A controller area network node comprises an internal high differential bus line and an internal low differential bus line. The present compounds may be useful in the treatment andor prevention of conditions mediated by Peroxisome Proliferator-Activated Receptors, in particular the PPAR\u03b4 subtype. If necessary, a power-actuated nut runner, mounted on the robotic manipulator or adjacent the mounting station, is used to tighten a nut over the valve stem. The phase-change memory device has a phase-change material layer which is changed from an amorphous state to a crystalline state by a current, and a heating layer composed of SiGe that contacts the lower surface of the phase-change material layer. An exemplary system includes a controller configured to control a urea injection system to perform a wash cycle in accordance with the exemplary method.
