Service light with WRENCH stays on, despite two oil changes and numerous re-sets

Thank you, Scott, however this is just putting a band-aid on the problem. As I stated in my original post, this procedure has been done numerous times by my mechanic, Jason from your service department, and myself, and it doesn't resolve the problem. It goes off for a minute or two, but comes back on. I had the oil changed in October and no light came on, but in late June the Service light with wrench came on, so I had it serviced in late June. They did another oil change (per service manual) "replaced a vehicle speed sensor and replaced a wheel speed signal conditioner module," per their diagnostic tests and the light remains on. My auto shop ran out of codes to check with their scanner, so recommended a Chevie dealership to perhaps have the computer "reflashed or reset." I am bringing my Vue in again on Wednesday, the 9th, and I'm requesting a diagnostic check using your more extensive computer. Will that tell the mechanic if the computer just needs to be reset? BTW, it appears I'm not the only 2002 Vue owner with this problem, but my Vue only has 27,000 miles on it and has been kept in very good condition-everything works and it runs well. Any further advice is appreciated.
