It has turned out to be a good Thanksgiving for me - after nearly a year, my wife's crossfire has started again.The issue turned out to be a splice (S124) that went bad in the CAN bus circuit. That spice is located under the brake booster in the engine compartment. I tried to get to it, but the only way I could see how was by removing the brake booster. I didn't want to do that, so I cut the splices S116 and S117 which are below and to the left of steering wheel, remove the broken line from the splice, spliced a new wire in, and ran the wire to the SLA CAN wires. I put the minimum back together so I could test it first. Started on the first try. Hurrah. Now I have to put the interior back together and dress all of the harness that I unwrapped.
Some Details: The CAN bus has 120 ohm terminating resistors located in the SKREEM and the PCM. Since my SKREEM was isolated from the PCM, I would read 120 ohms instead of 60 ohms when I would probe between the white and green CAN bus wires. One side note, the minimum things that need to be plugged in to start the car was the SKREEM, the IC, the SLA, the TMU, the CAB, and the PCM. My steering wheel airbag was not installed, neither were my radio, and the center console switch
Great detective work, I'm happy that you got it figured out!
