∗ SPN is suspect parameter number.
When the CAN interface is enabled, the DGC-2020 will ignore the following
sender inputs: oil pressure, coolant temperature, and magnetic pickup.
Diagnostic Trouble Codes (DTCs)
The DGC-2020 obtains diagnostic engine information from a compatible engine control unit (ECU). The
DGC-2020 will receive 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 3-3 lists the diagnostic information that the DGC-2020 obtains over the CAN interface.
DTCs are reported in coded diagnostic information that includes the Suspect Parameter Number (SPN),
Failure Mode Identifier (FMI), and Occurrence Count (OC). 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.
