Steering Column Lock Module (SCL) (4/102) [2018-2022]: Description
The Steering Column Lock Module (SCL) locks and unlocks the steering column, which protects the vehicle from unauthorized usage. The SCL receives commands from the Central Electronic Module (CEM).
The Steering Column Lock Module (SCL) consists of the following:
- An electric motor
- A spring bolt
- A control module
The Steering Column Lock Module (SCL) locks the steering column lock using the spring bolt and the electric motor which activates the movement of the spring bolt. The control module transmits information about the position of the spring bolt to the Central Electronic Module (CEM) upon request.
The electric motor is not able to unlock the column lock if the steering wheel is loaded and there is too much pressure on the spring bolt. A slight movement of the steering wheel reduces the pressure on the spring bolt, allowing the motor to unlock the column lock.
