Quick check vehicle diagnostics
First Claim
1. A vehicle diagnostic system comprising:
- a storage device in communication with a plurality of vehicle subsystem control modules;
a diagnostic unit in communication with said storage device; and
a display in communication with said diagnostic unit to simultaneously display a plurality of keys, each of said keys representative of a fault condition for one of said plurality of vehicle subsystem control modules, each of said keys comprsing an alphanumeric description of said fault condition associated therewith.

Abstract
A vehicle data storage system in communication with a diagnostic unit provides a “quick fault” screen which summarizes event data stored within a storage device of the vehicle data storage system. The “quick fault” screen displays a plurality of keys organized in matrix format to display an overview of fault conditions through animation and/or coloring of each key in response to the event data stored within the storage device. By selecting any animated/colored key, a more detailed representation of the event data stored in the storage device for the particular fault condition is presented. The detailed subsystem screen presents the event data recorded within the storage device in a graphical and/or tabulation format showing associate subsytem parameters over time.

14. A method of displaying vehicle diagnostic data comprising the stops of:
-
(1) communicating with a vehicle storage device in communication with a plurality of vehicle subsystem control modules;
(2) simultaneously displaying a plurality of keys, each of the plurality of keys comprising an alphanumeric description of a fault condition associated therewith, each of said keys associated with one of said plurality of vehicle subsystem control modules;
(3) identifying the fault condition associated with each of the plurality of vehicle subsystem control modules; and
(4) modifying each of the plurality of keys in response to each of the plurality of keys associated fault condition identified in said step (3). - View Dependent Claims (15, 16, 17, 18, 21, 22, 23, 24)
storing a plurality of vehicle operating conditions relative to time in a buffer; and
storing the vehicle operating conditions from the buffer to the vehicle storage device in response to a triggering event determined by one of the plurality of vehicle subsystems.

21. A method as recited in claim 14, wherein said step (4) further comprises displaying a diagnostic code upon each of the plurality of keys in response to the fault condition.
-
22. A method as recited in claim 14, further comprising the steps of:
-
(a) selecting one of the plurality of keys; and
(b) displaying a detailed subsystem screen associated with the fault condition associated with the selected key of said step (a).
-
-
23. A method as recited in claim 22, wherein said step (b) further comprises displaying subsystem data associated with the fault condition from the vehicle storage device.
-
24. A method as recited in claim 22, wherein said step (b) further comprises displaying subsystem data associated with the fault condition from the vehicle storage device over a predetermined time period.
