Patent Images
1. An adaptive cable for use with a vehicle diagnostic tool, comprising:
- a complex programmable logic device adapted to receive instructions from the vehicle diagnostic tool;
a first multiplexer adapted to receive instructions from the complex programmable logic device to configure its connections for a vehicle communication protocol;
a first cable to connect the adaptive cable to the vehicle diagnostic tool at a first end and to communicate with the complex programmable logic device at a second end;
a second cable to connect to a data link connector in a vehicle at a first end and to communicate with the first multiplexer at a second end;
a communication protocol module that communicates in various communication protocols and communicates with the multiplexer; and
a housing that houses the first multiplexer, a portion of the first cable, a portion of the second cable, the communication protocol module and the complex programmable logic device.

Abstract
An apparatus and method are provided that allow a scan tool to communicate with a data link connector in a vehicle. A cable that can automatically multiplex its connections in order to make the appropriate connections between the scan tool and a data link connector based on a communication protocol of the vehicle under test. This allows the scan tool to communicate with the data link connector regardless of the pins being used by the communication protocol of the vehicle.
