98 ML320 w/ ETS light on

Hello all,

Today all of a sudden the ETS light came on and of course cruise control doesn't work. I checked and the brake lights are working, so its possibly not the brake light switch. Any other things to look out for?

Thanks in advance

Also, its been about 30K since my last brake change, so its starting to feel like I might need to get new pads. Would that be a sign to cause the ETS light to go on?

most likely stop lamp switch ( i know even though your brake lamps work). The switch is cheap and easy to replace.

I had the very same symptoms,brake switch fixed it. It was about 9.00 from a MB dealer. "AZINN" led me to a how to fix page. check back a few months and it will tell you how, really easy fix.

Local auto parts did not work.

Went got one at BAP/GEON, $15. plus tax. Installed it in the parking lot and it works fine.
