Hyundai i-30: Engine Control System / Thermal Management Module (TMM) Motor
Description and operation
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.
