Vehicles With Exterior Open/close Function

1. Measure the voltage at each terminal is as indicated in the Terminal Voltage Tables.

• If the voltage is not as specified in the terminal voltage table, inspect the parts under “Inspection item (s)”.

― If the system does not work properly even though the parts or related wiring harnesses do not have any malfunction, replace the power window subswitch.

1. Turn the ignition switch to ON position, and verify the LED illuminates.

• If not as specified, replace the power window subswitch.

Vehicles Without Exterior Open/close Function

1. Verify continuity as indicated in the table.

2. Connect battery positive voltage to terminal E and ground to the terminal A. Verify that continuity exists.

• If not as specified, replace the power window subswitch.

3. Connect battery positive voltage to terminal E and ground to the terminal B. Verify that continuity exists.

• If not as specified, replace the power window subswitch.
