General Information

Component Location





General Description

The temperature control actuator is located at the heater unit. The actuator consists of a motor and feedback potentiometer that is used by the A/C ECU to control air temperature and to monitor actuator operation. Temperature control actuator regulates the temperature by the procedure as follows. Signal from control unit adjusts position of temp door by operating temp motor and then temperature will be regulated by the hot/cold air ratio decided by position of temp door. In operation, potentiometer delivers temp door position transformed into voltage value to A/C ECU.

DTC Description

B2415 will set if the mode actuator has not responded to an A/C ECU actuation signal for over 40 seconds.

DTC Detecting Condition





Specification

** Voltage value of Air Mix potentiometer as a function of temp door position.
