Hi,
Here I have a bit of a complicated issue which I don't understand and I'm completely lost.
I have bought this E350 W212 convertible and had an intermittent ESP, Tyre pressure Inoperative...
I have scanned with Isoft Vo 3 and showed me the brake light switch intermittent or implausible signal.
While fidling around to fit a seat mat modulator to override the SRS light i have discovered that fuse 21 was not in and could not make the emulator to work. I have replaced the fuse and purchased a brake pedal switch.
After replacement the fault keeps coming back to find another fault to circuit 54 with inplausabale signal from rear SAM.
While testing for data in the rear I have found light brake and the voltage varies from 9v to 10.. when I press the brake without the engine on and as soon as i start the engine the voltage increases. The other switches and when i look at brake light switch in the esp module it does show 12.6 V and most of the switches are the same.
I have been measuring fuses for that 10v low voltage and can't find one.
Also I have been pulling fuses out to see which one controls the brake lights and no fuse so far has stopped them???
