Repair Procedures: Inspection
WARNING: This page is about a different variant/trim than selected.
- 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 3 and grounding terminal 7.
Verify that the temperature control actuator operates to the cool position when connecting in the reverse.
[Drive]
- Check the voltage between terminals 4 and 5 (Drive).
Specification
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 [Passenger]
- Check the voltage between terminals 4 and 5 (Passenger).
Specification
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.
