Module Programming - BPCM

WARNING: This page is about a different variant/trim than selected.

The Battery Pack Control Module (BPCM) is flash programmable. The flash update should be performed when a software update is available or the PPU is replaced.

  1. The ignition state needs to be transitioned to OFF  for at least 30 seconds prior to flashing the BPCM.
    NOTE:

    This allows the BPCM contactor to be commanded open. If the ignition state is cycled to fast, a precondition warning can happen and this will prevent the flash programming procedure from completing.

  2. Transition the ignition to RUN  .
  3. Start the flash update procedure for the BPCM.
