closed position using the power window switch and
measure the time until the electrical current
changes into 1 A from 16 to 34 A (Inspection of cur-
rent shut±off).
Standard: Less than 1 second

(b) Operate the power window using the master (regulator) switch.
(c) Disconnect the battery, fuse or motor connector while the power window is operating, so that t\
he power window motor is forced to stop.
(d) Reconnect the battery, fuse or motor connector.
(e) Pull up the power window switch until the power window is fully closed and h\
old the switch at least 1 second.
(f) Check that the AUTO UP/DOWN function operates completely.
