1. Install the power window regulator motor assembly (rear LH side) (See INSTALLATION ).
2. Connect an electrical tester DC 400 A probe to the wire harness of terminal 1.
   NOTE: Match the arrow mark of the probe with the direction of the current flow.
3. Fully close the door glass by pulling up the power window switch. Wait for approximately 60 seconds.
4. Continue to pull up the power window switch and measure how long it takes for the electrical current to change from a range of 16 to 28 A to approximately 1 A (current shut-off inspection).

   Standard: 4 to 90 seconds 

5. Wait for 60 seconds after the previous step, and then push down the power window switch (rear LH side).

   OK: The rear LH side window goes down  .
