DIAGNOSTICS FOR SMART SENSORS OF VEHICLES
First Claim
1. A method, comprising:
- receiving a result of a diagnostic test from a smart sensor of a vehicle at a first time;
retrieving, from memory, a sequence indicator pertaining to a second time in which the diagnostic test is expected to be completed by the smart sensor; and
providing a health assessment using the result via a processor, provided that the second time does not precede the first time.

Abstract
Methods, program products, and vehicles are provided for providing diagnostics for a smart sensor, such as a direct current (DC) converter, for a vehicle. A result of a diagnostic test is received from the smart sensor at a first time. A sequence indicator is retrieved from memory. The sequence indicator pertains to a second time in which the diagnostic test is expected to be completed by the smart sensor. A health assessment is provided using the result via a processor, provided that the second time does not precede the first time. The health assessments may be linked individually to a diagnostic trouble code, or may be grouped together and linked as a group to a diagnostic trouble code. Multiple smart sensor health assessments may be grouped and linked to diagnostic trouble codes.
