Engine fault codes display

Certain alarms and engine faults generate specific fault codes. These codes are standardised according to the J1939 and/or J1587
standards, except for MTU engines that have a specific transmission protocol (see appendix, if applicable).
Terminology used by the SAE CAN J1939 standard
SPN: Suspect Parameter
Number
FMI: Failure Mode identifier
Terminology used by VOLVO
SID: System Identifier
PID: Parameter Identifier
PPID: Parameter Identifier
FMI: Failure Mode identifier
Terminology used by PERKINS
CID: Component parameter
FMI: Failure Mode identifier
Terminology used by JOHN DEERE
SPN: Suspect Parameter
Number
FMI: Failure Mode identifier
Terminology used by MTU
Displaying faults
This represents the system or component at fault, for example: SPN 100, indicates an oil
pressure problem or a problem with the oil pressure sensor.
This represents the type of fault that has occurred. This may be an electrical, mechanical or
equipment fault.
This term, used in the J1587 standard, has an equivalent in the J1939 standard (SPN).
However, this term corresponds, more particularly, to an assembly of components, for
example, the injection system.
This term, used in the J1587 standard, has an equivalent in the J1939 standard (SPN).
However, this term corresponds, more particularly, to a specific component, for example, a
sensor.
This term, used in the J1587 standard, has an equivalent in the J1939 standard (SPN).
PPID corresponds to PID, but is only used by VOLVO.
This represents the type of fault that has occurred. This may be an electrical, mechanical or
equipment fault. VOLVO uses a SID-FMI or PID-FMI or PPID-FMI combination.
This term used by PERKINS has an equivalent in the J1939 standard (SPN).
This represents the type of fault that has occurred. This may be an electrical, mechanical or
equipment fault.
This represents the system or component at fault, for example: SPN 100, indicates an oil
pressure problem or a problem with the oil pressure sensor.
This represents the type of fault that has occurred. This may be an electrical, mechanical or
equipment fault.
The ADEC and MDEC general system faults are indicated on the equipment in the following
way: fault code numbers (generated by the ECU - Engine control unit).
