traction shutting down

I have a 2000 Chev venture- The traction system keeps shutting down and shutting down the ABS with it. I have been to 3 different mechanics. One reset traction mode? Another change the right front wheel hub and the last did nothing.. any one with any ideas

Any other electrical "symptoms"? Are your turn signals all working properly? Try operating all of the lights while someone is watching (turn signals, hazard lights, brake lights, reverse lights, etc.) Burned out contacts in the wiring harness connector plugs to the rear tailamp assemblies will disable the ABS and TCS system and cause those dash lights to come on.
