From Advanced Automotive Fault Diagnosis, Second Edition

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)

OBD2/SAE acronyms

ABS

antilock brake system

A/C

air conditioning

AC

AIR

secondary air injection

A/T

AP

Products & Services
RF Frequency Multipliers
RF frequency multipliers are nonlinear devices that produce an output signal with a frequency that is larger than the frequency of a corresponding input signal by a predetermined factor.
Frequency Meters
Frequency meters are instruments that provide analog outputs as frequencies that vary as a function of the applied input. They display values on a dial, usually with a needle or moving pointer.
IC Power Supplies
IC power supplies are manufactured as integrated circuits.
Voltage-to-Frequency Converter Chips
Voltage-to-frequency converter chips provide a signal frequency output as a function of an analog input voltage.
RF Generators
RF generators and high frequency power supplies provide the power required for plasma generation, induction heating, and radar or communications applications.
