2000 Cadillac DeVille Question: Traction control and ABS lights on dash?
Traction control and ABS systems share the same wheel speed sensors and its not uncommon to see one of them fail at the age of yor car. Need to have that sytem checked with a compatable scanner to retrive fault codes to go any further toward a diagnosis and repair. - milesauto

There are two schools of thought on this matter. First, the ABS module is located under the air cleaner and either the motor or the module, itself, are bad and will cause the lights (on the dash) to come on. Secondly, there may be a bad Relay, the #1 or the #3 relays, under the seat may be bad. I have yet to prove either of these solutions. I'll let you know. - Larry51
