The ABS warning light on my '01 Sentra has been acting funny recently.
It will come on pretty much every morning (for the last couple weeks) when I first start up the car. If I then turn off the car (just after starting it) and start it up again, the light is off every time. It also does not come on in the afternoon when I drive home from work. This pattern happened a while back, then disappeared for a while, but has now returned. Any thoughts on what the problem might be? The brakes seem to be working fine, although I haven't been in a situation where the ABS would have been tested.
