212 Pages • Fully Illustrated • Automotive & Heavy-Duty • Professional ECU Reference Guide

The Complete Illustrated Guide to ECU Electronics, Components & Circuit Diagnosis.

This manual starts with the essential building blocks of ECU electronics — including resistors, capacitors, diodes, transistors, MOSFETs, inductors, ferrite beads, and crystal oscillators — before moving into detailed real-world ECU circuit-board analysis.

Learn how to identify electronic components, understand their function inside an ECU, use a multimeter for component testing, recognize power-supply and driver circuits, and locate critical areas such as injector drivers, CAN communication circuits, boost stages, voltage regulators, current-sensing circuits, memory, CPUs, and protection components.

The practical ECU section includes detailed board overviews and internal component identification for systems including:

Bosch EDC7 • EDC16C39 • EDC16UC40 • EDC16C8 • EDC17C55 • EDC17CV44 • Cummins CM800 • CM2220 • CM2880 • Hino Denso C31 • Delphi DCM3.2 • Weichai • Xichai • Yuchai • EControls and more.

Each illustrated example helps you understand how real ECU boards are organized and where important electronic circuits and components are located.

For automotive technicians, ECU repair specialists, diagnostic professionals and electronics enthusiasts who work on car, commercial-vehicle, diesel and heavy-duty ECUs and want a practical visual reference for board-level diagnosis.
