SYSTEMS FOR DETECTING ELECTRICAL FAULTS IN A VEHICLE

摘要

Systems are provided to determine a location of an electrical fault in an electrical system of a vehicle. A test apparatus can include a control unit and a plurality of scan circuits. The control unit is configured to electrically couple the plurality of scan circuits to the electrical system and trigger the plurality of scan circuits to pass electrical signals to the electrical system. Each scan circuit is configured to detect a presence of an electrical fault in the electrical system based on an electrical signal passed. Each scan circuit provides information indicative of a location of the electrical fault in the electrical system, when detected, to the control unit.

主权项

1. A system, comprising:
a fault location system having plural scan circuits respectively electrically connected to plural electrical circuits in an electrical system of a vehicle and configured to apply respective electrical signals to the plural electrical circuits; and a control unit configured for electrical communication with the plural scan circuits in the vehicle, wherein the plural scan circuits are further configured to receive secondary signals respectively generated by the plural electrical circuits responsive to the electrical signals applied by the plural scan circuits to the plural electrical circuits, and to communicate information of the secondary signals that are received to the control unit, wherein the control unit is configured to determine a location of an electrical fault in the electrical system based on the information received from the plural scan circuits, and wherein the control unit is further configured to control at least one electronic device based on the location of the electrical fault that is determined.
