ECU Repair Helper E-Book is a technical reference for ECU electronics and bench level diagnostics. It focuses on practical identification of common circuit components, typical failure modes, and model specific notes across multiple OEM ECU families. Use it as a workshop companion for troubleshooting, inspection planning, and repair documentation.
The guide is structured like a help viewer with a left side navigation tree. Below is a clean outline of the sections shown in the contents pane, kept as a readable tree to capture the manual keywords.
