I've searched around on the cause of this failure but it doesn't seem to be any conclusive reason why a car would get these problems.

I have a 2006 C2S and the PSM, ABS, CEL warnings come on when you start the car. I had it plugged into durametrics and it says it doesn't a signal from the rear right wheel speed sensor. The sensor was replaced but still haven't the same issue.

It gave me an error relating to this number 99761810906

I have a Brake Light switch on its way which I'm going to try. Battery voltage is 12.3v when the car is off so it seems fine.

Any other possibilities other than the PSM/ABS controller? Thats my last option seeing how expensive it is. Does anyone have the part number for those?

Thanks!

Replaced the brake light switch and its still the same problem. There was a PASM error before but that seems to have cleared after replacing the abs speed sensor.

Could be the ABS reluctor ring on the hub.

I had a similar problem with my MINI. The reluctor ring had been scuffed by a pebble and the sensor wasn't able to read the magnets in them. Replaced it, and I was good to go.
