Chevy Volt / Opel Ampera SHVCS DTC Clearing

Program.cs

/* This is an experimental script which I used to successfully clear the "Service High Voltage Charging System" message which can occur due to a loss of isolation.
 * Previously I had to pay frequently to access the expensive SPS programming system to clear this code whilst attempting to resolve the underlying cause.
 * This script was generated by a tool I developed to analyse J2534 log files.
 * This could work for other cars but I can't comment on success. Please do not run this unless you understand the consequences!
 * I intend to convert to a version that will work with ELM327 once I learn how these work.
 * The program requires the J2534-Sharp library as a dependency.

Which tool do I need to input this code?

Hello cjdell,

I am also very much interested in your program, can you tell more?
regards

Seems to be in c-sharp (aka c#) language as the filename ends in .cs extension. Perhaps meant to be developed with visual studio on windows. Not sure about the J2534 library but might be something like this: https://github.com/BrianHumlicek/J2534-Sharp. I need to clear those codes so I may experiment with this and post back here. Actually these are just wild guesses... I could be completely wrong about any/all of the above ;-) In past I've used the pirated GM dts2 software provided by the makers of vx-diag obd2 dongle, but that software is flagged as having trojan viruses by windows. This gist is talking to a vx-diag dongle (in line 25) so I am guessing the purpose was to have a way to clear the codes without having to use the pirated software.

Has anyone been able to use this or know how to ?
