1. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.5].)
2. Remove the power window subswitch. (See POWER WINDOW SUBSWITCH REMOVAL/INSTALLATION.)
3. Connect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.5].)
4. Connect the power window subswitch connector.
5. Measure the voltage at each terminal.
If the voltage is not as specified in the terminal voltage table, inspect the parts under “Inspection item(s)” and related wiring harnesses.
If the system does not work properly even though the inspection items or related wiring harnesses do not have any malfunction, replace the power window subswitch.

1. Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.5].)
2. Remove the power window subswitch. (See POWER WINDOW SUBSWITCH REMOVAL/INSTALLATION.)
3. Verify that the continuity is as indicated in the table using a tester.
If not as indicated in the table, replace the power window subswitch.
