Component Inspection
WARNING: This page is about a different variant/trim than selected.
■ Check Intake Actuator
- Ignition "OFF"
- Disconnect Intake actuator and connect A/C control unit main harness connector.
- Connect (+) terminal of battery to FRE (+) of intake actuator and (-) terminal to REC (-) (Component Side).
- Verify that the actuator operates to the FRE position.
- Verify that the Intake actuator operates to the REC position with reverse connecting (REC (+) and FRE (-)) (Component Side).
Specification : (Refer the Specifications in Fig.1)
(Fig.1)
Actuator Harness FRE (+) REC (-) Door Position Battery Terminal 12 V ground FRE ground 12 V REC (Fig.1) * Function of the actuator motor according to terminal connection type (Observe Safety Regulations).
- Is "Door Position" display near the specified value?
YES
- Go to "CHECK POTENTIOMETER " procedure.
NO
- Substitute with a known-good Intake actuator and check for proper operation. If the problem is corrected, replace Intake actuator and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
■ Check Potentiometer
- Ignition "OFF"
- Disconnect Intake actuator and A/C control unit main harness connector.
- Ignition "ON" (ENGINE "OFF").
- Measure voltage between Signal (F/B) terminal of Intake actuator harness connector and chassis ground (Component Side).
Specification : (Refer the Specifications in Fig.2)

Door Position Voltage FRE 0.3 ± 0.15V REC 4.7 ± 0.15V (Fig.2) * Voltage value of intake potentiometer as a function of intake door position.
- Is "Voltage" display near the specified value?
YES
- Check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NO
- Substitute with a known-good Intake actuator and check for proper operation. If the problem is corrected, replace Intake actuator and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
