97 e-36 abs-asc+t

[TEXAS RED]

Both of the above lights are on at the dash. A BMW Racing tech I met said it was a wheel speed sensor, surely. I have cleaned all four bit he said they do go bad. Anyone know how to check them to see if they good or not? And if I replace a bad one will I have to re-set the computer or will the lights go out on there own after a bit? The ABS seems to be working fine. Thanks :Richard

My ABS light is on too along with the ASC-T, but my ASC-t is disconnected and the ABS line has a resistor in it to fool it into thinking it's still hooked up. The reason I mention that is could that plug have come loose that runs the actuator for the secondary throttle body? supposedly if you just pull that out and don't put in the resistor it messes with the ABS. Just a thought, BTW my ABS light just came on today, I'm hoping its a connection for the right front sensor because that's the only one that's been disconnected.
