Inspection Procedure

1. Check that the DTC B1221 is output when power window master switch is operated.

HINT:

• If B1221 is output when the switch is not operated, it is detected the switch sticking.
• If B1221 is not output when switch is operated, it is detected that the switch contact condition is bad.

1. NG: GO TO FLOW CHART (See  DTC B1221 POWER WINDOW SWITCH CIRCUIT ON DRIVER DOOR  ) 
2. OK: GO TO NEXT STEP 

1. Check the power window master switch condition by the data monitor.

   Standard: (Driver door ECU)

2. Set the electrical tester and DC400A probe to the wire harness of terminal 1 or 4.

   SST 09083-00350

3. Close the door glass fully.
4. Inspection of current cut-off:

   When approximately 60 seconds has elapsed after the door glass fully closed, check the changing time of the current, from 16 - 34 A into 1 A, when the power window regulator switch turned UP once again.

   Standard: Approximately 4-90 seconds 

5. When approximately 60 seconds has elapsed after the inspection of the current cut-off, check that the door glass goes down when the power window regulator switch turned DOWN.
