Fetrotech Tool EDC16C32 S1 and S2 Pinout Error Solution

Problem:

I tried to read Edc16c32 Mercedes w245 180cdi but Fetrotech tool software shows error s1 and s2 pinout error. Any solution

Solution:

The error means it not going into service mode, check the other connections and depending on brand of c32 MERCEDES/SMART EDC16C32 have 2 different pinout options.
If your pinout not working, try another option.
