IBST_a077_runOutMotorSaturated

Indicates IBST pRunout brake pressure was not reached due to motor torque output saturation.

Live incidence rate

<0.01% (Extremely rare)

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.

Description

Indicates IBST pRunout brake pressure was not reached due to motor torque output saturation.

Cause

Set when IBST cannot reach pRunout with full motor torque output. 300ms debounce time.

Clear condition

Cleared when master cylinder brake pressure from ESP must reach near pRunout value.
