1. A hand-held diagnostic display device that facilitates automatically verifying mandated system presence and status on a commercial vehicle, comprising:
- an interface configured to couple the diagnostic display device to a vehicle data bus and via which vehicle status information is received;
a computer-readable medium that stores a vehicle identification number (VIN) lookup table that cross references VIN numbers to mandated systems;
a processor configured to;
retrieve a VIN from a vehicle to which it is coupled;
perform a table lookup on the vehicle identification number (VIN) lookup table to identify one or more systems mandated to be on the vehicle as of a manufacture date of the vehicle as determined from the retrieved VIN;
query the data bus to verify the presence and operational status of the identified mandated systems;
output to a display presence and status information for each mandated system; and
wherein the display comprises a plurality of light emitting diodes (LED), including at least one presence LED that indicates that one or more mandated systems is detected on the data bus, and at least one status LED that indicates operational status of the one or more detected systems.

Abstract
A diagnostic display device is coupled to a vehicle data bus and receives vehicle identification information which is used to identify one or more expected onboard systems installed on the vehicle. Expected systems are queried to determine that they are present and operating properly. Presence and operation status information are stored and/or presented to a user to facilitate automated vehicle system inspection.

10. A method of automatically verifying mandated system presence and status on a commercial vehicle using a hand-held diagnostic display device, comprising:
-
retrieving a vehicle identification number (VIN) from a vehicle via a vehicle data bus; performing a table lookup on the vehicle identification number (VIN) lookup table to identify one or more systems mandated to be on the vehicle as of a manufacture date of the vehicle as determined from the VIN; querying the data bus to detect and verify the presence and operational status of the identified mandated systems; displaying presence and status information for each mandated system; and wherein displaying the presence and status information comprises selectively illuminating a plurality of light emitting diodes (LED), including at least one presence LED that indicates that one or more mandated systems is detected on the data bus, and at least one status LED that indicates the operational status of the one or more detected systems. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 27)

18. An apparatus that facilitates automatically verifying mandated system presence and status on a commercial vehicle, comprising:
-
means for retrieving a vehicle identification number (VIN) from a vehicle via a vehicle data bus; means for performing a table lookup on the vehicle identification number (VIN) lookup table to identify one or more systems federally mandated to be on the vehicle as of the manufacture date of the vehicle as determined from a vehicle manufacture date indicated by the VIN; means for querying the data bus to detect and verify the presence and operational status of the identified mandated systems; and means for displaying presence and status information for each mandated system; wherein the means for displaying comprises a plurality of light emitting diodes (LED), including at least one presence LED that indicates that one or more mandated systems is detected on the data bus, and at least one status LED that indicates operational status of the one or more detected systems. - View Dependent Claims (28)

19. A hand-held diagnostic display device that facilitates automatically verifying electronic control system presence and status on a commercial vehicle, comprising:
-
an interface configured to couple the diagnostic display device to a vehicle data bus and via which vehicle status information is received; a computer-readable medium that stores a vehicle identification number (VIN) lookup table that cross references VIN numbers to specified electronic control systems; a processor configured to; retrieve a VIN from a vehicle to which it is coupled; perform a table lookup on the vehicle identification number (VIN) lookup table to identify one or more electronic control systems specified to be on the vehicle as of a vehicle manufacture date indicated by the VIN; query the data bus to verify the presence and operational status of the identified electronic control systems; and output presence and status information for each electronic control system; wherein the output comprises a plurality of light emitting diodes (LED), including at least one presence LED that indicates that one or more electronic control systems is detected on the data bus, and at least one status LED that indicates operational status of the one or more detected electronic control system. - View Dependent Claims (20, 21, 22, 23, 24, 25, 29)
