System and method for spread-spectrum time-domain reflectometry and design data wire testing

A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to perform operations comprising:

• receiving a user selection of a vehicle, a first electrical connector, a connection pin of the first electrical connector, and a second electrical connector, to identify a wire segment of the vehicle;
• receiving wiring data indicating at least a length of the wire segment from a design database;
• receiving SSTDR data associated with the wire segment from an SSTDR device coupled to the connection pin of the first electrical connector;
• calculating a distance-to-fault based on the SSTDR data;
• comparing the distance-to-fault to the length of the wire segment;
• in response to the distance-to-fault being less than the length of the wire segment, generating fault data indicating a failure within the wire segment;
• and
• displaying the fault data at a user output device.

A method for wire connectivity testing comprising:

• receiving wiring data indicating at least a length of a wire segment from a design database;
• receiving spread-spectrum time-domain reflectometry (SSTDR) data associated with the wire segment from an SSTDR device coupled to an endpoint of the wire segment;
• calculating a distance-to-fault based on the SSTDR data;
• comparing the distance-to-fault to the length of the wire segment;
• in response to the distance-to-fault being less than the length of the wire segment, determining that a failure has occurred within the wire segment and generating fault data including an indication of a failure type and a failure position;
• and
• displaying the fault data at a user output device.
