Kia Carens: ESP(Electronic Stability Program) System / Steering Angle Sensor Description and operation
The Steering Angle Sensor (SAS) is installed in MDPS (Motor Driven Power Steering)
and it sends messages to HECU through CAN communication line.
The SAS is used to determine turning direction and speed of the steering wheel.
The HECU uses the signals from the SAS when performing ESC-related calculations.
Components (Steering Angle Sensor, Torque Sensor, Failsafe relay, etc.) of the
EPS system are located inside the steering column & EPS unit assembly and the
steering column. EPS unit assembly must not be disassemble to be inspected.
They must be replaced. (Refer to “ST (Steering system) Gr.”)
