Modern cars are more computerized than ever, packed with infotainment and navigation systems, wireless connectivity, automatic software updates, advanced driver assistance features, and countless embedded controllers working behind the scenes. These technologies are designed to make driving safer, more comfortable, and more convenient. Yet while vehicle complexity has increased dramatically,…

This book provides a hands-on introduction to Controller Area Network (CAN) bus technology through practical projects using the Arduino Uno and the Raspberry Pi 4. By working with readily available CAN bus interface modules, readers learn how to design, build, debug, and test CAN-based systems without the need for specialized…
For diesel truck owners — whether you’re running a heavy-duty rig for work or simply maintaining a robust personal vehicle — having the right diagnostic tool can mean the difference between smooth highway miles and costly, time-consuming breakdowns. The ANCEL HD200 (sold on Amazon among other places) isn’t just another…
Please consider! The DEF Sensor Simulator is not an off-the-shelf device. It was originally created by a team of automotive engineers as a proof-of-concept solution for bypassing malfunctioning DEF sensors. The project consists of a parts list and open-source control code, and anyone using it must assemble and program the…
When working with the Controller Area Network (CAN) bus—whether in automotive, industrial automation, robotics, or embedded systems—you’ll quickly notice that most CAN connectors include a ground pin. At first, this may seem unnecessary because CAN uses differential signaling. If the data is transmitted as a difference between CAN-H and CAN-L,…
In the heavy-vehicle, mobile-machinery and industrial equipment world, the CAN bus remains a workhorse for on-board networks. But merely having physical CAN isn’t enough: what enables rich diagnostics, telematics and fleet data is the higher-layer protocol stack such as SAE J1939. The Teensy 4.1 Triple CAN Bus Board with Ethernet…
If you’re learning SAE J1939, you’ll quickly run into two acronyms that show up everywhere—in diagnostic messages, simulation tools, engine logs, and OEM documentation: SPN (Suspect Parameter Number) FMI (Failure Mode Identifier) Together, SPNs and FMIs explain what went wrong and how it went wrong.They form the core of every…
If you’re new to SAE J1939, one of the first things you’ll encounter is how heavy-duty vehicles report problems. They do this using standardized diagnostic messages, and the two most important are: DM1 — Active Diagnostic Trouble Codes DM2 — Previously Active Diagnostic Trouble Codes Understanding these two messages will…
If you’re looking to dive deep into the world of medium- and heavy-duty trucks—whether as a technician, a fleet maintenance manager, or a student of transportation technologies—this book is a standout resource. Heavy Duty Truck Systems offers one of the most comprehensive and up-to-date overviews of heavy vehicle systems I’ve…
Maintaining and troubleshooting heavy-duty trucks requires tools that go far beyond a basic automotive OBD-II reader. Whether you work with Freightliner, International, Paccar, Detroit Diesel, or Cummins engines, you need a scanner built specifically for the rugged and complex systems inside Class-4 through Class-8 diesel vehicles. The ANCEL HD601 J1939…
