Abstract

An engine diagnostic system includes an engine and a control system having a controller operatively connected to the engine. A monitoring system has a measurement device operatively connected to the engine. A diagnostic system is operatively connected to the engine. A communication system is configured to send and receive data from a remote location. The diagnostic system is configured to implement a non-starting engine diagnostic procedure, at least a portion of which is performed while the engine is cranking, and to transmit data generated during the engine diagnostic procedure to the remote location through the communication system.

First claim

What is claimed:

1. An engine diagnostic system comprising:
an engine and a control system having a controller operatively connected to the engine;
a monitoring system having a measurement device operatively connected to the engine;
a diagnostic system operatively connected to the engine; and
a communication system configured to send and receive data from a remote location,
wherein the diagnostic system is configured to implement a non-starting engine diagnostic procedure, at least a portion of which is performed while the engine is cranking, and to transmit data generated during the engine diagnostic procedure to the remote location through the communication system,
wherein the communication system is configured to transmit data to a data processing system and the data processing system is configured to analyze the data and provide a recommendation based on the analyzed data, and
wherein the recommendation identifies a reduced number of potential sources of a problem from a maximum amount of potential sources.

2. The engine diagnostic system of claim 1 , wherein the diagnostic system is configured to implement a harness diagnostic test.

3. The engine diagnostic system of claim 2 , wherein the data includes diagnostic trouble codes.

4. The engine diagnostic system of claim 1 , wherein the non-starting engine diagnostic procedure monitors and records information from engine components in a non-starting engine category.

5. The engine diagnostic system of claim 1 , wherein the diagnostic system is configured to record data after the engine begins cranking.

6. The engine diagnostic system of claim 1 , wherein the remote location includes a communication module configured to send a signal to initiate the non-starting engine diagnostic procedure.

7. The engine diagnostic system of claim 1 , wherein the engine is connected to a vehicle and operatively connected to one or more ground engaging elements.

8. The engine diagnostic system of claim 1 , wherein the communication system includes a telematics system.

9. A method of diagnosing a non-starting engine comprising:
sending a signal to a diagnostic system operatively connected to an engine, the signal sent through a communication system configured to send and receive data from a remote location;
implementing a non-starting engine diagnostic procedure in response to the signal, wherein at least a portion of the non-starting engine diagnostic procedure is performed while the engine is cranking;
obtaining data generated during the non-starting engine diagnostic procedure related to the non-starting engine;
transmitting the data to the remote location through the communication system; and
receiving the data at the remote location and analyzing by a data processing system, wherein the data processing system is configured to analyze the data and provide a recommendation based on the analyzed data, and wherein the recommendation identifies a reduced number of potential sources of a problem from a maximum amount of potential sources.

10. The method of claim 9 , wherein the diagnostic system is configured to record one or more engine parameters during the non-starting engine diagnostic procedure.

11. The method of claim 9 , further comprising a user cranking the engine during the non-starting engine diagnostic procedure for a set period of time.

12. The method of claim 11 , further comprising issuing an error if the engine is being cranked after the set period of time.

13. The method of claim 11 , further comprising performing a harness diagnostic test during the non-starting engine diagnostic procedure when the engine is not being cranked.

14. The method of claim 9 , wherein the data includes diagnostic trouble codes.

15. The method of claim 9 , further comprising presenting the recommendation to a technician.

16. The method of claim 9 , wherein the signal is sent from the remote location.
