Abstract

A diagnostic tool and method are provided wherein the diagnostic tool can be configured to communicate a message including indicators to indicate the condition of the vehicle using a database and the DTCs present in the vehicle. The message can indicate for each DTC retrieved from the vehicle, the level of repair urgency and whether the vehicle can be driven without damaging the vehicle through one or both of a display and a speaker.

Claims

1. A diagnostic tool for diagnosing a vehicle, comprising:

a processor that processes a diagnostic data from the vehicle;

a memory that stores a database that is used to indicate a condition of the vehicle, wherein the database includes a plurality of stored diagnostic trouble codes (DTCs) and a level of urgency corresponding to each of the stored DTCs, wherein the corresponding level of urgency is determined from a pool of information related to vehicle service;

a connector interface that connects the diagnostic tool to a data link connector in the vehicle;

a signal translator that allows the diagnostic tool to communicate with the vehicle in at least one communication protocol;

a wireless communication circuit configured to communicate with a wireless device; and

a housing surrounding the processor, the memory, the connector interface, and the wireless communication circuit, wherein the wireless device is in communication with one or both of a display and a speaker in the vehicle to provide a user, an indicator that indicates the level of urgency corresponding to a retrieved DTC, and the indicator indicates an action corresponding to that level of urgency.

2. The diagnostic tool of claim 1, wherein the level of urgency informs the user when the vehicle should be serviced based on the stored DTC.

3. The diagnostic tool of claim 1, wherein the level of urgency includes three levels of urgency ranging from attention, caution and urgent repair needed.

4. The diagnostic tool of claim 2, wherein the level of urgency includes three levels of urgency ranging from a low level, a middle level and a highest level of urgency as to when the user should bring his vehicle in for repairs.

5. The diagnostic tool of claim 2, wherein the level of urgency includes three levels of urgency ranging from a low level, a middle level and a highest level of urgency to indicate to the user if the vehicle can still be driven without potential damage to the vehicle.

6. The diagnostic tool of claim 1 further comprising:

a user interface that includes a read button that also acts as a first scroll button and a back button that also acts as a second scroll button.

7. The diagnostic tool of claim 3, further comprising:

a user interface includes a read button that also acts as a first scroll button and a back button that also acts as a second scroll button.

8. The diagnostic tool of claim 1, wherein the display includes one or more displays of:

a vehicle, a smart phone device, a global positioning system, a tablet, a personal laptop computer, and a PDA.

9. The diagnostic tool of claim 8, wherein the vehicle'"'"'s display include one or more of:

a vehicle'"'"'s navigation screen, a head up display, a side mirror indicator, a rear view indicator, and an instrument panel indicator.

10. The diagnostic tool of claim 1, wherein the wireless communication circuit is configured to be in wireless communication with a vehicle'"'"'s onboard computer.

11. A diagnostic tool for diagnosing a vehicle, comprising:

a processor that processes a diagnostic data from the vehicle;

a memory that stores a database that is used to indicate a condition of the vehicle, wherein the database includes a plurality of stored diagnostic trouble codes (DTCs) and a level of urgency corresponding to each of the stored DTCs;

a connector interface that connects the diagnostic tool to a data link connector in the vehicle;

a signal translator that allows the diagnostic tool to communicate with the vehicle in at least one communication protocol;

a wireless communication circuit configured to communicate with an onboard computer system of the vehicle; and

a housing surrounding the processor, the memory, the connector interface, and the wireless communication circuit, wherein the wireless communication circuit is in wireless communication with one or both of a display and a speaker in the vehicle to provide a user, an indicator that indicates the level of urgency corresponding to a retrieved DTC matching the stored DTC, and the indicator indicates an action corresponding to that level of urgency.

12. The diagnostic tool of claim 11, wherein the wireless communication circuit is also in communication with one or more of:

a smart phone device, a global positioning system, a tablet, a personal laptop computer, and a PDA.

13. The diagnostic tool of claim 11, wherein the display includes one or more of:

a vehicle'"'"'s navigation screen, a head up display, a side mirror indicator, a rear view indicator, and an instrument panel indicator.

14. The diagnostic tool of claim 13, wherein the wireless communication is one of a personal area network (PAN) or a local area network (LAN) communication.

15. A method of indicating an urgency repair level of a vehicle, comprising:

allowing a communication between a diagnostic tool and a data link connector in the vehicle, wherein the diagnostic tool communicates an indicator that indicates a level of urgency related to a repair condition of the vehicle based on stored diagnostic trouble codes (DTCs), the level of urgency determined from a pool of information related to vehicle service;

retrieving DTCs stored in a vehicle diagnostic computer; and

providing to a user, through one or both of a speaker and a display, the level of urgency of repair condition for each DTC retrieved that corresponds to the stored DTCs, wherein the level of urgency takes the form of multiple levels of urgency and the indicator also recommends an action corresponding to that level of urgency.

16. The method of claim 15, wherein the multiple levels of urgency includes three levels of urgency ranging from attention, caution and urgent repair needed.

17. The method of claim 15, wherein retrieving the DTC is automatic when the diagnostic tool is connected to the vehicle and the vehicle is powered on.

18. The method of claim 15, wherein when the retrieving step fails, the diagnostic tool will toggle between a first message and a second message on the display.

19. The method of claim 15, wherein the providing step further comprises one or both of displaying on the display and playing through the speaker the corresponding DTC with the urgency indicator.

20. The method of claim 15, wherein each DTC will have its own corresponding urgency indicator.
