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 centre of the instrument panel (dash), under or
around the driver’s side for most vehicles. For some vehicles, the DLC
is located in the passenger foot-well and in others it may be behind the
ashtray. Refer to the vehicle’s service manual for the location if the DLC
cannot be found.
2.4 OBD II Readiness Monitors
An important part of a vehicle’s OBDII 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. Periodic
tests are run on specific systems and components to ensure that they
are performing within allowable limits.
