BR -96 BRAKE SYSTEM DTC C1235 PRESSURE SENSOR(PRIMARY) - ELECTRICAL COMPONENT LOCATION EE9A1785 EJBF502R GENERAL DESCRIPTION ED1866C3 The pressure sensor, installed in the HECU, sense the brake oil pressure to judge driver’s brake intention when ESP is DTC DESCRIPTION E1F99F60 Each unfiltered input signal voltage is monitored to be in the range of 4.7 V < input signal voltage < 5.3 V. A failure is detected if the output signal value is out of specified range for more than 100 ms or pressure sensor self test form is out DTC DETECTING CONDITION E5CB8634 Item Detecting Condition Possible cause DTC Strategy • Voltage Monitoring Monitoring Period • Continuous Case 1 Enable Conditions • A sensor supply failure is detected if Sensor Supply Voltage > 5.3 V or Sensor Supply Voltage < 4.7 V for t > = 60 ms. Monitoring Period • Continuous Case 2 Enable Conditions • A Fault is set if the DSO signal is voltage of DSO > 4.7 V or voltage of DSO < 0.3V for a time t > = 100 ms. - DSO : original pressure value. • Open or short of pressure sensor circuit • Inoperative pressure sensor |
