NOTE: Match the arrow mark of the probe with the current direction.

(2) Set the door glass to the fully closed position.
(3) When 60 seconds have elapsed after the door glass is fully closed, pull the power window switch up once again. Check how long it takes for the current to change from approximately 16 to 34 A into 1 A or less.

Approximately 4 to 90 seconds
