Hello all, I have a 2002 Mercedes e320 and while I was driving the other day it turned on suddenly. Anyways any idea what it can be? I checked the fuses all fuses look in good condition. Brake fluid is topped off too. What should I check next? Wheel sensors? How can I tell if it’s bad?
Check the wheel speed sensors. A broken wire, excess metal on the sensor, or even a bad tone ring can screw with the ABS system.
