Method and system for computer network implemented vehicle diagnostics
DCFirst Claim
1. An automotive code reader for diagnosing a vehicle having an onboard computer for generating diagnostic trouble code signals, the diagnostic trouble code signals being related to a vehicle status, the tool comprising:
- a connector for connecting to the onboard computer;
a connect button for electrically connecting the scan tool to the onboard computer;
a microprocessor disposed in the code reader, in electrical communication with the connector, for determining the presence of diagnostic trouble code signals as indicative of either a passed or problem status of the vehicle; and
a plurality of indicator lights in electrical communication with the microprocessor, the microprocessor being operative to selectively illuminate a first indicator light in response to receipt of diagnostic trouble code signals from the onboard computer, a second indicator light in response to a determination that no diagnostic code signals were received from the onboard computer, and a third indicator light in response to an inability to conclusively determine presence or absence of diagnostic trouble code signals in the onboard computer;
the selective illumination of one of the indicator lights proceeding in response to operation of the connect button, independent of user interaction with a visual interface.

Abstract
A method of diagnosing a status of a vehicle. The vehicle has an on-board computer for generating a diagnostic trouble code signal related to a passed or problem status of the vehicle. A portable code reader is connected to the on-board computer. Diagnostic trouble code signals are communicated from the on-board computer to the code reader. The code reader communicates to a personal computer respective ones of the diagnostic trouble code signals related to a problem status of the vehicle. The personal computer communicates the respective ones of the diagnostic trouble code signals from the personal computer to a remote computer. The remote computer is configured to correlate the diagnostic trouble code signals to problem description data for diagnosing the vehicle. Problem description data correlated to the respective ones of the diagnostic trouble code signals are communicated from the remote computer to the personal computer.

7. An automotive code reader for diagnosing a vehicle having an onboard computer for generating diagnostic trouble code signals, the diagnostic trouble code signals being related to a vehicle status, the tool comprising:
-
a connector for connecting to the onboard computer;
a connect button for electrically connecting the scan tool to the onboard computer; a microprocessor in electrical communication with the connector and operative to selectively generate a visual output signal representative of passed/failed/inconclusive status of the vehicle as determined from the absence/presence of diagnostic trouble code signals; and
a plurality of indicator lights in electrical communication with the microprocessor, the microprocessor being operative to illuminate a first indicator light in response to receipt of diagnostic trouble code signals from the onboard computer, a second indicator light in response to a determination that no diagnostic trouble code signals were recorded in the onboard computer, and a third indicator light in response to an inability to conclusively determine presence or absence of diagnostic trouble code signals in the onboard computer;
the selective illumination of one of the indicator lights proceeding in response to operation of the connect button, independent of user interaction with a visual interface. - View Dependent Claims (8, 9, 10, 11)
