- Check Actuation Test Connect scantool with diagnostic connector. Warm up the engine to normal temperature after engine start. Select "Intake Potentiometer" parameter on the current data with scantool. Perform Actuation Test for Air Inlet Mode Selection - Recirculation/Fresh in order. With performing Actuation test, check that the value of each position sensors are changing. Specification : Recirculation : About 90%, Fresh : About 10%. Are the value of each position sensors changed when performing actuation test? YES This may be a intermittent problem caused by poor contact of component or the Control Unit. Thoroughly check for looseness, poor connection, bent, corrosion, contamination, deformation or damage of connector. Monitoring with a DVOM on min/max or VMI while wiggling connectors may help find the problem. Any change in voltage indicate a possible problem. Repair or replace as necessary and then, go to «VERIFICATION OF VEHICLE REPAIR»(ref-429644-S40637982582011101500000) procedure.

- Actuation Test Connect scantool with diagnostic connector. Warm up the engine to normal engine temperature after engine starts. Select and monitor "Direction Potention" parameter on scantool. Select and perform Actuation test Driver Mode Door - Face / Foot / Defrost in order. Check that the value of all the parameters are changed when performing the actuation test. Specification : Face - About below 10%, Foot : About 50%, Defrost : About 90%. Are all the parameters changed when performing Actuation test? YES This may be a intermittent problem caused by poor contact of component or the Control Unit. Thoroughly check for looseness, poor connection, bent, corrosion, contamination, deformation or damage of connector.

- Check Actuation Test Connect scantool with diagnostic connector. Warm up the engine to normal temperature after engine start. Select "Air Mix Door Potentiometer-Passenger" parameter on the current data with scantool. Perform Actuation Test for "Passenger Air Mix Door - 0% / 50% / 100%. With performing Actuation test, check that the value of Air Mix Door Potentiometer is changed and close to the value of Actuation Test. Specification : Check that the value of Air Mix Door Potentiometer at current data should be close to the value of the actuation test. Does the value of current data follow in accordance with the each actuation test? YES This may be a intermittent problem caused by poor contact of component or the Control Unit. Thoroughly check for looseness, poor connection, bent, corrosion, contamination, deformation or damage of connector.
