What you'll see in your Tesla
- Not Available
What triggers it
Set when IBST cannot reach pRunout with full motor torque output. 300ms debounce time.
When it clears
Cleared when master cylinder brake pressure from ESP must reach near pRunout value.
Potential impact
iBooster will have smaller EBR bandwidth but EBR will be executed by ESP thus no change in overall EBR bandwidth. If motor torque is saturated below legal deceleration limit, the PSD (a082) will be set.
