Ignition "OFF"
Disconnect Intake actuator and A/C control Module main harness connector.
Connect (+) terminal of battery to FRE(+) of intake actuator and (-) terminal to REC(-). (Component side)
Verify that the Intake 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)
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?
 | ▶ Go to "Check potentiometer" procedure. |
 | ▶ 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. |
Ignition "OFF"
Disconnect Intake actuator and A/C control Module 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?
| ▶ 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. |
| ▶ 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. |
