TABLE OF CONTENTS Authors Note: To keep the glossary to a reasonable size, I decided to limit the entries to useful acronyms that are specified by the society of automotive engineers (SAE) and on-board diagnostic version two (OBD2) recommendations. I have provided free access to online glossaries (UK, US and Spanish) that include several thousand words. http://www.automotive-technology.co.uk
Two key words never to forget:
| Symptom(s): | What the user/operator/repairer of the system (vehicle or whatever) notices |
| Fault: | An error in the system that causes symptom(s) |
