Column Integration Module (CIM) (Steering Column Lock Control Module)

The CIM is located behind the steering wheel on the steering column. It contains among other systems the ignition lock, turn indicator switch, low/high beam switch, cruise control switch, info-display switch, wiper switch, receiver antenna for remote controlled central door locking, steering angle sensor, horn switch, start switch for passive entry passive starts (peps), electric steering column lock-ESCL and a small signal speaker. The CIM is connected to two CAN BUS systems: HS CAN and LS CAN. It is also a gateway for data exchange between LS and HS CAN. All components except steering lock are integrated in CIM and do therefore not need additional cables. If the CIM connector is disconnected bus lines between the DLC and the rest of the HS and LS bus systems are interrupted.
