Diagnostic Trouble Codes (DTCs)
The DGC-500 obtains the diagnostics condition of the transmitting electronic components. The DGC-500
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-500 obtains over the CAN interface.
CAUTION
When the CAN interface is enabled, the DGC-500 will ignore the following sender
inputs: oil pressure, coolant temperature, and magnetic pickup.
