Hey Pros,
I've been trying to fix the ABS ESP and ETS light on issue on my ML32o (years 2000) by following the solutions from this Support Forum. I have done the following: wheel speed sensor check and cleaning, battery voltage check, brake fluid repalcement, ABS control module diagnostic, ABS and ESP ETX relay replacement and brack switch replacement. So far none of these could make the ABS ESP and ETS light to turn off. I wonder if these warning lights need to be reset somehow if one of the above issue could have resolved the issue. If so, how to reset the warning.

Thanks in advance for your advice,
BR/PY
