Data Link Connector
The Data Link Connector (DLC) is a standard 16-pin interface located under the
dashboard on the driver’s side of the passenger compartment. 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 where the DLC should have been located.
On some Asian and European vehicles the DLC is located behind the
“ashtray”, which must be removed to access it, or on the far left corner of the
dash. If the DLC cannot be found, consultthe vehicle’s service manual for the
location.
