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, Fail-Safe 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 COMPONENTS )
