Abstract

A device includes a processor in communication with a first port, a second port and a third port. The first port is configured to communicate via a diagnostic cable with an electronic control unit of a vehicle. The diagnostic able cable has a first end configured to connect to a vehicle port and a second end configured to connect to the first port. The processor is configured to selectively test the communication capability of the diagnostic cable when the first end of the diagnostic cable is connected to the third port and the second end of the diagnostic cable is connected to the first port.

Claims

1. A vehicle communication device comprising:

a processor in communication with a first port, a second port and a third port;

the first port being configured to communicate via a diagnostic cable with an electronic control unit of a vehicle, the cable having a first end configured to connect to a vehicle port, the vehicle port being in communication with the electronic control unit of the vehicle, the cable having a second end configured to connect to the first port;

the second port configured to communicate with an auxiliary device;

the third port configured to connect to the first end of the diagnostic cable; and

wherein the processor is configured to selectively test the communication capability of the diagnostic cable when the first end of the diagnostic cable is connected to the third port and the second end of the diagnostic cable is connected to the first port.

2. The device of claim 1, wherein the third port is a female connector.

3. The device of claim 1, wherein the third port is a female OBD-II connector.

4. The device of claim 1, wherein the first port is in communication with the third port.

5. The device of claim 1, wherein the auxiliary device comprises an external tester.

6. The device of claim 1, wherein the auxiliary device comprises a computing device.

7. The device of claim 6, wherein the processor is configured to translate a first communication language of the vehicle to a second communication language configured for being received by the computing device.

8. The device of claim 6, wherein the computing device comprises an emissions testing device.

9. The device of claim 1, wherein the second output port comprises an Ethernet or USB port and the first output port comprises an ODB-type port.

10. The device of claim 1, wherein the processor is further configured to:

send a known signal from the first port to the third port when the first end of the diagnostic cable is connected to the third port and the second end of the diagnostic cable is connected to the first port;

determine that the diagnostic cable is defective if the known signal is not received by the third port from the first port.

11. The device of claim 1, wherein the processor is further configured to perform a continuity test of the diagnostic cable when the first end of the diagnostic cable is connected to the third port and the second end of the diagnostic cable is connected to the first port
