Requested Torque Signal Circuit Malfunction c1277?

So what does this trouble code mean? My ABS and traction control lights come on every now and then. I took my car in for a state inspection and asked them to pull trouble codes so I could find out what was wrong with my ABS system. All they pulled was a Code c1277 requested torque signal malfunction. The ABS and traction control lights only come on once in a blue moon. I cleaned all the chassis grounds that I could find. I cleaned all the ABS fusses (contacts were dirty) and replaced the ABS relay. I the ABS light and Traction control lights have not come on since. Both systems work great. But what does this code mean? Its for a 1996 Pontiac Bonneville SSEI.
