The PCM (Powertrain Control Module) constantly looks at the information from various sensors and other
inputs and controls systems that affect vehicle performance and emissions. The PCM also performs
diagnostic tests on various parts of the system. The PCM can recognize operational problems and alert the
driver via the malfunction indicator lamp (MIL). When the PCM detects a malfunction, the PCM stores a
diagnostic trouble code (DTC). The problem area is identified by the particular DTC that is set. The control
module supplies a buffered voltage to various sensors and switches. The input and output devices in the
PCM include analog to digital converters, signal buffers, counters, and output drivers. The output drivers are
electronic switches which complete a ground or voltage circuit when turned on. Most PCM controlled
components are operated via output drivers. The PCM monitors these driver circuits for proper operation
and, in most cases, can set a DTC corresponding to the controlled device if a problem is detected.
