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 a plurality of preconditions required for a subsequent diagnostic test and determine if any currently valid preconditions in a current diagnostic test is needed for the subsequent diagnostic test;
a setting verifier configured to verify a state of each of the plurality of preconditions and the currently valid preconditions; and
a preparatory step formatter configured to provide a test step for each of the plurality of conditions that is in an invalid state.

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 preconditions, comprising the steps of:
-
determining the precondition required for a subsequent diagnostic test; determining if any currently valid preconditions in a current diagnostic test is needed for the subsequent diagnostic test; providing instructions to a user to make the precondition required for the subsequent diagnostic test valid if the precondition is not valid; and providing instructions to the user to make any of the currently valid preconditions invalid if the currently valid preconditions is not required by the subsequent diagnostic test. - View Dependent Claims (10, 11, 12, 13, 14, 15)
