BEFORE YOU BUY

Digital PDF only; no physical book or scan tool. Worksheets are static and printable. Practice readings are invented training examples, not actual scan screenshots or universal specifications. This workbook teaches diagnostic reasoning; it does not include terminal pinouts, installation steps or guaranteed diagnoses. Hybrid service and safety-system procedures are outside scope. Use the correct vehicle owner and service information.

Manufacturer examples cover specified GM and Ford vehicles plus a Honda hybrid context example. A described fault is not a diagnosis of your vehicle.
