3. The Vehicle connection  LAUNCH X431 Diagun IV:

The method used to connect the LANUCH connector to a vehicle's DLC depends on the vehicle's configuration as follows:

  • 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.

For non-OBDII vehicle,proceed as follows:

1. Locate vehicle's DLC socket.
