It sounds like the BCM might have gone out. but to be sure lets check the fuses on the BCM # 4, 6, 1, 3, 7 and the IPC fuse as well. Here is a guide to help you test for power at the fuse and the fuse locations as well. Also I have included the running light wiring diagrams so you can see how the system works and the BCM location. If the fuses are good I would get a new or rebuilt BCM and have it programmed which will cost about $130.00 at a shop. Check the diagrams below and get back to me.
Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.
