P/S System Description
This electronic power steering (EPS) system consists of a power steering (P/S) control module (3), a torque sensor (4), a P/S motor (5). In this system, the P/S control module determines the level and direction of the assist force for the steering wheel (1) according to the signal from the torque sensor and the vehicle speed signal from BCM (9). The P/S control module runs the motor so as to assist the operation of the steering wheel.
The P/S control module diagnoses troubles which may occur in the area including the following components when the ignition switch is ON and the engine is running. When the P/S control module detects any malfunction, it stops the motor operation.
- Torque sensor
- Engine speed signal circuit
- P/S motor
