To determine the torque, a magnetic sensor is used, which converts the magnetic signal into a current signal, according to the relative angular change between the input and output of the torsion bar.
The EPSCM is located on the steering column in the vehicle interior.
Security measures
1. The electronic elements of the system that have been impacted must be replaced with new ones.
2. Exclude the location of the electronic elements of the system from exposure to high temperature and humidity.
3. Do not touch the connector pins as they may be deformed and expose the system to static electricity.
4. Disconnect and connect a socket at the switched off ignition.
