Ignition "OFF".
Disconnect the connector of temperature control actuator.
Verify that the temperature control actuator operates to the hot position when connecting 12V to the terminal 1 and grounding terminal 2.
Verify that the temperature control actuator operates to the cool position when connecting in the reverse.
Check the voltage between terminals 4 and 5.
Door position | Voltage (4-5) | Error detecting |
Max. cooling | 0.3 ± 0.15V | Low voltage : 0.1V or less |
Max. heating | 4.7 ± 0.15V | High voltage : 4.9V or more |
* It will feedback current position of actuator to controls.
If the measured voltage is not specification, substitute with a known-good temperature control actuator and check for proper operation.
If the problem is corrected, replace the temperature control actuator.
Disconnect the negative (-) battery terminal.
Remove luggage side trim (Refer to BD group- interior trim)
Loosen the mounting screw and then remove the temperature control actuator (A).
Installation is the reverse order of removal.
