I read with interest the info in prior thread: www.toyota-4runner.org/problems-warranty-issues/32818-one-cause-fix-vsc-trac-vsc-off-lights-zero-point-calibration.html
So I just got back from having the A/C serviced and a LOF done at a local independent shop. I noticed as I was pulling away that the VSC Trac and VSC Off warning lights came on (and stayed on) as the vehicle started to move, but I didn't have time to turn around and ask them why. After I got home, I checked here and found the thread noted above, so after reading the first few pages, I called the shop and asked if they had hooked up a code reader to it for some reason. The owner didn't ask his tech, but he said initially they wouldn't have had any reason to. When I told him it looks like the zero point calibration memory had been tripped or erased somehow, he said it's possible to have that happen if they had the wheels off the ground, in gear and the tires spinning, so the car sees the wheels moving but the car ISN'T moving, causing hate and discontent somehow.
Anyway, he asked me to bring it back and he'd have them perform the calibration at no charge, so I'll do that tomorrow. But then I got to thinking, they also reset the "MAINT" light when they did the oil service....wouldn't they normally use a reader for that? When I've reset it, I've just followed the manual procedure (can't remember exactly what it is right now but I keep it in my console) which takes all of a minute, but I bet the shops use a reader.
Anyway, anyone else had these lights come on after a service like this, for the reason he described? Or is it more likely they induced it clearing my MAINT light?
