Vehicle state tracking method and apparatus for diagnostic testing
First Claim
1. A diagnostic tool for use with a diagnostic test sequence, comprising:
- a precondition determiner configured to determine if a precondition is required for a subsequent diagnostic test;
a setting verifier configured to verify a current state of the precondition for the subsequent diagnostic test; and
a preparatory step formatter configured to provide instructions to make the precondition ready if required for the subsequent diagnostic test if the precondition is not ready for the subsequent diagnostic test.

Abstract
A vehicle state tracker tracks the state of a vehicle during a diagnostic test sequence to eliminate redundant steps between diagnostic procedures. The vehicle state tracker maintains a list of preconditions required for each diagnostic procedure, reads a current vehicle state from a memory register and verifies the current setting of the vehicle state corresponding to a specific precondition. If the precondition is required and the current setting is not valid, the state tracker further formats a test preparation step corresponding to the precondition for display to instruct a vehicle technician to satisfy the precondition. Otherwise, if the precondition is not required and the corresponding setting is valid, the state tracker formats an instruction to reverse the corresponding vehicle condition. The state tracker additionally receives feedback indicating when a precondition has been satisfied or the corresponding vehicle condition has been reversed, and updates the vehicle state in memory.

9. A computer implemented method of tracking a state of a precondition, comprising the steps of:
-
determining the precondition required for a subsequent diagnostic test, via a processor of the computer; determining if the required precondition is ready for the subsequent diagnostic test, via the processor; and providing instructions to a user to make the required precondition ready if the precondition is not ready, via the processor. - View Dependent Claims (10, 11, 12, 13)
