Complete cable for YAMAHA brand serial diagnosis. The cable is made up of six connectors: one 4-way (connector for models with CAN protocol diagnosis), the second and the third 3-way (male and female connectors for models that request double or individual connection), the fourth and fifth connector with strut (male and female struts for models that request double or single connection) and the sixth 2-way connector (power). To carry out a correct diagnosis, it is necessary to carefully follow the instructions of the diagnostic instrument. If requested, connect the clamps to the vehicle battery. NOTES: the cable replaces, as a sole solution, all previously produced cables (3151/AP40, 3151/AP47, 3151/AP49).
