Climate Control System - Vehicles With: Electronic Manual Temperature Control (EMTC) - System

the recirculated air request button is enabled. If the recirculated air request button is selected (indicator on), the air inlet door closes, preventing outside air from entering the passenger compartment. If the recirculated air request button is not selected (indicator off), the air inlet door opens, allowing only outside air into the passenger compartment. the air distribution doors operate in combination to direct airflow to the floor duct, the defroster duct and the side window demisters. blended air temperature is available. Only when A/C compressor operation has been selected by pressing the A/C button (indicator on) can the airflow temperature be cooled below the outside air temperature. the blower motor is on and the speed is adjustable.

DEFROST

When DEFROST mode is selected:

the recirculated air request button is disabled. The air inlet door opens, allowing only outside air into the passenger compartment. the air distribution doors operate in combination to direct airflow to the defroster duct and side window demisters. A small amount of airflow from the floor duct is present. the A/C is turned on in defrost mode. The A/C compressor operates as long as the outside temperature is above approximately 32.0°F (°C). blended air temperature is available. the blower motor is on and the speed is adjustable.

MAX DEFROST

When MAX DEFROST mode is selected:

the recirculated air request button is disabled. The air inlet door opens, allowing only outside air into the passenger compartment. the air distribution doors operate in combination to direct airflow to the defroster duct and side window demisters. A small amount of airflow from the floor duct is present. the A/C is turned on in defrost mode. The A/C compressor operates as long as the outside temperature is above approximately 32.0°F (°C). the temperature is set to the highest setting and is not adjustable. the fan is set to the highest speed and is not adjustable.

Remote Start

Remote start is an optional feature available on this vehicle. In addition to being able to start the vehicle remotely, the remote start feature also utilizes other vehicle systems to increase the level of comfort to the vehicle occupants upon entering the vehicle. Additional information on the remote start feature and the other vehicle systems, refer to Owner's Literature.

When the factory remote start feature is used, the EMTC system runs at the setting it was set to when the vehicle was last turned off. You cannot adjust the climate control system during remote start operation. Turn the ignition on to return the system to its previous settings.

Set the climate control to operate using the last climate control settings through the information display setting: Remote Start > Climate Control > Heater–A/C > Last Settings, refer to the Owner's Literature for more information.

Component Description

FCIM - Electronic Manual Temperature Control (EMTC)

The EMTC system uses the FCIM as the HVAC control module. The FCIM also controls the outputs for rear window defrost and climate controlled seats. For details on the FCIM communication, refer to Control System Logic in this section.

The FCIM utilizes a Field-Effect Transistor (FET) protective circuit strategy for its actuator outputs. Output load (current level) is monitored for excessive current (typically short circuits) and is shut down (turns off the voltage or ground provided by the module) when a fault event is detected. A short circuit DTC is stored at the fault event and a cumulative counter is started.
