This function allows user to read states or values of a variety of sensors, inputs/outputs and components. PCM can only recognize high and low states on switch circuits. PCM cannot differentiate between an open or short circuit or a defective switch. If DRB displays a change between INPUT HIGH and INPUT LOW, assume the entire switch circuit to PCM is functioning.
