Inspection Procedure

CHECK DTC OUTPUT
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 (See FLOW CHART )
2. OK: Go to next step.
READ VALUE OF HAND-HELD TESTER
1. Check the power window master switch condition by the data monitor.

2. NG: Go to next step.
CHECK POWER WINDOW REGULATOR MOTOR ASSY LH
NOTE:
- Be sure not to apply the battery voltage to terminal 2, 5 and 6 of the power window regulator motor assembly LH connector, because it might damage the pulse sensor and the limit switch.
- Be sure to reset the power window regulator motor assembly (Initial position setting of the limit switch) when the power window regulator motor assembly LH is Installed to the regulator.
- Work must be done with the power window regulator and door glass installed to the vehicle.
1. Check that the motor operates smoothly when the battery voltage is applied to each terminal of the connector.

2. Set the electrical tester and DC400A probe to the wire harness of terminal 1 or 4.
  SST 09082-00040, 09083-00350
3. Close the door glass fully.
4. Inspection of current cut-off:
  When approximately 60 seconds has elapsed after 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.
1. NG: REPLACE POWER WINDOW REGULATOR MOTOR ASSY LH
2. OK: Go to next step.
CHECK WIRE HARNESS (POWER WINDOW MOTOR LH - ECU)
1. Disconnect the motor and D19 ECU connectors.
