Two versions
An ICM control unit is installed in every F01/F02. Which of the two available versions of the ICM control unit is fitted depends on the vehicle's equipment level.
If the vehicle is equipped with one or both of the following options
- Integral Active Steering (IAL) or
- Active Cruise Control with Stop&Go function (ACC Stop&Go),
the high-performance version of the ICM control unit is installed.
If neither of these options are installed in the vehicle, the basic version of the ICM control unit is used.
The internal layout of the high-end version differs from the internal layout of the basic version in the following ways:
- Larger microprocessor (required to calculate the Integral Active Steering control and active speed control)
- Redundant sensor system for lateral acceleration and yaw rate (safety requirement for Integral Active Steering).
