NEXON BSVI MCE - SERVICE MANUAL

ELECTRONIC STABILITY CONTROL INTEGRATED PROGRAM (ESCi) 4 D SYSTEM LAYOUT The hydraulic circuit layout of the ESCi system in this TATA vehicle is similar to ABS, i.e., vertical split. For details refer the Hydraulic System Layout in ABS Section. The ESCi system consists of a hydraulic modulator with integrated pressure sensor, electronic control unit and four-wheel speed sensors, which it shares with the ABS system. In addition to the individual wheel valves present for the ABS the ESCi hydraulic modulator has a pair of internal switching valves on the primary and secondary brake circuits from the master cylinder. These are used when brake pressure has to be increased at individual wheels. It has a Integrated yaw rate sensor and steering angle sensor connected via the high speed CAN, which is also used to connect the ESCi to the Instrument cluster, engine and PEPS ECU. There is 1 additional information lamp in the instrument cluster which is used to identify when the system is operating and when a fault has been detected.
