ON-BOARD DIAGNOSTIC OUTLINE [CAN (CONTROLLER AREA NETWORK)]
id094000104000
!
The CAN system related module has an on-board diagnostic function.
!
The on-board diagnostic function consists of the following functions: a malfunction detection function, which
detects overall malfunctions in the CAN-related parts; a memory function, which stores detected DTCs; a
display function, which indicates malfunction locations and status via DTC output; and a PID/data monitoring
function, which reads out specific input/output signals and verifies the input/output condition. Also, the
malfunctioning part can be determined by the combination of output DTCs.
!
Using the Mazda Modular Diagnostic System (M-MDS), DTCs can be read out and deleted, and the PID/data
monitoring function can be activated.
!
A fail-safe function is equipped in case a malfunction occurs in the CAN system. The sending module sends an
error signal and the receiving module illuminates a warning light to ensure safety.
