Serial communication
!
Serial communication (two-way communication) allows for multiple data to be sent and received instantly along
the same line.
!
By connecting the Mazda Modular Diagnostic System (M-MDS) to the DLC-2, diagnostic data can be sent and
received between the Mazda Modular Diagnostic System (M-MDS) and the DSC HU/CM using the CAN_H and
CAN_L terminals (within the DLC-2).
!
The DSC HU/CM receives the command signals of the malfunction detection function, PID/data monitor
function, and the active command modes function based on the Mazda Modular Diagnostic System (M-MDS),
and sends DTCs and data regarding the operating condition and status of each input/output part to the Mazda
Modular Diagnostic System (M-MDS).
