C2 8 Transmission Controls U1 U2 2 3 Location of the Data Link Connector DLC The DLC Data Link Connector or Diagnostic Link Connector is the standardized 16 cavity connector where diagnostic scan tools interface with the vehicle s on board computer The DLC is usually located 12 inches from the center of the instrument panel dash under or around the driver s side for most vehicles If Data Link Connector is not located under dashboard a label should be there telling location For some Asian and European vehicles the DLC is located behind the ashtray and the ashtray must be removed to access the connector If the DLC cannot be found refer to the vehicle s service manual for the location Ge 2 4 OBD II Readiness Monitors An important part of a vehicle s OBD II system is the Readiness Monitors which are indicators used to find out if all of the emissions components have been evaluated by the OBD II system They are running periodic tests on specific systems and components to ensure that they are performing within allowable limits Currently there are eleven OBD II Readiness Monitors or I M Monitors defined by the U S Environmental Protection Agency EPA Not all monitors are supported by all vehicles and the exact number of monitors in any vehicle depends on the motor vehicle manufacturer s emissions control strategy Continuous Monitors Some of the vehicle components or systems are continuously tested by th

If the MIL illuminates with a steady light it indicates that a problem has been detected and the vehicle should be serviced as soon as possible Under certain conditions the dashboard light will blink or flash This indicates a severe problem and flashing is intended to discourage vehicle operation The vehicle onboard diagnostic system can not turn the MIL off until the necessary repairs are completed or the condition no longer exists DTC Diagnostic Trouble Codes DTC that identify which section of the emission control system has malfunctioned Enabling Criteria Also termed Enabling Conditions They are the vehicle specific events or conditions that must occur within the engine before the various monitors will set or run Some monitors require the vehicle to follow a prescribed drive cycle routine as part of the enabling criteria Drive cycles vary among vehicles and for each monitor in any particular vehicle OBD II Drive Cycle A specific mode of vehicle operation that provides conditions required to set all the readiness monitors applicable to the vehicle to the ready condition The purpose of completing an OBD II drive cycle is to force the vehicle to run its onboard diagnostics Some form of a drive cycle needs to be performed after DTCs have been erased from the PCM s memory or after the battery has been disconnected Running through a vehicle s complete drive cycle will set the readiness monitors so that fu
