Abstract

A system and method for determining work procedures through correlated symptoms are provided. The system made up of a diagnostic authoring apparatus for constructing and managing a diagnostic database. Information is stored in the diagnostic database that identifies vehicles that have the tendency to display certain symptoms in correlation with particular problems. These problems in the vehicles generally have a common solution for that type of vehicle. The problem may be common enough to check for a symptom preemptively, possibly before the vehicle owner is aware of it, or even prior to the manifestation of the symptom. The problem may warrant action taken to fix or avoid the problem. The system and method may associate and mark a problem with a preemptive symptom so a vehicle service/repair professional may be presented with the proper way to handle the associated problem for a particular vehicle.

Claims

1. A method for determining a work sequence for a vehicle through correlated symptoms, comprising the steps of:

storing a diagnostic database including symptoms for a particular vehicle type, the diagnostic database communicatively connected to a diagnostic apparatus;

correlating a symptom, a problem, a vehicle type, the work sequence, and a preemptive symptom flag in the diagnostic database to create a grouping;

flagging the grouping in the diagnostic database with the preemptive symptom flag to indicate the symptom in the grouping is a preemptive symptom and distinguishing the preemptive symptom from other symptoms;

entering vehicle information for the vehicle into the diagnostic apparatus;

matching the vehicle information entered in the diagnostic apparatus with the vehicle type in the diagnostic database;

identifying the preemptive symptom correlated with the matched vehicle type in the diagnostic database; and

presenting a user with the preemptive symptom and the work sequence indicated for the identified preemptive symptom on a display of the diagnostic apparatus.

2. The method of claim 1, wherein identifying the preemptive symptom further comprises the step of checking the grouping for the preemptive symptom flag.

3. The method of claim 1, further comprising the step of assigning priority information to the grouping containing the preemptive symptom indicating relative importance in comparison to other work sequences for the vehicle.

4. The method of claim 1, further comprising the step of updating the diagnostic database when additional symptoms are found for the vehicle type.

5. The method of claim 1, wherein presenting the user with the preemptive symptom and the work sequence occurs even though the preemptive symptom is not currently present in the vehicle.

6. The method of claim 1, further comprising the step of adding new groupings to the diagnostic database.

7. The method of claim 1, further comprising the step of manually updating the diagnostic database and adding new groupings to the diagnostic database.

8. The method of claim 1, further comprising the step of automatically updating the diagnostic database and adding new groupings to the diagnostic database.

9. A diagnostic apparatus that determines work procedures for a vehicle through correlated symptoms, comprising:

a memory configured to store a diagnostic database, the diagnostic database having correlated in a grouping of information a symptom, a problem, a vehicle type, the work procedure, and a preemptive symptom flag configured to indicate whether the symptom is a preemptive symptom;

an input configured to receive vehicle information;

a processor configured to match the vehicle information entered into the diagnostic apparatus with the vehicle type in the diagnostic database, identify the preemptive symptom correlated with the matched vehicle type in the diagnostic database, and retrieve information from the diagnostic database, the information including the preemptive symptom and the work procedure; and

a display configured to present a user with the information retrieved from the diagnostic database.

10. The apparatus of claim 9, wherein the problem includes a vehicle component, system, or failure mode.

11. The apparatus of claim 9, wherein the symptom includes a textual description of the symptom or a failure code.

12. The apparatus of claim 9, wherein the vehicle type includes a single vehicle or a range of vehicles.

13. The apparatus of claim 9, wherein the work procedure includes a diagnostic, repair, or service sequence.

14. The apparatus of claim 9, wherein the vehicle information includes a vehicle identification information, a vehicle condition information, or an environmental condition information.

15. The apparatus of claim 9, wherein the grouping of information further comprises priority information correlated to the preemptive symptom.

16. A diagnostic tool for determining a work sequence through correlated symptoms, comprising:

means for storing a diagnostic database, the diagnostic database having correlated in a grouping a symptom, a problem, a vehicle type, the work sequence, and a preemptive symptom flag configured to indicate whether the symptom is a preemptive symptom;

means for inputting vehicle information;

means for processing that matches the vehicle information entered into the diagnostic tool with the vehicle type in the diagnostic database, identifies the preemptive symptom correlated with the matched vehicle type in the diagnostic database, and retrieves information from the diagnostic database, the information including the preemptive symptom and the work sequence; and

means for displaying to a user the information retrieved from the diagnostic database.

17. The diagnostic means of claim 16, wherein the grouping further comprises priority information correlated to the grouping containing the preemptive symptom.

18. A diagnostic authoring apparatus to determine work procedures for a vehicle through correlated symptoms, comprising:

a diagnostic database built by the authoring apparatus, the diagnostic database having correlated in a grouping of information a symptom, a problem, a vehicle type, the work procedure sequence, and a preemptive symptom flag configured to indicate whether the symptom is a preemptive symptom;

an input configured to receive the information for the diagnostic database;

a processor configured to transfer the information from the input to the diagnostic database; and

a memory configured to store the diagnostic database.

19. The apparatus of claim 18, wherein the processor is configured to run software stored on the memory and to automatically update the diagnostic database upon receiving new information.

20. The apparatus of claim 18, wherein the grouping further comprises priority information correlated to the preemptive symptom.
