External Tester Communication Function
!
The external tester communication function communicates diagnostic information (reading DTCs and reading
input/output signal) by sending and receiving signals between the instrument cluster and an external tester.
Connection and communication information
Serial Communication
!
Serial communication (synchronous communication) is a method of communication in which many pieces of
information are sent and received instantaneously through a single wire.
!
By connecting the Mazda Modular Diagnostic System (M-MDS) to DLC-2, diagnostic information can be sent
and received between the Mazda Modular Diagnostic System (M-MDS) and the instrument cluster via the CAN
communication line.
!
The instrument cluster receives signals for the malfunction detection function and data monitor function from
the Mazda Modular Diagnostic System (M-MDS), and sends information about DTCs and input/output part
operating conditions to the Mazda Modular Diagnostic System (M-MDS).
