Super 16 Connector
As you are no doubt aware, the Launch X431 system has a number
of 16-pin OBD II-style plugs; OBD-16C and CAN 2 are by far the most
popular.
Although your X431 will tell you which plug to use it will only
do this after you have connected to the car potentially wasting time.
The NEW Launch Super 16 connector avoids this by covering the functions of the SMART
OBD, OBD-16C, CANBUS II plugs as well as the BMW-16 and TOYOTA-16
plugs.
Additionally the super 16 connector can read both the single and
double wired CAN bus allowing additional coverage for new Opel, Saab and GM
vehicles, especially for the SRS system and some BODY control
systems.
Also the CITROEN/PEUGEOT converter required for use with the CAN
2 plug
