5.1.3 Vehicle Connection

The method used to connect the diagnostic connector to a vehicle's
DLC depends on the vehicle's configuration as follows:
• A vehicle equipped with an OBD II management system supplies
both communication and 12V power through a standardized DLC.
• A vehicle not equipped with an OBD II management system
supplies communication through a DLC connection, and in some
cases supplies 12V power through the cigarette lighter receptacle
or a connection to the vehicle battery.
Follow the steps mentioned below to connect OBD II vehicle:
1. Locate vehicle's DLC socket.
