Volvo J1939 (OBD2 Style Male) to J1939 (Male) Adapter

As of 2013, Volvo has a new OBD2 Style diagnostic connector for a Volvo chassis with a Volvo engine. Volvo still plans on keeping the standard J1939 9-pin Deutsch connector for a Volvo chassis with a Cummins engine. The new interface has two separate CAN channels with ISO15765 on CAN channel 1 and J1939 on CAN channel 2. It will also have J1708 in the connector as well.

This adapter allows the use of a standard J1939 tester to connect to the new connecter style. It hooks into the Channel 2 standard J1939. It also allows the use of a standard GPS unit or other J1939 heavy equipment accessory with the new Volvo connetor style connector.
