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 

      MEASUREMENT ITEM

      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: 

      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 OVERHAUL ).
      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

      Terminal No. Motor Gear Rotation
      Battery positive voltage --> 2
      Battery negative voltage --> 1      		 Clockwise
      Battery positive voltage --> 1
      Battery negative voltage --> 2      		 Counterclockwise
    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 
  4. INSPECT POWER WINDOW REGULATOR MASTER SWITCH ASSY (FOR POWER SOURCE) 
    1. Check the voltage between the terminals.

      Standard: 

      SPECIFIED CONDITION

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