3 Preparation & Connection

3.1 Preparation

1. Turn the ignition key on.
2. Locate the vehicle's DLC socket: The DLC (Data Link Connector) is
typically a standard 16-pin connector where diagnostic code readers
interface with the vehicle's on-board computer.
A. For Passenger Vehicles,
The DLC is usually located 12 inches from the center of the instrument
panel (dash), under or around the driver's side (See Fig. 3-1 for DLC
location). If Data Link Connector 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.
B. For Passenger Vehicles,
The DLC is usually located in driver's cab.
If the DLC cannot be found, refer to the vehicle's service manual for the
location.

3.2 Connections

The method used to connect the main cable to a vehicle's DLC depends on
the vehicle's configuration as follows:
A. OBD II Vehicle Connection: Plug one end of the main cable into the
vehicle's DLC, and the other end into the diagnostic socket of the e-VIN,
