Complete cable for diagnosis and reprogramming of SWM Euro 4 vehicles. The cable is made up of two connectors: one 6-way (line) and one 2-way (power). To carry out a correct diagnosis/reprogramming it is necessary to connect both connectors to the corresponding sockets located in the vehicle. These shots are not always located next to each other. Normally, the power socket, fitted with a cover, is located near the battery or between the headlight and the dashboard. NOTE1: Some series of models are born without the 2-way socket for power. In this case, to power the instrument and guarantee diagnosis/reprogramming, it is necessary to connect cable 3151/AP51, cable 3151/AP55 and the clamps of the latter to the vehicle battery to the 2-way connector. It is advisable to always check the connection instructions present in the software. NOTE2: The cable does not manage the diagnosis of the ABS system for which it is necessary to use cable 3151/AP07 and strut 7.
