Component Location





General Description

The two pressure sensors, installed in the master cylinder, sense the brake oil pressure to judge driver's brake intention when ESC is operating.

DTC Description

The pressure sensor signals are read via A/D converter once per loop.
Each unfiltered input signal value is monitored to be in the range of 5% sensor supply voltage < input signal value < 95% sensor supply voltage.
There is no restriction of the pressure sensor output voltage if the specified operating range is reached or exceeded.
The signal can therefore reach into a fault area without any fault being present in the sensor.
A failure is detected if the output signal stays in one of the fault areas longer than the monitoring time.
