When “ECU LINK”-Modbus option is selected, following values are read from Modbus Register Data
(for QSX15,QSK45, QSK60):
Engine Speed (Register Address:30001)
Oil Pressure (Register Address:30003)
Coolant Temperature (Register Address:30002)
Engine Running Time (Register Address:30008-30009)
Fuel Consumption Rate (Register Address:30018)
Intake Manifold Absolute Pressure (Register Address:30530 (QSK45, QSK60 only))
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:
SAE Truck and Bus Control and Communications Network Standards Manual, SAE HS-1939
Publication
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:
InteliLite 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.
