Informational PurposesAn informational icon, calling your attention
Note
This procedure describes how to reinstall the currently installed vehicle software using a laptop with Toolbox 3 locally connected. The package will not be downloaded from Tesla servers.
The software reinstall process varies depending on whether the vehicle is equipped with a lead acid or li-ion battery.

Firmware Redeploy (Lead Acid Battery)

  1. Remove the rear underhood apron. See Underhood Apron - Rear (Remove and Replace).
  2. Connect a LV battery maintainer to make sure power is not lost during the software reinstall.

    CAUTION
    If using a 50A or 80A maintainer, make sure the maintainer is set to "Lead Acid" or "Half Power" mode. Failure to do so could damage the LV battery.
  3. Connect a laptop with Toolbox 3 to the vehicle. See Toolbox 3 (Connect and Disconnect).
