diagnostic socket, please use the included VCI module. (For vehicles with
non-OBD II 16 PIN diagnostic socket, a non-16 PIN connector is required.)
4.3.2 DLC location
The DLC (Data Link Connector) is typically a standard 16-pin connector where
diagnostic tools interface with a vehicle’s on-board control modules. The DLC is
usually located 12 inches from the center of the instrument panel, under or
around the driver’s side for most vehicles. If DLC is not located under dashboard,
a label should be there telling location. For some Asian and European vehicles,
the DLC is located behind the ashtray and the ashtray must be removed to
access the connector. If the DLC cannot be found, refer to the vehicle’s service
manual.
