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 code readers 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.

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 in every 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 the vehicle's OBD II system, while others are tested only
under specific vehicle operating conditions. The continuously monitored
components listed below are always ready:
