Hyundai i30 (PD) 2018-2025 Service Manual / Engine Control / Fuel System / Engine Control System / Thermal Management Module (TMM) Motor

Description and operation

Description

Integrated thermal management module (ITM) is a device that controls the coolant flow rate according to coolant temperature. At initial startup, the integrated thermal management module (ITM) quickly warms up the engine by controlling the flow of the coolant and this fast warm-up helps improve the fuel efficiency. When the coolant temperature rises, the integrated thermal management module (ITM) adjusts the cooling water temperature by controlling the valves to regulate the flow of coolant through a radiator or heater.
