Diagnostic Procedure

STEP

INSPECTION

ACTION

1

VERIFY CLIMATE CONTROL UNIT CONNECTOR CONDITION

•  Switch the ignition off.

•  Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5 (WITHOUT i-stop)].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].)

•  Disconnect the climate control unit connectors.

•  Inspect the connector and terminals (corrosion, damage, pin disconnection).

•  Are the connector and terminals normal?

Yes

Go to the next step.

No

Repair/replace the malfunctioning vehicle wiring harness, connector, or terminal.

After repair procedure, go to the next step.

2

VERIFY CONNECTOR CONDITION

•  Disconnect the following each sensor/actuator connectors.

―  Air mix actuator (See AIR MIX ACTUATOR REMOVAL/INSTALLATION [FULL-AUTO AIR CONDITIONER].)

―  Airflow mode actuator (See AIRFLOW MODE ACTUATOR REMOVAL/INSTALLATION [FULL-AUTO AIR CONDITIONER].)

―  Solar radiation sensor (See SOLAR RADIATION SENSOR REMOVAL/INSTALLATION [FULL-AUTO AIR CONDITIONER].)

•  Inspect the connector and terminals (corrosion, damage, pin disconnection).

•  Are the connector and terminals normal?

Yes

Go to the next step.

No

Replace the malfunctioning part.

After replace procedure, go to the next step.

3

INSPECT EACH SENSOR/ACTUATOR

•  Inspect the following each sensor/actuator connectors.

―  Air mix actuator (See AIR MIX ACTUATOR INSPECTION [FULL-AUTO AIR CONDITIONER].)

―  Airflow mode actuator (See AIRFLOW MODE ACTUATOR INSPECTION [FULL-AUTO AIR CONDITIONER].)

―  Solar radiation sensor (See SOLAR RADIATION SENSOR INSPECTION [FULL-AUTO AIR CONDITIONER].)

•  Is it normal?

Yes

Go to the next step.

No

Replace the malfunctioning sensor/actuator.

After replace procedure, go to the next step.

4

INSPECT EACH SENSOR/ACTUATOR CIRCUIT FOR SHORT TO GROUND

•  Inspect for continuity between the following terminal (wiring harness-side) and body ground:

―  Climate control unit terminal 1L

•   Is there continuity?

Yes

Repair the wiring harness.

Go to the next step.

No

Go to the next step.

5

VERIFY THAT SAME DTC IS NOT OUTPUT AGAIN

•  Reconnect the disconnected connectors.

•  Connect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5 (WITHOUT i-stop)].) (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].)

•  Clear the past malfunction from memory.

•  Verify DTCs.

•  Is DTC U200D:11 output?

Yes

Repeat the inspection from Step 1.

•  If the malfunction does not recur, go to the next step.

•  If the malfunction recurs, replace the climate control unit. (See CLIMATE CONTROL UNIT REMOVAL/INSTALLATION [FULL-AUTO AIR CONDITIONER].)

Go to the next step.

No

Go to the next step.

6

VERIFY THAT NO OTHER DTCs ARE PRESENT

•  Verify other DTCs displayed.

•  Are any other DTCs output?

Yes

Perform the corresponding DTC inspection.

No

DTC troubleshooting completed.
