The invention discloses a switch solenoid valve fault diagnosis method, device and equipment, a storage medium and a product, and relates to the technical field of vehicle detection, and the method comprises the steps: sending a detection instruction to a to-be-detected vehicle, so as to detect a cooling and lubricating loop of a cooling and lubricating system in the to-be-detected vehicle; when the cooling and lubricating loops pass the detection, the current driving working condition of the to-be-detected vehicle is obtained; the switch solenoid valve of the to-be-detected vehicle is diagnosed based on the current driving working condition, whether the switch solenoid valve has faults or not is judged based on the diagnosis result, and the faults of the switch solenoid valve comprise valve element clamping stagnation, coil short circuit and coil open circuit. When the cooling and lubricating loop of the cooling and lubricating system in the to-be-detected vehicle is determined to be normal, the on-off solenoid valve of the to-be-detected vehicle is diagnosed based on the current driving working condition of the to-be-detected vehicle, so that whether the on-off solenoid valve has a fault or not is judged, and fault diagnosis can be accurately performed on the on-off solenoid valve in the face of a complex oil way.
