You could go old school with a clamp type meter
At the computer seperate all the wires and turn the key on not start and measure the amps of every wire ...one by one..The one wire with the highest amps is the circuit that has the short... Takes time but no fancy equipment needed.. Then trace that circuit for the short... 10 miles of spaghetti lol

Lol, I been at this with no car since October, 10 miles of spaghetti dont sound that bad right now, especially if I can find this dang short and fix it. 🤦‍♀️🤣

I have the wiring diagrams and will be tracing wires tomorrow! I'm so grateful for everyone's help and advice on this. I cant give up now, and with this information i hope to solve this issue soon! Have a great night everyone. Hopefully I'll have a good update soon! 🤞🤞

I'm hoping Chevrolet or gm will email me back with that information. I have tried to find a mechanic around me, I thought I found 1 and he said since I didnt have a code visible that he couldn't do the computer part of the car and just told me what the outside needed, and still charges me $100. I deleted the camshaft sensor code after I replaced it and the harness, hoping that was gonna fix it. So since he didng see that code then, he said he couldn't pull codes with his computer. Hopefully I'll get this diagram soon and go from there. Or find someone that knows what there doing that can come to my house.

There are stored codes that a good quality scope can pull up providing they haven't been erased previously. A savvy technician should know that. I would reach out to the Scanner Danner website. You can join and present your issues on the website. There are some really good technicians that prescribe to the website that can help guide you along. Sounds like you either have a module that is dead or a sensor shorting the data line. CAN buss. You can take a multimeter and check the 5 vdc at all the sensor connectors. They should all have a 5 vdc. If not, the sensor is shorted. Disconnect the connector. If the 5 vdc returns, you have identified the problem sensor. Another way is to disconnect every sensor and see if the problem disappears. That will tell you if you have a bad sensor. Thats a lot of work but may be the best route. If all the sensors are good, then its either a bad module or a shorted wire somewhere. Also, as has been mentioned, be sure every connector to all the modules, especially the ABS/Antilock brake module is completely connected. That connector has to be completely seated. If it isn't, it can cause some weird issues.

Noted! And will do that this evening. I'm actually sitting in a emergency room right now, and it rained today so I didnt get a chance to look at it. But I'll definitely post on there website and get back to working on it tomorrow. Thank you so much for the info. It might have took me 5 months but if it's the last thing I do I'm gonna figure this car situation out! Lol
Thanks again I truly appreciate the info!

"threw this code about 2 weeks ago."
It ran fine untill about 2 weeks ago when you got the U0100 code?
