BCMB (Column and Pedal Control Module) Hard Stop/Soft Stop

WARNING: This page is about a different car, the 2018 Lincoln Continental. However, it is still accessible from the selected car via links, so may be relevant.

A hard stop occurs when one of the memory column axes physically reach the end of travel and can go no further. A soft stop occurs when the column stops before it physically reaches the end of travel. The hard stop is set by column design and cannot be changed or adjusted. The soft stop is set by the BCMB (Column and Pedal Control Module). To prevent unnecessary stress on the column and motors, the BCMB (Column and Pedal Control Module) sets soft stop positions, 2 for each moving axis. The BCMB (Column and Pedal Control Module) uses a preset distance from the hard stop to determine where the soft stop occurs. When an axis reaches the hard stop and the switch is held for approximately one second, the BCMB (Column and Pedal Control Module) briefly reverses direction and establishes the soft stop for that axis in that direction. The BCMB (Column and Pedal Control Module) uses this back up strategy to check sensor integrity any time movement has stopped prematurely due to a sensor failure or obstruction.
