The JDR100, GAC’s J1939 dual function data reader, is a low-cost universal device that allows users to read standard J1939 engine parameters and Diagnostic Trouble Codes (DTC’s) from engines equipped with J1939 compatible Engine Control Units (ECU). The JDR100 supports six live engine parameters:
- RPM
- Oil Pressure
- Coolant Temperature
- Fuel Level, Battery Voltage
- Engine Run Hours
- J1939 stop
- J1939 warning
- J1939 malfunction
- J1939 protection status messages.
Because the JDR100 is a universal diagnostic code reader, its application is not limited to any particular engine manufacturer or engine size. It is easily installed, which makes it ideal for aftermarket prospects, and, it’s extremely rugged so off-limit applications are never an issue for this device.
J1939 DTC’s are divided into two categories, active and stored (also referred to as previously active). Active codes are present when a condition is present. Stored codes are a record that the condition occurred. Within each DTC, active or stored, there are several distinct data components:
- Suspect Parameter Number (SPN)
- Failure Mode Indicator (FMI)
- Occurrence Count (OC)
- Source Address (SRC)
The SPN is the engine parameter that is out of range (e.g., Oil Pressure, Coolant Temperature). The FMI provides information about the failure (e.g., OUT OF CALIBRATION). The OC indicates the number of times the failure has occurred, and the SRC tells the user the CAN address of the offending device. Note, the JDR100 can record up to 240 DTCs from up to 10 different CAN devices.
If enabled, the JDR100 will display the text translation of the engine parameter or trouble code information.
