A bracket for supporting a vehicle control module, such as a powertrain control module, is disclosed. The bracket includes a body having a base wall, nodes or support posts, and side walls. The base wall includes back and module-receiving sides. An array of intersecting ribs is formed on the back side while at least one array of honeycomb segments is formed on the module-receiving side. At least one of the honeycomb segments includes a top layer. Substrate attachment arms extend outwardly from the side walls. Support posts extend from the back side of the base wall. Three intersecting ribs are provided, generally forming a triangle. One or more additional ribs may be provided. The intersecting ribs are hollow. The individual ribs function as structural beams that connect to and thus work in conjunction with the nodes or support posts and the honeycomb to provide optimum stiffness to the bracket.
