VCLEFT_a207_exitDriveLowLVBusVoltage
Electrical system power reduced
What does the VCLEFT_a207_exitDriveLowLVBusVoltage alert mean?
An issue with the low voltage (LV) electrical system requires the vehicle to come to a stop immediately. The vehicle should enter graceful power-off (GPO) to exit drive, and a separate alert should indicate that condition.
What you'll see in your Tesla
- Electrical system power reduced
- Vehicle shutting down
What triggers it
Lead acid: Low voltage (LV) battery voltage below threshold for 3 seconds (3s); transistor gating LV battery connection is open (no current flow); vehicle load shedding is active; or reverse battery transistor issue detected.
When it clears
Low voltage (LV) battery voltage above threshold; transistor gating LV battery connection is closed; no reverse battery transistor issue detected; vehicle loadshedding is not active.
Potential impact
The vehicle will not enter drive. If the vehicle is driving, it will exit drive through graceful power-off (GPO) to come to a stop immediately. A separate alert should be present to indicate the GPO
