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.
2.4 OBD II Readiness Monitors
An important part of a vehicle's OBD II system are 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.
