All the ECM’s or PCM’s will generate some normal heat from the transistors, processors, or chips. If you are having failure from a problem, then there should be codes stored inside the module that may indicate the problem. You may feel the housing is warm or even hot on sections that have heatsinks. If you begin to experience more severe drivability concerns, I would have a certified technician inspect your electrical system to see what may be causing the modules to overheat.
