Vehicle state tracking method and apparatus for diagnostic testing
First Claim
1. A computer-implemented method of tracking a state of a vehicle during a diagnostic test sequence, comprising:
- determining a precondition required for a diagnostic test;
reading a state register;
verifying a current first setting of the state register corresponding to the precondition;
determining a vehicle condition not required for the diagnostic test;
verifying a current second setting of the state register corresponding to the condition; and
specifying a second test preparation step related to the condition based on the second setting being valid.

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.

18. A diagnostic tool for tracking a state of a vehicle during a diagnostic test sequence, comprising:
-
a precondition determiner configured to determine a precondition required for a diagnostic test; a state reader configured to read a state register; a setting verifier configured to verify a state register; and a test preparation step specifier configured to specify a first test preparation step related to the precondition based on the first setting being invalid, wherein the precondition determiner is further configured to determine a vehicle condition not required for the diagnostic test, the setting verifier is further configured to verify a current second setting of the state register corresponding to the condition, and the test preparation step specifier is further configured to specify a second test preparation step related to the condition based on the second setting being valid. - View Dependent Claims (19, 20, 21, 22)
