LCD Add-on for the Arduino DUE (Original Build)

Adding a LCD module to your DEF Simulator is a fun extra project for the slightly more techie people.  The current Simulator code already has support for the LCD module included.  The module can display the initialization status, simulated tank level and simulated DEF temperature. The LCD module uses different digital I/O pins on the Arduino DUE vs the UNO/ATMega2560. The module can be built on simple perforated board or you can buy a bareLearn More

DEF Sensor Simulator – Arduino UNO

Assembling a DEF Sensor Simulator Using an Arduino UNO Only basic electrical and DIY skills are required for the hardware assembly. The software installation in this procedure can be done from Windows. Before you begin, please click here to read an important compatibility notice regarding the ECM (Electronic Control Module, aka Engine Computer) and info on compatible DEF head connectors. If you run into difficulty post a comment at the bottom of this page. Please read throughLearn More

DEF Sensor Simulator

Background: DEF systems in modern diesel engines are key to reducing Nitrous Oxide (NOx) emissions  and protecting the environment.   The DEF system is a combination of software, hardware and DEF fluid that enable this important task.  Recently there has been a pandemic of failures affecting one of the elements of the DEF system called the DEF sensor.  The origins of this “DEF pandemic” are not  known for certain but the failures may be related toLearn More

Windows Defender

Windows Defender and Software Installation: Windows Defender is found on many Windows 10 computers along with other 3RD party anti-virus software.  When running “DEF Emulator Install Files (x32).exe” to install the Arduino programming files, Windows Defender (or other anti-virus program) will probably “complain”.   This is because the .exe program is an unrecognized .application.  Do not be alarmed. Windows Defender will show: Click on “More info” to continue the install process.  Another window will open askingLearn More

Fault Codes Explained

A modern diesel engine is a very complex device. Over the many years that they have been used there have been steady increases in power, reductions in fuel usage and significant reductions in harmful pollutants. Some claim the exhaust of a modern diesel engine can actually be cleaner than the air going into it! These improvements have required more and more sophisticated control systems. At the heart of the Cummins engines is the Electronic ControlLearn More
