I Have 2000 Cadillac Deville & 3 Weeks ago my ABS Traction Control & Brakes warning light came on has anyone had this problem before? What do i need to check to fix this?[sm=smiley20.gif]

 

Check the wheel speed sensor wire harnesses at all 4 wheels. A chafed, loose, dirty speed sensor harness that goes just behind the caliper can cause this.

 

Thanks carnutill take a look at it. I pulled some codes from dashboard they are C1214 and C1248does this codes have to do with the speed sensor.[sm=helpout.gif]

 

Also an easy thing to check that could cause this is uneven tire pressures and tire tread thickness. if one tire is lower than the rest then its going to rotate at a different speed than the rest of the tires. causing the ABS/TC module to throw a traction control fault.

 

i'm sure this is too obvious .. but .. have you checked:
fluid level?
harness switch connector to the master cylinder?
