OBD II compliant.
3.5 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 DLCs 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 scan tool supports OBD I DLCs used by Ford, GM, Chrysler, and Toyota.

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. For more information on OBD II connectors, go to http:// www.obdclearinghouse.com/oemdb.
Because the OBD II J1962 connector has power and ground, you only need a single cable connection to the tool for both power and vehicle communications. Attach the OBD II adapter cable (7-0138) to the extender cable
(7-0137) (both supplied with the scan tool), to connect the tool. Certain pins in the connector are reserved.
Ford (OBD I)
Ford used three types of DLCs with their OBD I systems.
After vehicle selection, the scan tool will indicate which cable is required.
IMPORTANT
Use the included cigarette lighter cable
(7-0135) to provide power to the scan tool for all systems.
EEC-IV
The EEC-IV DLC is a large 6-sided connector with a pigtail connector. The EEC-IV cable adapter (7-0140) is included with the scan tool.

MECS vehicles (1988 –1995) use either a 6-pin (with
pigtail) or a 17-pin DLC. Use the MECS 6-pin adapter cable kit (7-0143) for both configurations. The MECS adapter cable kit includes jumper wires to connect to the MECS 17-pin DLC. The MECS adapter cable kit is not
