Overview

The cabin coolant heater system provides warm coolant to the heater core to warm the passenger compartment whenever the front DATC module requests heat and the HEV is in a driving mode, remote started, or doing Cabin Drive Conditioning.

The climate control system uses the cabin coolant heater to heat the passenger compartment in place of the heater core in low ambient temperatures. Once engine coolant reaches a sufficient temperature to heat the passenger compartment, the climate control system stops using the cabin coolant heater.

The cabin coolant heater system consists of the following components:

Cabin heater coolant pump
Cabin coolant heater
Cabin heater coolant diverter valve
Heater core
Cabin heater coolant temperature sensor
