decreased, fan speed will increase.
When adjusting maximum fan speed and maximum is exceeded, decrease fan speed to
1,000 rpm and then increase fan speed to maximum fan speed. This will allow fan speed
to be properly set.
Calibration procedure will bestopped for diagnostic or event codes. Correct condition that
caused code and restart calibration.
