PROBLEM TO BE SOLVED: To provide a method of monitoring for a state of an electric wiring and connection, and provide a control device for a vehicular transmission system. SOLUTION: In control for a vehicular transmission containing electric devices, such as electric motors 36 and 38 and solenoid control valves 24 and 30 selectively operated or non-operated by connection of thereof to a power supply, a voltage monitor detects a voltage drop between the power supplies regarding an electric device by which a voltage monitor is properly operated and decides whether electrical connection is in a trouble state or not. The controller 50 operates electric devices brought into given combination and decides such that the electric devices are respectively properly functioned, and detects a total voltage drop between the power sources occurring due to operation of the electric devices in the combination, calculates a reference value equal to a total of a predicted voltage drop regarding the operated power source, compares the detected voltage drop with a reference value, and decides that the electrical connection is in a trouble state when the detected voltage drop exceeds the reference value. |
