Repair Procedures: Inspection

  1. Ignition "OFF"
  2. Disconnect the connector of temperature control actuator.
  3. Verify that the temperature control actuator operates to the hot position when connecting 12V to the terminal 3 and grounding terminal 4.

    Verify that the temperature control actuator operates to the cool position when connecting in the reverse.

  4. Check the voltage between terminals 5 and 6.

    Specification 

    VOLTAGE SPECIFICATION

    Door position Voltage (5-6) Error detecting
    Max. cooling 0.45 ± 0.15V Low voltage: 0.1V or less
    Max. heating 4.55 ± 0.15V High voltage: 4.9V or more

    * It will feedback current position of actuator to controls.

  5. If the measured voltage is not within specification, substitute with a known-good temperature control actuator and check for proper operation.
  6. If the problem is corrected, replace the temperature control actuator.
