This code is telling you one of a few modules is not communicating correctly they list is as follow's, PCM, safety restraint control module, ABS module, instrument cluster, CAN not communicating with PCM correctly or the GEM not doing its job. When the light comes on is there anything else that won't work besides the trac control? It sounds like the ABS control module is not working right I have seen this problem. I would check fuse number 63 and 32 which go to the BCM
Here is guide and fuse locations.
Check out the diagrams (Below). Please let us know what you find.
