To disable VATS you must do the following:
1. Set the VATS value to "PWM"
2. Set DTC P1626 to "3 - No Error Reported"

Additionally you might need to set
4. Set DTC P1630 to "3 - No Error Reported"

If you have problems please email your file and a scanner log while logging the VATS status pid to support.
