A system for detecting anomalies in electrical wiring in a truck trailer. The system measures and compares current drawn from the truck tractor with the current drawn by a circuit at a particular trailer component or other location in the trailer wiring. If the two current measurements differ in excess of a predetermined threshold, the system can report a wiring anomaly. The location of the anomaly can then be determined by performing the operation for different trailer components thus testing multiple different branches of the trailer power distribution circuit, and using the results of these tests to determine that an anomaly is present, and possibly the location of the issue. The system may then send a notification to a remote computing device, to the truck tractor, or any combination thereof.

The invention relates to the technical field of device detection, and in particular provides a status detection method and device for a vehicle light signaling control device, and a vehicle, so as solve a technical problem of how to accurately and reliably detect an operating status of a vehicle light signaling control device. For this purpose, according to the method of an embodiment of the invention, a first resistance jump sequence of a currently detected position resistance may be obtained according to historical position resistance data and the currently detected position resistance; and then it is determined whether the vehicle light signaling control device has malfunctioned, according to a comparison result of the first resistance jump sequence and a preset second resistance jump sequence. By means of the foregoing steps, when a jump sequence of the position resistance is consistent with a normal resistance jump sequence, it may be determined that an actual position of a turn position shifting module is a position corresponding to this position resistance, which overcomes a defect of false position determination in the prior art caused by the inconsistency between a position corresponding to a resistance value detection result and an actual position of a light control lever.
