The logic module uses this sensor to determine if the A/C compressor clutch is to be engaged by the switch. The clutch may not be engaged because this switch is superseded by the A/C cutout relay. Is uses this information to open the AIS motor to compensate for the extra load from the compressor and to increase the target idle speed to 1000rpm for proper A/C performance at idle.
