| Inspection |
| 1. |
Turn the ignition switch OFF. |
| 2. |
Disconnect the intake actuator connector. |
| 3. |
Verify that the intake actuator operates to the fresh position when connecting 12V to terminal 3 and grounding terminal 4.
Verify that the intake actuator operates to the recirculation position when connected in reverse.
|
| 4. |
Connect the intake actuator connector. |
| 5. |
Turn the ignition switch ON. |
| 6. |
Check the voltage between terminal 6 and 5.
Specification
It will feedback the current position of the actuator to controls. |
| 7. |
If the intake actuator does not operate well, substitute with a known-good intake actuator and check for proper operation. |
| 8. |
Replace the intake actuator if it is proved that there is a problem with it. |
| Diagnosis With GDS |
| 1. |
The heating, ventilation and air conditioning can be quickly diagnosed failed parts with vehicle diagnostic system (GDS).
? The diagnostic system (GDS) provides the following information.
(1) Self diagnosis: Checking the failure code (DTC) and display.
(2) Current data: Checking the system input/output data state.
(3) Actuation test: Checking the system operation condition.
(4) Additional function: Other controlling such as he system option and zero point adjustment. |
| 2. |
Select the 'Car model' and the system to be checked in order to check the vehicle with the tester. |
| 3. |
Select the 'Current data' menu to search the current state of the input/output data.
The input / output data for the sensors corresponding to the Intake Actuator can be checked.
|
| 4. |
To perform compulsory operation on Intake Actuator input factors, select "ACTUATION TEST".
|
| Replacement |
| 1. |
Disconnect the negative (-) battery terminal. |
| 2. |
Remove the glove box housing.
(Refer to Body - "Glove Box Housing") |
| 3. |
Remove the passenger's side shower duct (A) after loosening the screw.
|
| 4. |
Disconnect the connector (A) and then remove the intake actuator (B) after loosening the mounting screws.
|
| 5. |
Install in the reverse order of removal. |
