PRE-CHECK




1. CHECK WINDOW LOCK SWITCH
a. Check that operation of the door glasses except for the driver side door glass, the back door glass and the roof glass is disabled when the window lock switch of the power window master switch is pressed.
b. Check that the door glasses, the back door glass and the roof glass can be operated when the window lock switch is pressed again.




2. CHECK MANUAL UP/DOWN FUNCTION
Check that the back door glass can be operated using the back power window switch as shown.




3. CHECK AUTO UP/DOWN FUNCTION
Check that the back door glass can be operated using the back power window switch as shown.




4. CHECK MANUAL UP/DOWN FUNCTION VIA BACK DOOR LOCK KEY CYLINDER
Check that the back door glass operates when the back door lock key cylinder is operated using the key as shown.

5. CHECK MANUAL DOWN FUNCTION VIA TRANSMITTER
Check that the back door glass keeps opening while the back door power window switch on the transmitter is pressed with the rear wiper in the retract position.

6. CHECK POWER WINDOW OPERATION FUNCTION AFTER IGNITION OFF
Under both of the following conditions, check that the door glasses, the back door glass and the roof glass can be operated even after the ignition switch is turned OFF:
- Within 45 seconds after the ignition switch is turned OFF
- The driver side door is closed

7. CHECK JAM PROTECTION FUNCTION

HINT: The jam protection function prevents any part of your body from getting caught by accident between the door frame and the door glass during power window operation.

Check that the door glass goes down by 50 mm (2.0 in.) right when something gets caught between the door frame 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 operation after ignition OFF
- MANUAL UP via the back door lock key cylinder

8. CHECK FAIL-SAFE FUNCTION
If the pulse sensor in the back door power window motor malfunctions (DTC B2221 is output), the power window functions will be restricted:
- The AUTO UP/DOWN function is disabled.
- The MANUAL DOWN function via the transmitter is disabled.
- The MANUAL UP/DOWN function via the back door power window switch can be performed (the ignition switch ON).
- The MANUAL UP/DOWN function via the back door lock key cylinder can be performed (the ignition switch ON).




9. CHECK DATA LIST WITH HAND-HELD TESTER
According to the data list displayed by the hand-held tester, you can read the value of the switch, sensor, actuator without parts removal. Reading the data list as a first step of troubleshooting is one of the method to shorten the labor time.

10. USING HAND-HELD TESTER, CHECK SWITCH CONDITION BY DTC
DTC B1241 is output when the back door power window switch, the defogger switch and the rear power window switch are on. When these switches are off, this DTC is not output.
Using this DTC, you can check whether these switches are normal or not.




11. PERFORM ACTIVE TEST WITH HAND-HELD TESTER
The active test will indicate if the part is normal or malfunctioning.
