Code P0480 2016 Chevrolet Silverado Description
The cooling fan speed is affected by many different conditions and the ECM will adjust the duty cycle from 0 - 100 percent based on cooling system requirements.

When multiple cooling fan speed requests are received, the ECM operates the fan at the highest speed requests.
