Data Link Connector: Description and Operation
DLC
DATA LINK CONNECTOR
The provision for communicating from vehicle to scanner is the Data Link Connector (DLC). It is usually located under the instrument panel and
is sometimes covered by a plastic cover labeled "DIAGNOSTIC CONNECTOR." It is used in the assembly plant to receive information in
checking that the engine is operating properly before it leaves the plant. The connector can also be used by the service technician to identify
Powertrain Control Module (PCM) stored trouble codes.
NOTE: There are two different types of DLC connectors, a 12 terminal and a 16 terminal. ONLY the 12 terminal connector which is equipped
with a terminal "B" will flash DTC codes through the Service Engine Soon / Malfunction Indicator Lamp (MIL).
