Ronnie......Thats a Big 10-4. Glad you split this ECM/BCM/CRT Code stuff from my ABS issues. I will finish up with the ABS thread (hopefully with the system back to normal again), and then come back to this ECM/BCM/CRT thread.
I will review the Onboard Diagnostics Booklet as I have extra time (I will check the huge shop manual and see if that info. is also there).
