    Good morning all. I hope that the past holiday served you all well and the virus isn't part of your life. I have a 2010 SHO that Forscan can't seem to communicate with the BCM. Found wires snatched apart by something that decided that the car was better than outdoors and repaired them all. Don't know which way to go now and could really use some guidance. My ears and eyes are open.

    Ouch, how bad is it? Might be better to just get a donor harness to swap.

    Not too bad. Just tedious. All broken wires were accessible through the back seat. They nested on both sides. I just keep getting the U0140 code.

    What module(s) are losing communication to the bcm? Does the car start/run? Are there any warning lights?

    I'm open to a PM if necessary. I tried to run a test on the following modules with FORscan and the test failed: PCM, FCIM, HVAC, ACM. I have no power to the a/c controls and the cluster lights are always on, thus draining the battery. I have codes on the modules also. Three of them are "U" codes. Warning lights are DTC light, TPMS, and parking brake.

    What are the specific dtcs you have? What is a dtc light? Do you mean a check engine or a wrench light?

    I'm assuming the car starts and runs so there is power, ground and communication to the pcm.

    The cluster lights staying on with the ignition off can you describe that further? Do you have any warning chimes when you open or close the door?

    Sorry. Fell asleep. Traction control, is the DTC light. There is a chime for warnings like door ajar when the doors are closed, trunk ajar when the trunk is closed. The lights surrounding the gauges (the little markers) are continuously on. Codes are as follows:
