HI,

I am sorry that you have not been helped yet. I just came online and saw your question.

Ok, because I dont know the quality of the scan tool used, did you use one of the simple code readers to try to retrieve the codes and if so, the brand and model, or did you have Autozone or other parts store try to read it for codes?

I have to ask because low end code readers such as the parts stores use and you can buy for under $200 are not able to read VSC, Traction Control or 4wd control modules.

HI,

Ok, can you get me the model number so I can make sure if it reads these control modules or not. That will tell us the direction we need to go in

HI,

I see where it reads powertrain, SRS/Airbag and ABS codes, but not VSC, Trac control or 4wd codes.
