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.
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 |
Check the voltage between terminals 7 and 7(Drive).
Check the voltage between terminals 5 and 6(Passenger).
Door position | Voltage(3-4) | 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.
