1. An integrated thermal management system for an electrified vehicle, comprising:
at least one multi-position valve configured to selectively direct a coolant within a first circuit, a second circuit, a third circuit, and a fourth circuit of a coolant system;
the first circuit of the coolant system is configured to receive a first portion of the coolant for thermally managing a traction battery pack;
the second circuit of the coolant system is configured to receive a second portion of the coolant for thermally managing a power electronics module;
the third circuit of the coolant system is configured to receive a third portion of the coolant for addressing a passenger cabin heating load;
the fourth circuit of the coolant system is configured to receive a fourth portion of the coolant for addressing a passenger cabin cooling load; and
a control unit configured to selectively control the at least one multi-position valve to manage a flow of each of the first portion, the second portion, the third portion, and the fourth portion of the coolant based on a thermal control mode of the integrated thermal management system.
