Body Control Module (BC1): Notes

The BC1, similar in operation to the BMW General Module, controls several systems on the MINI. It is connected to the K-Bus to allow sub-systems to communicate with other systems and to enable diagnostic communication with the sub-systems.

The BC1 is located at the base of the A Pillar on the right hand side of the vehicle. It utilizes four (4) connections: one 20-pin connection and three (3) 54-pin connections.
