Inspection Procedure

  1. CHECK AUTO UP/DOWN FUNCTION (DRIVER SIDE) 
    1. Check that the power window AUTO UP/DOWN function operates normally.

      HINT:

      • If the function works normally, go to step A.
      • If the function with the driving position memory switch does not work normally, go to step B.
      • If the function without the driving position memory switch does not work normally, go to step C.
    1. B: Go to step 2. 
    2. C: Go to step   4 . 
    3. A: REPLACE POWER WINDOW REGULATOR MASTER SWITCH ASSY 
  2. W/DRIVING POSITION MEMORY SWITCH: CHECK POWER SOURCE (FUSE) 
    1. Check that the remote control mirror functions operate normally.
    1. NG: Go to step   4 . 
    2. OK: Go to next step. 
  3. PERFORM ACTIVE TEST USING HAND-HELD TESTER 
    1. Select the ACTIVE TEST, use the hand-held tester to generate a control command, and then check that the driver side power window operates.

      Standard (Power window regulator master switch (Driver door ECU)): 

      POWER WINDOW REGULATOR MASTER SWITCH (DRIVER DOOR ECU)

      Item Test Detail
      P/W UP/DOWN Operates power window UP/DOWN
    1. NG: Go to step   6 . 
    2. OK: REPLACE POWER WINDOW REGULATOR MASTER SWITCH ASSY 
  4. INSPECT FUSE (ECU-B, ECU-IG NO. 1, PWR) 
    1. Remove the ECU-B fuse from the F/L block.
    2. Remove the ECU-IG NO. 1 fuse and PWR M-fuse from the instrument panel J/B.
    3. Check the resistance.

      Standard: Below 1 Ω 

    1. NG: REPLACE FUSE 
    2. OK: Go to next step. 
  5. PERFORM ACTIVE TEST USING HAND-HELD TESTER 
    1. Select the ACTIVE TEST, use the hand-held tester to generate a control command, and then check that the driver side power window operates.

      Standard (Power window regulator master switch (Driver door ECU)): 

      POWER WINDOW REGULATOR MASTER SWITCH (DRIVER DOOR ECU)

      Item Test Detail
      P/W UP/DOWN Operates power window UP/DOWN
    1. NG: Go to step   8 . 
    2. OK: REPLACE POWER WINDOW REGULATOR MASTER SWITCH ASSY 
  6. CHECK WIRE HARNESS (FOR POWER SOURCE OF POWER WINDOW REGULATOR MASTER SWITCH ASSY) 
    1. Disconnect the P22 master switch connector.
    2. Check the voltage between the wire harness side connector and the body ground.

      1. NG: REPAIR OR REPLACE HARNESS AND CONNECTOR 
      2. OK: Go to next step. 
  7. CHECK WIRE HARNESS (FOR GROUND SOURCE OF POWER WINDOW REGULATOR MASTER SWITCH ASSY) 
    1. Disconnect the P22 master switch connector.
    2. Check the resistance between the wire harness side connector and body ground.

      Standard: 

      FOR GROUND SOURCE OF POWER WINDOW REGULATOR MASTER SWITCH ASSY

      Tester Connection Specified Condition
      P22-2 (GND) - Body ground Below 1 Ω
