When coolant temperature reaches approximately 103°C (218°F) , or when air conditioning is requested, the powertrain control module (PCM) provides a ground path for the fan relay. This ground is provided to the cooling fan relay through pin C2 of PCM connector C3. Battery voltage is then applied to the fan through the relay. When coolant temperature drops below approximately 98°C (209°F) , the PCM opens the ground path to the relay. This will prevent the cooling fan from being energized.
