OK: END 

1. Check that the power window can be operated with the power window regulator switch.

   OK: Manual UP/DOWN function operates normally. 

NG: OTHER PROBLEM (See  PROBLEM SYMPTOMS TABLE   ) 

OK: GO TO NEXT STEP 

1. Check that the power window can be operated with the power window regulator switch.

   OK: AUTO UP/DOWN function operates normally. 

NG: OTHER PROBLEM (See  AUTO UP/DOWN FUNCTION DOES NOT OPERATE ON PASSENGER SIDE   ) 

OK: GO TO NEXT STEP 

1. Disconnect the P12 regulator switch connector.
2. Turn the ignition switch ON.
3. Using an oscilloscope, check the waveform of the connector.

   Standard: 

   The waveform is shown in  Fig 2  .

NG: Go to step 5 

OK: REPLACE POWER WINDOW REGULATOR SWITCH ASSY (PASSENGER SIDE) 

1. Disconnect the P12 regulator switch connector.
2. Disconnect the P9 regulator master switch connector.
3. Measure the resistance of the wire harness side connectors.

   Standard: 

   POWER WINDOW REGULATOR MASTER SWITCH ASSY TERMINAL RESISTANCE
   
   

   Tester Connection	Specified Condition
   P12-2 (MPX1) - P9-7 (MPX1)	Below 1 Ω
   P12-2 (MPX1) - Body ground	10 kΩ or higher

NG: REPAIR OR REPLACE HARNESS AND CONNECTOR 

OK: GO TO NEXT STEP 

1. Remove the master switch but do not disconnect the connector.
2. Turn the ignition switch ON,
3. Measure the voltage of the connector.

   Standard: 

   POWER WINDOW REGULATOR MASTER SWITCH ASSY TERMINAL VOLTAGE
   
   

   Tester Connection	Window Lock Switch Condition	Specified Condition
   P9-6 (PCT) - Body ground	OFF (Normal)	10 to 14 V
   P9-6 (PCT) - Body ground	ON (Lock)	Below 1 V
