Data Link Connector (DLC)
The data link connector (DLC) allows the Scan Tool to communicate
with the vehicle’s computer(s). Before OBD II, manufacturers used
different DLC’s to communicate with the vehicle. use the proper DLC
adapter cable to connect the Scan Tool to the vehicle. Also, the vehicle’s
DLC may be found in several different places and have many different
configurations. The following describes the DLCs used by Ford, GM
and Chrysler. The DLC location and types for domestic vehicles can be
looked up in the charts in Appendix B - Data Link Connectors.
OBD II (J1962)
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.
Because the OBD II J1962 connector has power and ground, you only
need a single cable connection to the tool for both power and tool
communications. Attach the OBD II adapter cable to the extender cable,
(both supplied with the tool) to connect the tool. Certain pins in the
connector are reserved.
