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 verbal 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 SPM/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.
Following messages are displayed with the description:
SPN:100 EngOil Press
SPN:102 Boost Press
SPN:105 Intake Temp
SPN:110 EngCool Temp
SPN:175 EngOil Temp
SPN:629 Controller#1
SPN:636 PositionSensor
SPN:637 TimingSensor
SPN:651 InjectorCyl#1
SPN:652 InjectorCyl#2
SPN:653 InjectorCyl#3
SPN:654 InjectorCyl#4
SPN:655 InjectorCyl#5
SPN:656 InjectorCyl#6
SPN:677 EngStartRelay
SPN:1485 ECU MainRelay
For Scania Fault codes (FC) are displayed. Following messages are available for particular groups of
Fault codes:
FC:1000-1001 Overspeed
FC:1100-1107 EngSpdSensor1
