SD tune service vehicle light on??
no codes. the service engine light is not on. the "service vehicle" one is. like when you have the cable hooked up to the laptop tuning it, that light comes on. now it wont turn off.

The PCM loses connection to other modules in the 20 or so seconds it takes to wite a VCM. On my car, the light is always on.

I covered this in a post not too long ago...if you go to each of the codes for P0101-0103, and turn them to "SES Off" (actually click on the little circle), you will take care of this problem. Make sure you set the other part of the settings to "No MIL Light"...as long as you don't set it to "No Error Reported", it will still set the necessary codes to get into Speed Density mode, but now you won't have any of the annoying lights.
