Cruise Control Program
WARNING: This page does not describe the selected car, but rather 43 other vehicles, including the 2006 BMW M3, 2006 BMW 330Ci, 2006 BMW 325Ci, 2005 BMW M3, and 2005 BMW 330xi. However, it is still accessible from the selected car via links, so may be relevant.
When cruise control is activated, the MS 42.0 control module communicates this status via the CAN bus. The GS 20 activates a program suitable for active cruise control operation preventing pendulum locking/unlocking of the torque converter and minimizes up/down shifting. Additionally, the MS 42.0 can request a downshift if the vehicle speed exceeds the set speed limit when coasting downhill.
