The ABS was woking fine until the snow storm we had. Now the servious soon light and the ABS light are coming on together at the same time, but only when the traction slips, it's also triggering the trac light.

We also just have the drivers side front hub assembly replaced at the dealers shop.

Anyone know what might be happening?

 

Sounds like a bad wheel speed sensor, or a bad connection at one of the sensors. Check the hub that was replaced to make sure the connector is seated properly, and that its free of corrosion.

 

Good advice from 2k2cse. Can't think of anything else to add.

 

go to auto zone and have them read the ck engine and abs codes. DON'T BUY ANYTHING! write them down and post them here.
