ABS problem and error codes.

[JudgeM]

I get ABS light come up sometime. I would say maybe 2 times a month. Seems to randomly come up. I can't think of any specific action I did to cause them. If I restart the car, the ABS light goes away.

So one day I was driving with my Techstream stuff. The light came on again. I pulled over and ran a scan. This is what I got:

C1241, C1249

Any ideas how to fix this ?
