I have a 190e 2.6, 1989, ABS light is on and will not go out, I checked the overload protection relay fuses and they are OK, I did put a new one, but still the ABS light is Oon during engin running, I have hard time to start the first time but after a while of running engine, it is fine, I thought it might be due to overload protection relay, but I do not know how to chech it? any help is appreciated.
Thanks

That's OVERVOLTAGE Protection Relay.

The ABS sensors on the front wheels may be 'shorted' out with metal filings. Pull them out and clean them, as well as the reluctor wheels.
