Abstract

The present document describes a system for offline testing of an installed wiring harness, comprising: at least a first and a second testing module, having: a communication module for receiving test specifications and for sending test measurements; testing equipment for generating the test measurements from the test specifications; each of the first and second testing modules being adapted for connection at a connection point in the wiring harness; a central network management module, having: a communication module for providing the test specifications to the testing modules and for receiving the test measurements; and a test management module for controlling the testing modules.

Claims

1. A method for testing an installed wiring harness, comprising:

providing a signal source testing module at a first connection point in the wiring harness;

providing a measurement termination testing module at a second connection point in the wiring harness;

providing a central management module for controlling the testing modules to coordinate the testing modules to send testing signals from the first connection point to the second connection point, after disconnecting electrical power between the connection points, for performing tests and recording test measurements of the installed wiring harness; and

the signal source testing module and measurement termination testing module for sending the test measurements to the management module.

2. A system for offline testing of an installed wiring harness, comprising:

at least a first and a second testing module, having;

a communication module for receiving test specifications and for sending test measurements;

testing equipment for generating the test measurements from the test specifications; and

each of the first and second testing modules being adapted for connection at a connection point in the wiring harness;

a central network management module, having;

a communication module for providing the test specifications to the testing modules and for receiving the test measurements; and

a test management module for controlling the testing modules.

3. The system as claimed in claim 2, further comprising storage means for storing the test specifications and the test measurements, and further wherein the test management module is for retrieving the test specifications from the storage means.

4. A system as claimed in claim 2, wherein the storage means further comprises wiring harness historical data and wherein the central network management module further comprises:

an analysis module for providing a diagnostic and recommendations based on the wiring harness historical data and the test measurements data.

5. A system as claimed in claim 2, wherein the testing equipment comprises at least one of:

circuit switch and polarity analysis module, standing wave ratio test module, TDR test module and spectrum impedance test module.

6. A system as claimed in claim 2, further comprising a report module for providing a report of the test measurements of the installed wiring harness.

7. The system as claimed in claim 2, wherein at least one of the first and second testing modules comprises a signal generator for generating a testing signal and a multiplexer for routing the testing signal to one of a plurality of wires connected to the wiring harness connection point.

8. The system as claimed in claim 7, wherein at least one of the first and second testing modules comprises test equipment for generating the test measurements from the routed test signal.
