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.
