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.

Claims

1. A method of displaying automotive diagnostic information comprising:

connecting a code reader to a vehicle computer;

communicating monitor status information and trouble codes to the code reader from the vehicle computer;

selectively illuminating monitor icons on the code reader that are supported by the vehicle being tested;

displaying status of the supported monitors;

displaying trouble codes communicated from the vehicle computer; and

displaying trouble code descriptors corresponding to the displayed trouble code.

2. The process as recited in claim 1 wherein the trouble code descriptors are generated independent of any user input upon receipt of the trouble code.

3. The method as recited in claim 2 wherein the trouble code descriptors are generated independent of any user input to identify the type of vehicle being tested.

4. The method as recited in claim 1 wherein the selective illumination of supported monitors is implemented independent of any user input identifying the type of vehicle being tested.

5. The process as recited in claim 1 wherein the status of all supported monitors is displayed in a single display.

6. The process as recited in claim 1 wherein all diagnostic display functions are displayed in a single display.

7. The process as recited in claim 1 wherein all display functions are operative independent of any manual input to identify the type of vehicle being tested.
