  3. CHECK WINDOW GLASS SLIDING MOVEMENT (APPLICABLE LOCATION) Remove the window regulator. Install the window glass onto the door glass run. Check if the door window regulator operates smoothly. Check that the window glass slides smoothly when sliding it up by hand. OK Door window glass slides smoothly. Result Result Proceed to NG A OK (Driver door power window) B OK (Front passenger side power window) C OK (Rear LH side power window) D OK (Rear RH side power window) E HINT: Ensure the following: The window glass fits with the glass run without improper contact or deformation. Foreign objects are not caught in the glass run. WARNING: Perform initialization again. E --> See step 7 D --> See step 6 C --> See step 5 B --> See step 4 A --> FIT WINDOW GLASS CORRECTLY (REMOVE FOREIGN OBJECTS CAUSING IMPROPER FIT OR REPLACE PARTS)
  4. REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY (for Driver Side). Refer to «REMOVAL»(ref-398306-S23446025772011051600000)
  5. REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY (for Front Passenger Side). Refer to «REMOVAL»(ref-398306-S23446025772011051600000)
  6. REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY (for Rear LH Side). Refer to «REMOVAL»(ref-398306-S05137991222011051600000)
  7. REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY (for Rear RH Side). Refer to «REMOVAL»(ref-398306-S05137991222011051600000)
  1. PERFORM INITIALIZATION (APPLICABLE LOCATION) Initialize the power window regulator motor assembly (applicable location). Refer to «INITIALIZATION»(ref-398104-S26144902002011051600000) . NEXT: Go to next step
  2. CHECK POWER WINDOW CONTROL SYSTEM (AUTO UP/DOWN FUNCTION) Check if the power window auto up and down functions operate normally. Refer to «OPERATION CHECK»(ref-398104-S28512148702011051600000) . OK Auto up and down functions are normal. NG --> See step 4 OK: Go to next step
  3. CHECK JAM PROTECTION FUNCTION OPERATING RANGE Check if the jam protection function operates normally for the applicable power window. HINT: The jam protection function will not operate within 4 mm (0.157 in.) of the fully closed position. OK Jam protection function operates normally. Result Result Proceed to OK A NG (Driver door power window) B NG (Front passenger side power window) C NG (Rear LH side power window) D NG (Rear RH side power window) E E --> See step 8 D --> See step 7 C --> See step 6 B --> See step 5 A --> END (PROBLEM DUE TO INITIALIZATION FAILURE)
  4. GO TO OTHER PROBLEM (Proceed to Problem Symptoms Table). Refer to «PROBLEM SYMPTOMS TABLE»(ref-398104-S23700997632011051600000)
  5. REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY (for Driver Side). Refer to «REMOVAL»(ref-398306-S23446025772011051600000)
  6. REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY (for Front Passenger Side). Refer to «REMOVAL»(ref-398306-S23446025772011051600000)
  7. REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY (for Rear LH Side). Refer to «REMOVAL»(ref-398306-S05137991222011051600000)
  8. REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY (for Rear RH Side). Refer to «REMOVAL»(ref-398306-S05137991222011051600000)
