It is a convertible or drop top, whatever you call it. Any spooky issues like this, the first point of call, should be to verify if there are any control units residing in an area where water ingress is possible. Issues like these, would be 99% short to ground or ground issues. Diagnostics, visual, then pull and push diagnostics.
Why these europeans (presumably "smart"), do not label their wires on the schematic with colors, like dumb Kia or Ugo vehicles do? Mind U, I ain't no talking about this pardicular dia-Gramm, but many Mercedes Beemer diagrams I encountered. I had to call Identifix hotlines to guide me.
Its the type of diagram they use..common german layout...nowhere near as bad as french cars...or pre 1980s ford diagrams that seem to be handdrawn and require a microscope to see and decipher..😂😂😂
I ain't no gettin' the part why you bother tinkering with damaged board. Usu-Ally in Auto-Motive Indu-Stry we just swap bad part for goode-One. And pass the cost to Da Custo-Mer. Parts da cheap. Labor - no cheap. Unless, of course, the replacement parts are not available for some reason, but that happens super-rarely. I a-member Professor Ivan (Pine Hollow Auto) did not have a part for some strange and super-rare Chrysler or Ford truck 'cause Da Custo-Mer ain't no wanna pay for replacement module from Ford that cost thousand(s) of doll-llars (but da truck itself was worth only couple thousands of dollars). He just installed custom push button instead of the module.
This one was just an attempt to see if I could do it to begin with as I am still learning board work. So, I had nothing to lose while trying. Secondly it did have something to do with time constraint, it was going to take some time to even get a used one. I do agree with you, I would usually replace with a known good, but this time I was able to fix the original.
@@DTEAuto If you ever want to ask anything about "board work", then Automotive Diagnostics and Programming (Jake) is a real Programmer. He can probably give answers to "board work". He just wrote a program, in Python, in his latest video. Dude is a programmer. And I know from my own university experience, that if I can program, then I can do board work, too (cause I can).
I wasn't really in "need" of "asking" anything about board work, I clearly mapped out the circuits, figured out the issue, rectified it with physical repair of the components and got it working. There was no need of any type of programming here in this case. I'm well aware of Jake and what he does. Him and I have met and spoken in person at training events.
