Values read from ECU
There is fixed set of values read from J1939 ECU by IL-NT controller:
Î Engine speed (frame EEC1)
Î Engine oil pressure (frame Engine Fluid Level/Pressure)
Î Engine coolant temperature (frame Engine Temperature)
Î Total engine hours (frame Engine Hours, Revolutions)
Î Fuel rate (frame Fuel Economy)
Î Boost pressure (frame Inlet/Exhaust Conditions)
Î Intake manifold 1 temperature (frame Inlet/Exhaust Conditions)
Î Engine oil temperature 1 (frame Engine Temperature 1)
When “ECU LINK”-Modbus option is selected, following values are read from Modbus Register Data (for
QSX15,QSK45, QSK60):
Î Engine Speed (Register Address:30001)
Î Oil Pressure (Register Address:30003)
Î Coolant Temperature (Register Address:30002)
Î Engine Running Time (Register Address:30008-30009)
Î Fuel Consumption Rate (Register Address:30018)
Î Intake Manifold Absolute Pressure (Register Address:30530 (QSK45, QSK60 only))
Î Intake Manifold Temperature (Register Address:30531 (QSK45, QSK60 only))
Hint:
Values read from ECU are not written to history besides the fault codes.
Diagnostic messages read from ECU
Diagnostic messages are read and displayed in extra ECU Alarm list. For Standard J1939 SPN (Suspect
Parameter Number), FMI (Failure Mode Identifier) and OC (Occurrence Counter) are shown together with
text description if available.
One SPN (Suspect Parameter Number) / FMI (Failure Mode Identify) couple describes one fail information. If
FMI is equal to 0 or 1, WRN is displayed in the ECU Alarm list. For any other FMI values, FLS is displayed.
Detail SPN/FMI code specification see in:
x SAE Truck and Bus Control and Communications Network Standards Manual, SAE HS-1939 Publication
x Or refer to corresponding engine manufacturer’s ECU error codes list.
Complete list of text diagnostic messages for each ECU can be found in Comap Electronic Engines Support
manual.
Hint:
IL-NT controller doesn’t support J1587 diagnostic line on Volvo engines. This can cause in some cases a
J1939 alarm message FC:000608 due to missing J1587 bus. Contact your Volvo distributor to update ECU
firmware.
For Scania engines the fault codes are displayed in hexadecimal format.
Analog inputs
Reading of mentioned values from ECU enables to use analog inputs of the unit for other purposes, e.g.
measuring, displaying and alarm activation related to various quantities. The configuration thus allows to use
three analog inputs on the central unit and four analog inputs on IG-IOM/IGS-PTM module if connected.
