By connecting the HDS to the data link connector (DLC), the HDS can retrieve the diagnostic results from the MICU via
a diagnostic line called K-LINE. The K-LINE is distinguished from the CAN line, and connected to the CAN related ECUs.
The MICU is a gateway between the HDS and B-CAN related ECUs, and sends B-CAN diagnostic results to the HDS.
When doing a function test with the HDS, the HDS sends an output signal through the K-LINE to the MICU. The MICU
either relays the request to another ECU, or commands the function its self.
