C1156 ST ANG SEN COM CIR
DescriptionINFOID:0000000001731152
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.

DescriptionINFOID:0000000001731171
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.
