Note

• Before proceeding with diagnosis of malfunctioning power windows, ensure the POWER WINDOW INITIALIZATION PROCEDURE has been performed.

Auto-Open/Close (All Door’s)

1.Measure the voltage at each terminal (except terminals 1A and 1D).

• If the voltage is not as specified in the Terminal Voltage Table (Reference), inspect the parts under Inspection item(s) and related wiring harnesses.

2.Disconnect the negative battery cable.

3.Inspect the power window main switch connector for continuity at terminals 1A and 1D.

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.
