Malfunction Indicator Lamp
The Malfunction Indicator Lamp (MIL) alerts the driver that the Powertrain Control Module (PCM) has detected an OBD II emission-related component or system fault. When this type of malfunction occurs, an OBD II Diagnostic Trouble Code (DTC) will be set by the PCM. The MIL is located on the instrument cluster and is labeled CHECK ENGINE, SERVICE ENGINE SOON, or is identified with an ISO standard engine symbol (i.e., a picture of an engine).
Each time the ignition switch is turned to the "on" position, the MIL indicator is illuminated for about 3 seconds (which is a function of the PCM).
To check if the Readiness Codes are set to complete, turn the ignition switch "on", but do not start the engine. The MIL will come "on" for 15-20 seconds. If it then goes "off", the Readiness Codes are set to complete, If it flashes five times, one or more of the Readiness Codes are not set to complete. To set Readiness Codes from incomplete to complete, perform the drive cycle procedure for the appropriate code.
