CAN output supports J1939 protocol for basic engine sensor information and
diagnostic troubles codes (DTCs). For J1939 data readers the current implementation
provides engine speed, oil pressure, and coolant temperature. The J1939 is set up
through Terminals 19 and 20, and using the GAConfig Tool.
The EEG7500 responds to J1939 speed requests with the J1939 speed control taking
priority over speeds selected by Speed A and B selections.
J1939 DTC’s are divided into two categories, active and stored. Active codes are
present when a condition is present. Stored codes are a record that the condition
occurred.
EEG7500 can transmit the following DTCs over the CAN Bus.
