Incompatible drive system software detected

What does the GTW_w197_PMRE1RversionMismatch alert mean?

The vehicle gateway (GTW) detects the Pedal Monitor Rear Axle 1 Right Unit (PMRE1R) running a firmware version that may not be compatible with the firmware installed on the rest of the vehicle. May occur after an unsuccessful or incomplete vehicle firmware update, and may be resolved through a successful vehicle firmware update.

What you'll see in your Tesla

  • Incompatible drive system software detected
  • Schedule service - Unable to drive until updated

What triggers it

The GTW detects the PMRE1R running a different firmware version than expected.

When it clears

The GTW no longer detects the PMRE1R running a different firmware version than expected.

Potential impact

Vehicle is unable to drive until the firmware version mismatch is resolved, to make sure PMRE1R functionality is not limited or unavailable due to firmware. Inability to use waste heat to supplement high voltage battery heating may make charging at colder temperatures limited or unavailable.
