C1156 ST ANG SEN COM CIR

Description

INFOID:0000000005258718

The steering angle sensor is connected to the ABS actuator and electric unit (control unit) in addition to CAN

lines. CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle

multiplex communication line with high data communication speed and excellent error detection ability. Many

electronic control units are equipped onto a vehicle, and each control unit shares information and links with

other control units during operation (not independent). In CAN communication, control units are connected

with 2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less

wiring. Each control unit transmits/receives data but selectively reads required data only.

Description

INFOID:0000000005258732

The active brake booster consists of a vacuum booster, an active booster control group and a delta stroke

sensor. If a brake booster system malfunction occurs due to loss of vacuum, the delta stroke sensor will signal

the ABS actuator and electric unit (control unit) that a booster malfunction has occurred. The active booster

then applies supplemental force to the master cylinder relative to the amount of force exerted on the brake

pedal.
