Thanks, ***** ***** checked the ground connection and it seems OK. Do you have an electric diagram for this particular car model (e400 convertible) ?
Expert:  Lou P. master tech replied 4 months ago.

yes and no, our diagrams are broken up into functions and modules, so there are literally hundreds of different diagrams. the code that states the module is defective is proof the module needs replaced. the computer is smarter then us sometimes lol.

Customer: replied 4 months ago.
When the problem occurred, it was not only this module that displayed alerts but others as well: SOS inoperative, Lane keeping assist, SRS malfunction and sometimes Power Steering. I suspect an electrical problem affecting all these modules. What is your opinion ?
Expert:  Lou P. master tech replied 4 months ago.

well all the modules work together so when something like the traction module has an issue then yes you can see all kinds of faults from other systems. so you can have 1 module having an issue but 7 different warning lights on the dash if this makes sense. what kind of scan tool do you have?

Customer: replied 4 months ago.
It's what garages have; it looks like a military laptop. I have several pictures of the error messages.
Expert:  Lou P. master tech replied 4 months ago.

a lot of my customers buy from

www.mbstarshops.com

and ebay for icarsoft scanners.
