The Jaltest JDC661M is the key programming adapter for the 2-pin connector on Yamaha jet skis; the adapter bridges that connector to the IMMO side of the Jaltest equipment. The 2-pin connector is located in the jet ski hull, and the compact adapter design connects directly to it.
Using this connection, the Jaltest equipment programs the jet ski's keys. Key programming and diagnostics are separate functions on Yamaha: To read the control units ECM EFI and RiDE SCU, use the Yamaha diagnostic cable (JDC601A), which connects to the 16-pin OBD2 side. The adapter falls under Jaltest Marine.
