If the Bulb burns out, the ABS still works!
I needed a new ABS sensor on a rear wheel. When the car reached 60 mph, the light came on and the ABS was deactivated. The sensors read car speed and check it with the cars speedometer. If there is a descrepancy, it will defaul and deactivate.
My car behaves as yours does. You can feel the ABS with your foot when it activates, but no light comes on. The light only comes on for a second or so when you start the car. I assume it's a check light. I've read that if the bulb is burnt out, the ABS system detects this and will not activate.
When i was an intern at Bosch working in the ABS dept, the overview on day one explained that the ABS dash light flashes when the system is activating so people know why the pedal is shaking. Well, I've been under the impression that The anti-locks were kicking in with the snow here, but nothing on the dash lights up. Whem I start the car, the ABS light does go on, so it's not burnt out. Am I right in assuming that it is just a system check light?
