Abstract

A method of displaying automotive diagnostic information is disclosed comprising connecting a code reader to a vehicle computer and communicating monitor status information and trouble codes to the code reader. Only those monitor functions that are supported by the vehicle are illuminated on the code reader, along with their status. Trouble codes communicated from the vehicle are also displayed, along with trouble code descriptors. All display functions are operative independent of any manual input to identify the type of vehicle being tested.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001](Not Applicable)STATEMENT RE: FEDERALLY SPONSORED RESEARCH / DEVELOPMENT[0002](Not Applicable)BACKGROUND OF THE INVENTION[0003]The present invention relates generally to methods and systems for diagnosing a vehicle, and more particularly to displaying diagnostic fault codes generated by automobile computer systems.[0004]Modern motor vehicles include a computer control system. The main purpose of the vehicle computer control system is to provide maximum engine performance with the least amount of air pollution and the best fuel efficiency possible. The computer control system consists of the on-board computer and related electronic control devices (sensors, switches, and actuators). The control devices may control various systems and / or subsystems within the vehicle. These electronic control devices send information to the on-board computer about such parameters as the temperature and density of the outside air, the speed of the engine, the ...
