ETS/BAS warnings & cruise control malfunction

[jenningsm62]

Have several warning messages on my 1998 E320 4 matic. "BAS", "ETS", messages on multi function indicator, and amber light ETS/BAS in lower left dash display. Cruise control stopped working at the same these came on. Read some threads about brake pedal switch and also wheel speed sensors causing these warnings. Anybody know where to look for these and how to replace? Could this be as simple as a blown fuse? I hope it's as easy fix, hoping to cut down the learning curve. Input anyone??

The brake switch should be just above the brake pedal. I forget how it's changed, but I remember it involves a 1/4 twist to remove the old one.

if you are getting error messages on the hud most likely you have codes, get the codes

In my mom's 1999 E430, I seem to recall a low voltage problem can cause those kind of problems.
