The Jaltest JDC601A connects the proprietary 3-pin diagnostic connector of Yamaha personal watercraft with the 16-pin OBD2 input of your Jaltest diagnostic cable. On the engine side is a grey rectangular waterproof plug with three chambers in a black strain relief. The cable is 28 to 30 cm long and the connector is located in the engine compartment.
With the cable connected, the Jaltest software reaches the ECM EFI, the engine management unit, and the RiDE SCU, the control unit for the braking and reverse system. On the engine management unit you can read fault codes and measured values, activate components and set parameters; on the RiDE SCU you get fault codes, calibration and live data. The cable works with the Jaltest Link V8.1 and V9 and falls under Jaltest Marine.
