ABSTRACT:
An automotive electrical system including a wiring harness incorporates a dedicated test line passing through critical connectors and components for allowing detection and isolation of improperly connected connectors. The dedicated test line can feed through expansion connectors, termination connectors, and junction blocks. A respective impedance is connected between the dedicated test line and ground at each respective connector. Connector fault detection and isolation is achieved by measuring the total impedance presented at the beginning of the test line. The measured impedance uniquely identifies the locations of any improperly connected connectors.
