Service Traction System Light comes on intermittently.

What is your question?

Hello, I just bought a 2002 Monte Carlo SS with about 156,000 miles. It has a few problems like stalling that we are working on. But another issue it has is that the Service Traction System light comes on intermittently. I thought maybe it was because it was set as on and not off but rather it is on or off the warning light still comes on. Any ideas about what to do with this? Thank you in advance for your time.
