Incompatible drive system software detected
What does the GTW_w196_PMRE1LversionMismatch alert mean?
The vehicle gateway (GTW) detects the Pedal Monitor Rear Axle 1 Left Unit (PMRE1L) 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 PMRE1L running a different firmware version than expected.
When it clears
The GTW no longer detects the PMRE1L running a different firmware version than expected.
Potential impact
Vehicle is unable to drive until the firmware version mismatch is resolved, to make sure PMRE1L 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.
