TEMPERATURE REGULATION-HEATING
The E46 uses one water valve/heater core as part of interior temperature regulation. The
water valve is pulsed to control the flow of coolant through the heater core as on other sys-
tems.
Temperature regulation is based on the inputs from:
• Temperature control switch
• Interior temperature sensor
• Ambient temperature signal
• Heater core sensor
• Evaporator temperature signal
• "Y" factor
The rocker switch is used to select the desired cabin temperature which is displayed in the
matrix of the control panel. The range for temperature display is from 60 to 90 ° F.
SERVICE STATION FEATURE - The "Service Station" feature introduced with the E38 IHKA
is integrated into the E46 IHKA. This prevents the heater core from being flooded with hot
coolant when refueling the vehicle.
