| 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
|
| 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 main crash pad assembly.
(Refer to Body - "Main Crash Pad Assembly")
|
| 3. |
Separate the connector (A) and loosen the mounting screws and remove
the intake actuator (B).
|
| 4. |
To install, reverse the removal procedure.

Description The intake actuator is located at the blower unit. It regulates the intake door by a signal from the control unit. Pressing the intake selection switch will shift between recirculation and fresh air modes.
Troubleshooting Problem Symptoms Table Before replacing or repairing air conditioning components, first determine if the malfunction is due to the refrigerant charge, air flow or compressor. Use the table below to help you find the cause of the problem.
Description The PTC (Positive Temperature Coefficient) heater is installed at the exit or the backside of heater core. The PTC heater is an electric heater using a PTC element as an auxiliary heating device that supplements deficiency of interior heat source in highly effective diesel engine.
