How to build EIS/ELV NEC adapter for VVDI MB Tool


Have EIS/ELV cable tester for your vvdi mb tool? Think it expensive? You can make EIS/ELV NEC adapter by yourself and save a lot.


For Mercedes W204 W212 W221 W164 W166, it’s necessary to have this adapter to use with the EIS ELV maintenance, Mercedes key programming and key detection.


Here are some diagrams for reference.

w203 / vito w639 with mcu HC908 inside




















w203 with mcu hc912 inside




















W204 / W207 / W212 with NEC inside

















W210 / W208 / W202 with HC705 iside

















W211 / W219 / W209 with HC912 inside



















W220 / W215 / R230 with HC705 inside



















But if you are not interested in building one on your own and want to spend a little bit more money to get a working EIS/ELV Tester, then this is a site that has been confirmed working by some of our mb friends: xhorse elv adapter,elv adapter, eis/elv test cable.

… I wouldn’t recommend other sites, although they may work, problem is that they have not been confirmed working yet. Functions of EIS/ELV adapter at mbstartool has been tested for years (many discussion in forums).
