Hi, a couple of months ago my car's ABS motor started running continuously, even when the engine was off. This caused the battery to die many times, so we used to disconnect the negative battery cable when the car was parked. Later, I removed the ABS motor fuse, which solved the battery problem, but now the brake warning light doesn't turn off and the odometer/kilometer readings are not working. PS: The dynamo pulley ball bearing was broken. I fixed it yesterday.

So, this happens when the ABS pump motor control relay sticks on which is part of the ABS control module so it will need to be replaced, unless you can open it up and change out the relay. Here is the location, I would try to get a used unit from eBay, I have had great luck with there stuff. Check out the images (below). Please let us know what happens.

So if that relay is replaced, the odometer and speedometer will start working again?

It might help the odometer reading but this would be for the ABS motor running, and the speedometer goes through the ABS module so that should fix that as well, let me know what happens please.
