"Service High Voltage Charging System" Fix...
Thank you for your video. I have a 2012 Volt (190,000mi) and had the "Service High Voltage Charging System", DTC a few years ago and had purchased the VCX Nano that I reprogrammed the vehicle many times until I could get the bypass device to take care of the issue. I recently had a radiator changed out and the problem returned.
