The Powertrain Control Module (PCM) monitors several different circuits of engine control system. If a problem is sensed with a monitored circuit, PCM will store a trouble code to aid technician in diagnosis of system. The Malfunction Indicator Light (MIL), also called the CHECK ENGINE light, or Diagnostic Readout Box (DRB) can be used to read trouble codes.
