K-bus Interface

This interface transmits data such as the vehicle speed, engine speed and diagnosis between the IHKS control unit and the IKE.

The K-bus is also used to transmit compressor load values as well as auxiliary fan request from the IHKS through the IKE then over the can line to the ECM.
