INSPECTION PROCEDURE 

1. CHECK POWER WINDOW REGULATOR MASTER SWITCH ASSY 
   1. Using the hand-held tester, check operation of the master switch using the data list.

   Standard: 

   Data list in D-DOOR ECU 

   DATA LIST
   
   

   Measurement Item	Label	Parameter
   Driver switch on master switch	P/W AUTO SW	ON/OFF

   1. NG: Go to step   3 
   2. OK: Go To Next Step 
2. CHECK WIRE HARNESS (MASTER SWITCH @ MOTOR) 
   1. Disconnect the D18 master switch connector.
   2. Remove the front door trim LH.
   3. Disconnect the P10 power window motor connector.
   4. Check the continuity between the wire harness side connectors.

      Standard: 

      TERMINAL NO AND SPECIFIED CONDITION
      
      

      Terminal No.	Specified Condition
      D18-11 <=> P10-1	Continuity
      D18-1 <=> P10-2	Continuity
      D18-1 <=> Body ground	No continuity
      D18-11 <=> Body ground	No continuity

   5. Reference:

   Check operation of the power window motor (driver side).

   1. Remove the motor (See page 75-13).
   2. Apply battery voltage to the connector between terminals 1 and 2.
   3. Check that the motor rotates smoothly.
   NOTE: Do not apply battery voltage to the terminals except 1 and 2.

   Standard: 

   TERMINAL NO AND MOTOR GEAR ROTATION
   
   

   Terminal No.	Motor Gear Rotation
   Battery positive voltage --> 2	Clockwise
   Battery negative voltage --> 1
   Battery positive voltage --> 1	Counterclockwise
   Battery negative voltage --> 2

   1. NG: REPAIR OR REPLACE HARNESS AND CONNECTOR 
   2. OK: REPLACE POWER WINDOW REGULATOR MOTOR ASSY LH (DRIVER SIDE) 
3. INSPECT POWER WINDOW REGULATOR MASTER SWITCH ASSY (FOR GROUND) 
   1. Remove the master switch (the connector is connected).
   2. Check the continuity between terminal 2 and the body ground.

   Standard: Continuity 

   1. NG: REPAIR OR REPLACE HARNESS AND CONNECTOR 
   2. OK: Go To Next Step

   1. Check the voltage between the terminals.

   Standard: 

   TERMINAL NO AND SPECIFIED CONDITION
   
   

   Terminal No.	Condition	Specified Condition
   9 <=> 2	Constant	10 - 14 V
   20 <=> 2	Ignition ON	10 - 14 V
   10 <=> 2	Constant	10 - 14 V

   1. NG: REPAIR OR REPLACE HARNESS AND CONNECTOR (POWER SOURCE CIRCUIT) 
   2. OK: REPLACE POWER WINDOW REGULATOR MASTER SWITCH ASSY
