7. CHECK JAM PROTECTION FUNCTION
HINT: The jam protection function prevents any part of your body from getting caught by accident between the door flame and the door glass during power window operation.
a. Check that the door glass goes down by 50 mm (2.0 in.) right when something gets caught between the door flame and door glass during power window operation. However, when the opening amount between the vehicle body and the door glass is less than 200 mm (7.9 in.), the door glass keeps going down until the opening amount reaches 200 mm (7.9 in.) and stops there.
Operative condition:
- AUTO UP via the back door power window switch
- AUTO/MANUAL UP during power window operation after ignition OFF
- MANUAL UP via the back door lock key cylinder
8. CHECK FAIL-SAFE FUNCTION
a. It the pulse sensor in the back door power window motor malfunctions (DTC B2221 is output), the power window functions will be disabled:
