Also, bear in mind that there are THREE lamps in the third brake light ass'y. If the middle one burns out, then it appears to be functioning just fine, but that will trip the VIC when you hit the brakes.
Also, if you don't have the specific (2057 from memory, please double check) bulbs in the running lights and brake lights, THAT will trip the VIC as well. Pull the bulbs, verify the part numbers against the manual, and replace them if they differ. Bulbs are cheap...you can always keep the ones you have for spares if you're in doubt.
