POWER WINDOW MAIN SWITCH INSPECTION


id091200002100

Note
•  The power outer mirror switch is built into the power window main switch.

1.  Disconnect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.)

2.  Remove the power window main switch. (See POWER WINDOW MAIN SWITCH REMOVAL/INSTALLATION.)

3.  Connect the power window main switch connector.

4.  Connect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.)

5.  Verify that the voltages of each of the terminals are as indicated in the terminal voltage table (reference).

•  If the voltage is not as specified in the terminal voltage table (reference), inspect the parts under Inspection item(s) and related wiring harnesses.
―  If the system does not work normally even though the inspection items are normal, replace the power window main switch.
