Getting Started

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 SAE (J1962). The DLC should be located under

the dashboard on the driver 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

2 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
