General Information

Important Safety Information
Do not perform any procedures in this
Troubleshooting Guide until you have read the
Operation and Maintenance Manual and you
understand this information. Use only proper tools
and observe all precautions that pertain to the use of
those tools. Failure to follow these procedures can
result in personal injury. The following procedures
should also be observed.
Work safely. Most accidents that involve product
operation, maintenance, and repair are caused by
failure to observe basic safety rules or precautions.
An accident can often be avoided by recognizing
potentially hazardous situations before an accident
occurs.
A person must be alert to potential hazards. This
person should also have the necessary training,
skills, and tools in order to perform these functions
properly.
Safety precautions and warnings are provided in this
publication and on the product. If these hazard
warnings are not heeded, bodily injury or death could
occur to you or to other persons. Perkins cannot
anticipate every possible circumstance that might
involve a potential hazard.
Therefore, the warnings in this publication and the
warnings that are on the product are not all inclusive.
Overview
These engines are equipped with an electronic
control system. The system consists of a computer,
sensors, and software. The system performs these
functions:
• Control of the engine
• Control of particulate emissions via the Clean
Emission Module (CEM)
• Applications control system interface
• Fault detection and reporting
Electronic Control System
The Electronic Control Module (ECM) is a computer
that controls the operation of the engine.
This document has been printed from SPI2. NOT FOR RESALE
The ECM contains a flash file. The flash file is the
software for the ECM. The flash file contains the
operating maps. The operating maps define the
following characteristics of the engine:
• Horsepower
• Torque curves
• Engine speed (rpm)
i06038202
Refer to Troubleshooting, "System Overview" for
additional information on the electronic control
system.
Application Interface
The ECM interfaces with the machine via software
and an electrical connector on the ECM. The software
can be configured.
The application control system provides inputs to the
electrical connector on the ECM in order to indicate
the status of switches. Correctly configure the ECM in
order to interpret the inputs.
The ECM provides outputs for the application control
system via the electrical connector in order to control
lamps, solenoids, and other devices. Correctly
configure the ECM in order for the outputs to match
the configuration of the application control system.
Clean Emissions Module (CEM)
The CEM contains these components:
Diesel Particulate Filter (DPF) – A DPF is installed
in the exhaust system. The DPF collects soot and ash
from the engine exhaust.
Software – Software in the ECM monitors the DPF
and the ARD. The software controls the delivery of
fuel, combustion air, and the spark to the ARD.
Fault Detection and Reporting
The ECM monitors inputs from the sensors and
inputs from the applications control system. Software
in the ECM interprets the inputs. The software
determines if the inputs are operating correctly. A
diagnostic trouble code is activated when the
software detects a problem with an input.
The ECM broadcasts the codes on the J1939 CAN
data link. If a problem is suspected with the data link,
refer to Troubleshooting, "Data Link - Test".
The codes can be displayed on the electronic service
tool and optional operator interfaces. Refer to
Troubleshooting, "Diagnostic Trouble Codes" for
additional information on diagnostic trouble codes
and a complete list of codes.
