Sounds great, I greatly appreciate your help with this. I just checked the grounds again that South Main Auto showed on his video. Both of them I checked looked good. (Passanger side head to fire wall, and one behind front right wheel) I also checked voltage drop between negative post and frame and don't have any voltage drop. I will check the connection to the power steering control module. If that looks okay then ill throw a rack on it to see if it solves it. Thanks again for your help

Hi, I am having issues with a 2021 Silverado 1500 LT 5.3L. The issues I have are Service Power Steering Message, Service ESC Message, No Cruse Control, No rear backup guide lines (even when guide lines are turned on). Error Codes: C1512 Control Module Power Circuit Low Voltage C0051 Steering Wheel Angle Sensor Signal / Clock Spring U0415 Invalid Data Received from Electronic Brake Control Module I purchased a new clock spring assuming the steering wheel angle sensor was integrated into it, but I am no longer certain that assumption is correct. I have searched extensively for documentation identifying the exact location of the steering wheel angle sensor on this model truck. On earlier versions it was a standalone sensor. I contacted the dealership, but they were unsure of its location and suggested it may be integrated into the steering column assembly, which I also have not been able to confirm. I have also checked the ground strap that is located behind the passenger wheel and it looks okay. I am assuming the issue is related to either the clock spring or angle sensor (if I can find out where its actually located). From what I have read the cruise control is disabled when you get ESC error, and I assume the no rear backup guide lines (even when the guidelines are turned on) is related to the truck not able to read what angle the steering wheel is at. Any guidance on this would be greatly appreciated. Thank you
