Chevy Volt / Opel Ampera SHVCS DTC Clearing
Raw
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.
* https://github.com/BrianHumlicek/J2534-Sharp
