K-Bus System

The K-bus system utilized in the MINI is the proven K-bus serial communication network used by BMW in the E46. It uses a single wire colored white/red/yellow. The K-Bus used by Body related components to connect with other body electronic systems and the instrument cluster (IKE) is a slow bus system, transmitting at 9600 bits per second.

The K-Bus switches between 0-12 volts (High/Low) and has a low impedance, making it resistant to electromagnetic interference. Most users are active on the bus when the ignition is switched to KLR.

The K-Bus network enters sleep mode 60 seconds after the ignition is switched off. While in sleep mode the K-Bus is at 12 volts.
