W202 BAS ASR and ABS lights

[Swedish Benzdude]

My BAS-ASR and ABS lights have come on and of this last winter and in the spring-time they never went off. When the lights are on the ABS and ASR doesnt work. I have narrowed it down to the fault-code C1100. The code comes up again right after I’ve erased the code. I have replaced the sensor but the problem remains. Where do I go from here and can anyone supply a wiring diagram for the ABS-module? The car wont pass inspection unless the problem is fixed.

did you get it coded to the car

Welcome to the forum.
Just a few questions.
Which car are you having the issue with?
When does the fault light come on, before the car is moving or after?
Which sensor did you replace and what make?
I guess the first port of call is to investigate the ABS sensor and signals for each wheel.

As mentioned have an assistant read the wheel speed sensor readings whilst travelling at a constant speed.
Also check wheel bearing adjustment and the reluctors for rust/corrosion.
