VVDI MB Failed to Read W230 2003 Password Solution

 Problem:

I got a problem reading Mercedes W230 2003 EIS password with xhorse vvdi mb tool. I have the original key in hand and need to add a spare key. Try both IR and OBD failed.

Solution:

Need to remove EIS and read with vvdi mb or vvdi prog.

 

Remove EIS and read with vvdi mb and EIS/EZS test adapter following the wiring diagram below

FYI: Check more Benz EZS/EIS bench pinouts here 

 

Or read EIS data with VVDI Prog
