Power Window Control System: Inspection

INSPECT DIAGNOSIS CODE IS OUTPUT
Check that the master switch assembly automatic light flash under the condition of KEY off operation (for 45 secs. after the starter switch has been turned from ON to OFF with the driver's door open.)

HINT:
- Limit switch malfunction:
  Even though the glass goes down from the fully closed position, the power window regulator switch assembly does not detect a change in limit switch signal within 2.0 secs. after the operation has started.
- Pulse sensor malfunction:
  Even though the glass goes down from the fully closed position, the power window regulator switch assembly does not detect a change in pulse switch signal within 2.0 secs. after the operation has started.

3. Continue to apply voltage, check that there is a PTC operation noise within approximately 4 to 90 seconds.
4. Reverse the polarity, check that the window begins to descend within approximately 60 seconds.
If operation is not as specified, replace the motor.
INSPECT JAM PROTECTION FUNCTION
NOTE: Never, ever be caught any part of your body when checking.

HINT:

In case of performing resetting of the limit switch, do checking after repeating up and down of the glass with automatic operation.
1. Confirmation of AUTO up operation:
  Confirm that the window will be fully close with AUTO up operation.
2. Checking of the operation of the jam protection function:
  1. Move up the window with AUTO up operation and check that the window will go down when it touches the handle of the hammer stetted.
  2. Confirm that the window will then stop going down about 200 mm.
HINT:

In case of removing the glass, glass guide, regulator and etc. be sure to perform checking of the jam protection function. If the jam protection is not functioned properly, adjust power window motor reset switch and pulse switch.
