1. Measure the voltage at each terminal (other than terminals H and I).
2. Disconnect the negative battery cable.
3. Inspect the power window main switch connector for continuity at terminals H and I.
4. 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.
