DATA LINK CONNECTOR (DLC) / MIL
DATA LINK CONNECTOR (DLC)
Toyota vehicles are equipped with special Test Connectors that make
it possible to connect specialized testing equipment that communi-
cates with the vehicle's onboard computer. This Tool is designed for
use with two types of Toyota DLC connectors; DLC Number 1 and DLC
Number 2, as described below.
The Tool's Toyota Connector Cable Adaptor is designed to
match the vehicle's DLC. Make sure the adaptor mates prop-
erly before applying any force when making the connection.
Applying force to the connector when not mated properly
may cause damage to the connectors.
