∗ SPN is suspect parameter number.
CAUTION
When the CAN bus is enabled, the DGC-2020 will ignore the following sender
inputs: oil pressure, coolant temperature, and magnetic pickup.
Under certain circumstances, the following strings may be displayed on the front panel HMI and in the
Metering Explorer of BESTCOMSPlus
®:
•
NC (Not Connected) - String displayed for a J1939 parameter when the engine ECU is not
connected to the DGC-2020.
•
SF (Sender Fail) - String displayed for a J1939 parameter when the engine ECU sends a special
code indicating a measurement failure for the parameter. For example, if oil sender is determined
to be bad by the ECU, it sends a special code in place of the J1939 oil pressure data indicating a
sender fail condition.
•
NS (Not Sent) - String displayed for a J1939 parameter when the J1939 parameter has not been
sent to the DGC-2020 by the engine ECU.
•
NA (Not Applicable) - String displayed for a J1939 parameter when the engine ECU sends a
special code for the parameter indicating that the parameter is not implemented or not applicable
in the ECU.
•
UF (Unknown Failure) - String displayed when the J1939 parameter data received by the ECU is
not within the valid J1939 data range for the parameter but is not one of the special codes above.
Table 3-3 lists the J1939 data transmitted from the DGC-2020.
