The connector (10) includes a housing (20) connectable to a mating housing (80) disposed on a solenoid (40), and a swing support portion (61) arranged on a side where a valve body (50) to be mounted with the solenoid (40) is located and configured to support the housing (20) swingably in a direction intersecting with a connecting direction and cause the housing (20) to be connected to the mating housing (80) as the solenoid (40) is mounted into the valve body (40).

A plurality of electrical connection structures are provided. Each of the electrical connection structures includes a plurality of electrical wires each having a wiring portion and an electrical connection portion directly or indirectly electrically connected to an electromagnetic valve (a control unit) at an end of the wiring portion, and wiring plates on which wiring portions are arranged. Between the electrical connection structures disposed next to each other, another end of the wiring portion of the electrical connection structure establishes an electrical connection relation with the another end of the wiring portion of the electrical connection structure. Between the electrical connection structures disposed next to each other, a movable portion capable of changing a relative positional relation therebetween is provided.

A connector module includes an electrical connection structure including: a plurality of electrical wires; and a wiring plate on which the electrical wires are wired. Each of the electrical wires is coated with an insulating coating, and includes: a wiring portion wired on the wiring plate; and an electrical connection portion to be physically and electrically connected to a counterpart electrical connection portion. The wiring plate includes a surrounded recess-shaped portion. The electrical connection portion and the counterpart electrical connection portion are arranged in the recess-shaped portion and are formed such that a physical and electrical connection part thereof is housed in the recess-shaped portion. The connection part is covered with an insulating member.

An actuator diagnostic apparatus is provided for an electronic control unit of a vehicle. The actuator diagnostic apparatus of the electronic control unit for a vehicle is characterized by containing: a high-side driver which drives an actuator from a high-side; an output voltage sensing unit which senses an output voltage of the high-side driver; a low-side driver which drives the actuator from a low-side; a pull-down switch which pulls down an input voltage of the high-side driver; a shutdown driver which actuates the pull-down switch; and a diagnostic control unit which diagnoses shutdown of the actuator upon receiving an input of the output voltage from the output voltage sensing unit after respectively actuating the high-side driver, the low-side driver, and the shutdown driver in accordance with a shutdown diagnosis order.

Provided is a load drive device with high stability (linearity) and a control method thereof capable of continuing a normal operation without stopping the load drive device even when a reverse current is temporarily detected with a specific inductive load in the load drive device in which a plurality of inductive loads are connected in parallel.

A transmission housing includes a lower housing part, and an upper housing part. At least one of the lower and upper housing parts is configured to include on an outside thereof an externally accessible cable accommodating groove.

An electronic module (1) includes a first electronic submodule (2) and at least one further electronic submodule (3, 4). The first electronic submodule (2) and the at least one further electronic submodule (3, 4) are electrically conductively connected to each other with an electrical conductor (5, 6), which is reversibly deformable, at least in sections. The first electronic submodule (2), the at least one further electronic submodule (3, 4), and the electrical conductor (5, 6) are encased in a fluid-tight manner with a casing (15), which is reversibly deformable, at least in sections. An actuator device includes at least one mechanical module and the electronic module (1). A method for manufacturing such an actuator device is also provided.

A shift device includes: a shift switching member including valley portions corresponding to a shift position; and an actuator driving the shift switching member. The actuator includes a motor that includes a shaft, a control board that controls the motor, a driving force transmission mechanism that is connected to the shaft, and transmits a driving force to an output shaft from the motor, a housing and an outer lid that form a housing space housing the motor, the control board, and the driving force transmission mechanism, the outer lid covering an opening of the housing, and an inner lid that divides the housing space into a first space housing the motor and the control board, and a second space housing the driving force transmission mechanism, and is housed in the housing space, and the inner lid covers the entire control board with respect to the driving force transmission mechanism.
