Riddle me this...
1) How can you have a DTC disabled and still get a mil light?
2) How can HPT show a DTC, go to clear it and it doesn't go away but when you read it with GM GDS it shows no code. I think I believe the GM tool first......
There is definitely something wrong with how HPT is reading and address the DTC function. This is very frustrating and I'm not sure why this has been going on this long. I have sent enough to support and its just looked at like its not reallt a problem......but it is....what is different with how the E92 deals with this?
