An apparatus including a transmission mechanism in a power transfer path between a drive source and wheels; an oil pressure control device supplying lubricating oil to the transmission mechanism; and a control part outputting an electrical instruction to increase a flow rate of the supplied lubricating. When the control part outputs an electrical instruction to the oil pressure control device to increase a flow rate of lubricating oil supplied to the transmission mechanism, and determines that the flow rate of lubricating oil supplied to the transmission mechanism from the oil pressure control device does not increase as indicated by the electrical instruction (time t1), the control part considers that the oil pressure control device is in an abnormal state, and can impose a limitation that an absolute value of torque of the transmission mechanism transferred between the wheels and the drive source be reduced (time t1-t5).

In an embodiment, a vehicle makes a determination, during a second ignition-on cycle of the vehicle, that a trailer brake output circuit of the vehicle was operated during a first ignition-on cycle of the vehicle preceding the second ignition-on cycle. In response to making the determination, the vehicle presents a query, via a user interface of the vehicle, whether to operate the trailer brake output circuit according to a previously-used trailer profile according to which the trailer brake output circuit was operated during the first ignition-on cycle preceding the second ignition-on cycle. The vehicle receives a reply, associated with the query, via the user interface and, in response to receiving the reply, operates the trailer brake output circuit based on the reply.
