Active Hydraulic Booster
C1384 Pressure Sensor not Calibrated - General Information

Component Location





General Description

There are three pressure sensors in HPU(Hydraulic Power Unit). They each measure high pressure accumulator pressure, booster pressure, padal simulator pressure. AHB ECU(Electronic Control Unit) uses these measured values to monitor AHB operatoring status and control AHB.
After replacing AHB ECU, pressure sensor calibration is essential.

DTC Description

If no information regarding pressure sensor calibration in the AHB ECU is detected, a failure is recognized.
