUs. Do not use this for MCU, instrument panel (IC), DAS, or FSD module replacements.
    • Full  : Reinstalls the currently installed firmware package to all components. Useful for when multiple modules are replaced at the same time (for example a DAS ECU and CAN ECU). DO NOT use this for MCU replacements.
NOTE: Firmware reinstall is also available via laptop locally connected with Toolbox. It may save time to reinstall via Toolbox if a laptop is already connected due to the repair procedure. See Firmware Reinstall - Toolbox .
