I acquired my '98 ML320 about 6 years ago. The ABS lamp lit sometime later, and the local MB dealer had "never seen this before", so used it sans ABS for years. I stumbled upon Jim's post, and being an electronics tech, thought I would check it out. The weather was 80f when I resoldered the pc board (2 wire connector). Two days later, even though the ABS light was off, I ran over some icy road to see if it REALLY worked. It did!

Thanks Jim!
