DECS-250N CAN Communication
Diagnostic Trouble Codes (DTCs)
The DECS-250N will send an unsolicited message of a currently active diagnostic trouble code (DTC).
Previously active DTCs are available upon request. Active and previously active DTCs can be cleared on
request. Table 18 lists the diagnostic information that the DECS-250N obtains over the CAN Bus
interface.
DTCs are reported in coded diagnostic information that includes the Suspect Parameter Number (SPN),
Failure Mode Identifier (FMI), and Occurrence Count (OC) as listed in Table 3. All parameters have an
SPN and are used to display or identify the items for which diagnostics are being reported. The FMI
defines the type of failure detected in the subsystem identified by an SPN. The reported problem may not
be an electrical failure but a subsystem condition needing to be reported to an operator or technician. The
OC contains the number of times that a fault has gone from active to previously active.
