First Claim
Patent Images
1. A 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 for a vehicle to which it is coupled;
perform a table lookup to identify one or more systems mandated to be on the vehicle as a function of the manufacture date of the vehicle;
query the data bus to verify the presence and operational status of the mandated systems; and
output to a display presence and status information for each mandated system.

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.
