I just went through 3 months and $600 of VSM hell on the Excursion. Ask away, I know eveything about this hell. Here are a few tips.
1. The Ford tool refers to it as the CSM. (no where does it say VSM)
2. If Ford tool cannot communicate with your old VSM they must log into the Ford tech site and get your "as built" codes to enter.
3. To enter this info they call the Ford tech help line and get a code to enter that allows them to go into a manual entry mode where they then enter the "as built" info.
Ask more questions with specifics or PM me. I know 2002's are very prone to the VSM failing. Both of mine did.
