To make any permanent change to your vehicle calibration requires the Scan and Tune products. Scan Only products cannot flash an ECM controller and therefore cannot make permanent changes. In the Scan Tool the fan on/off can likely be commanded by using the DVT (bi-directional) controls.

As Tordne said:
- you need the tunetool and the hardware/cable to edit the fan settings.
- the scantool lets you exercise the fans, but not change their settings.
