Mercedes W203 2007 no power on ESL cable

[kacperor]

I changed EIS, wanted to plug in esl emulator which was working ok and suddenly I have no 12V to plug emulator.

Checked battery and fuses ofcourse

[mercis]

open eis and clean copper contakt

Same thing happens on 2 different EIS. Its not eis fault. What else is possibile?

[pawl]

hi to me it looks like f31 fuse, dashboard location

[kacperor]

I double checked it even changed, does not help

RDVT +12V from 31 fuse ,
RDGN +12V from eis C connector 4 pin ( eis must be connected )

[kacperor]

Can u tell me how to do it (im still learning)

[kacperor]

I also checked there is 12V in EIS - its like eis is not giving power to esl

[kacperor]

There is 12V comming with blue plug into EIS but in ESL plug there is only 0,3V

31 fuse is ok

[kacperor]

Bump, any help?
