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