I have found that sometimes, there is damage to the OBD port for diagnostics. Some will not be read, no matter what scanner is used.
Talk about FRUSTRATING! They show an error code, but you can't READ IT!
ARGH!
I just checked the link and it worked for me fine. For you to get to the down; to get the software you want, take another look at the post. First, I tell you how to find the answers and then provide the answer.
I instructed: "Use Google. Ask our beneficent master for "Drivers Autel Maxiscan MS 509 Win XP" and you'll see a few links."
Finding your own answers is a WHOLE lot faster, my friend and will make you strong. Strong enough to help others.
For me, I do not expect to be able to see much longer which is going to make typing awfully tough! So, I want you all to be able to serve yourself as I have done. When you can, I will have done my job as my creator has given.
Now, get out there and find what you need. If it's too frustrating, choose a different tool and get your money back-or resell it in E-bay...
