Data Link Connector (DLC)
The data link connector (DLC) allows the Scan Tool to communicate
with the vehicle’s computer(s).
Beginning in 1996, vehicles sold in the United States use the J1962
(OBD II) DLC, a term taken from a physical and electrical specification
number assigned by the SAE (J1962). The DLC should be located
under the dashboard on the driver’s side of the vehicle. If the DLC is not
located under the dashboard as stated, a decal describing its location
should be attached to the dashboard in the area the DLC should have
been located. For more information on OBD II connectors, go to
