Revision History:

2023-03-23: Added information on the different types of reinstallation vs. FW versions.

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 has 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 replaced components having 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
