    Abstract: An automated method for diagnosing an EGHR having a coolant path, an exhaust path, a heat exchanger, and a valve. The coolant path passes through the heat exchanger and the valve selectively directs the exhaust path through the heat exchanger. The method includes monitoring an inlet temperature and an outlet temperature of the coolant path, determining an instantaneous coolant power from the monitored inlet temperature and outlet temperature, and integrating the instantaneous coolant power to determine a total energy recovered by the coolant path. The method monitors an instantaneous exhaust power, determines an instantaneous available EGHR power from the instantaneous exhaust power, and integrates the instantaneous available EGHR power to determine a nominal EGHR energy. A differential is calculated between the nominal EGHR energy and the total energy recovered by the coolant path. If the calculated differential is greater than an allowable tolerance, an EGHR error signal is sent.

    Abstract: A multi-position actuator includes a solenoid selectively energized to extend a rod. The actuator also includes a push-lever pivotably mounted to the rod and a crank-arm rotatably mounted on a first axis. The crank-arm includes multiple engagement elements arranged on a diameter centered relative to the first axis, and also includes a projection. The push-lever engages one of the engagement elements to rotate the crank-arm about the first axis in a forward direction when the solenoid is energized. The actuator additionally includes a pivoting locking-lever that blocks rotation of the crank-arm in forward direction and a one-way-clutch that blocks rotation of the crank-arm in reverse direction when the solenoid is de-energized. Furthermore, the actuator includes a slider-box lever having first and second slots. The projection slidably engages the first slot. The second slot is engaged with and operates an external device when rotation of the crank-arm swings the slider-box lever.

    Abstract: An electronics housing for a high voltage system of a vehicle defines an interior region, and includes a connection header wall having a window. An optical proximity sensor is disposed within the interior region of the electronics housing, adjacent the window. A cover is removably attached to the electronics housing adjacent an exterior surface of the connection header wall. The cover is disposed over the window. The optical proximity sensor is operable to sense the presence of the cover through the window when the cover is attached to the electronics housing.
