Inspection Procedure

CHECK DIAGNOSTIC CODE OUTPUT
1. Check the diagnostic code.
  HINT:
  
  AUTO illumination starts blinking after the ignition switch is turned ON to OFF and stops in approximately 43 seconds or when the driver's door is once opened then closed (the conditions to operate the window automatically after key-off are satisfied).
  1. Check whether the AUTO illumination for the power window regulator master switch blinks after the ignition switch is turned ON to OFF.
    HINT:
    - NG - A means that blinks in the 1 or 3 way.
    - NG - B means that blinks occurs in the 2 way.

  1. NG:-B Go to step 4 .
  2. OK: REPLACE POWER WINDOW REGULATOR MASTER SWITCH ASSY
  3. NG:-A GO TO NEXT STEP
CHECK POWER WINDOW REGULATOR MASTER SWITCH ASSY
1. Remove the power window regulator master switch (the power window regulator master switch connector is connected).
2. Check the voltage between terminal SGND (2) and terminal LMT (17) of the D12 power window regulator master switch connector when the driver's door glass is not in the fully closed.
  Voltage: 10 - 14 V
