Overview
These engines are equipped with an electronic control system. The system consists of a computer,
sensors, and software. The system provides these capabilities:
• Control of the engine
• Control of particulate emissions via the “Caterpillar Regeneration System” (CRS)
• Interface with the vehicle
• Fault detection and reporting
Engine Control
The engine’s computer is called the Electronic Control Module (ECM). The ECM monitors inputs
from various sensors and inputs from the vehicle in order to control the engine.
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)
Refer to Troubleshooting, “System Overview” for additional information on the electronic control
system.
“Caterpillar Regeneration System” (CRS)
The CRS contains these components:
Diesel Particulate Filter (DPF) – A DPF is installed in the vehicle’s exhaust system. The DPF
collects soot and ash from the engine’s exhaust.
Aftertreatment Regeneration Device (ARD) – The ARD provides additional heat to the engine’s
exhaust in order to convert the soot in the DPF into gas. The ARD operates only when additional heat
in the exhaust is needed.
Software – Software in the ECM monitors the DPF and the ARD. The software controls the delivery
of fuel, combustion air, and spark to the ARD.
Vehicle Interface
The ECM interfaces with the vehicle via an electrical connector on the ECM. The interface is
configurable. This allows the control system to support a variety of vehicles and applications.
Inputs – The vehicle provides inputs to the electrical connector on the ECM in order to indicate the
status of switches and other controls. The ECM must be correctly configured in order to properly
interpret the inputs. The ECM is configured via the Caterpillar Electronic Technician (ET). Refer to
Troubleshooting, “Programmable Input Parameters” for additional information on configuring the
inputs.
Outputs – The ECM provides outputs for the vehicle via the electrical connector in order to control
lamps, solenoids, and other devices. The ECM must be correctly configured in order for the outputs to
match the vehicle’s configuration. Refer to Troubleshooting, “Programmable Output Parameters” for
additional information on configuring the outputs.
Fault Detection and Reporting
The ECM monitors inputs from the sensors and inputs from the vehicle. Software in the ECM
interprets the inputs. The software determines if the inputs are operating correctly. A Diagnostic
Trouble Code (DTC) is activated when the software detects a problem with an input.
The ECM broadcasts the codes on two data links. The data links are ATA and J1939. Cat ET must
communicate on both data links in order to fully service the engine.
The codes can be displayed on Cat ET and optional displays in the vehicle’s cab. Refer to
Troubleshooting, “Diagnostic Trouble Codes” for additional information on diagnostic trouble codes
and a complete list of codes.
