Component Inspection

Check Intake actuator
1. Ignition "OFF"
2. A/C-ECU, Intake actuator : Disconnect.
3. Connect (+) terminal of battery to FRE (+) of intake actuator and (-) terminal to REC (-). (Component side)
4. Verify that the actuator operates to the REC position
5. Verify that the temperature actuator operates to the FRE position with reverse connecting. (REC (-) and FRE (+)) (Component side)
A. Specification : Refer the specifications in fig. 1








6. Is "Door position" display near the specified value ?
YES
1) Go to "Check potentiometer" procedure.
NO
1) 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
1. Ignition "OFF"
2. A/C-ECU : Connect, Intake actuator : Disconnect.
3. Ignition "ON" (ENGINE "OFF").
4. Measure voltage between Signal (F/B) terminal of Intake actuator harness connector and and chassis ground. (Component side)
A. Specification : Refer the specifications in fig. 2








5. Is "voltage" display near the specified value ?
YES
1) 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
1) 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.
