Without Exterior Open function
- Measure the voltage at each terminal (other than terminals A, H and G).
- If the voltage is not as specified in the Terminal Voltage Table, inspect the parts under "inspection item(s)" and related wiring harnesses.
- Disconnect the negative battery cable.
- Inspect the power window main switch connector for continuity at terminal G.
- 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.
