1. 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 main switch.

1. Verify that the continuity between the power window main switch terminals is as indicated in the table.
If not as indicated in the table, replace the power window main switch.
2. Apply battery positive voltage to terminal I, and connect the ground to terminal J, and then verify that the light emitting diode illuminates.
If not as specified, replace the power window main switch.
