INSPECTION PROCEDURE

1. Remove the power window master switch (COROLLA_ZRE142 RM000002AC90CLX.html).
   

2. Measure the resistance according to the value(s) in the table below.
   

   Standard Resistance:

   Tester Connection	Switch Condition	Specified Condition
   1 (E) - 4 (D) 3 (U) - 6 (B)	UP	Below 1 Ω
   1 (E) - 3 (U) 1 (E) - 4 (D)	OFF	Below 1 Ω
   1 (E) - 3 (U) 6 (B) - 4 (D)	DOWN	Below 1 Ω
   1 (E) - 3 (U) 6 (B) - 4 (D)	AUTO DOWN	Below 1 Ω

1. Disconnect the power window regulator motor assembly (driver side) motor connector.
   

2. Measure the resistance according to the value(s) in the table below.
   

   Standard Resistance:

   Tester Connection	Condition	Specified Condition
   I3-4 (D) - I7-1 (D)	Always	Below 1 Ω
   I3-3 (U) - I7-2 (U)	Always	Below 1 Ω
   I3-4 (D) - Body ground	Always	10 kΩ or higher
   I3-3 (U) - Body ground	Always	10 kΩ or higher

1. Remove the power window regulator motor assembly (COROLLA_ZRE142 RM000002YF201SX.html).
   

2. Check power window regulator motor operation:
   

   1. Apply battery voltage to connector terminals 1 and 2.
      

      NOTICE:

      Do not apply battery voltage to any terminals except terminals 1 and 2.

   2. Check that the motor gear rotates smoothly as follows.
      

      OK:

      Measurement Condition	Specified Condition
      Battery positive (+) → 1 (D) Battery negative (-) → 2 (U)	Motor gear rotates counterclockwise
      Battery positive (+) → 2 (U) Battery negative (-) → 1 (D)	Motor gear rotates clockwise

3. Check PTC operation:
   

   NOTICE:

   This check must be performed with the power window regulator and door glass installed on the vehicle.

   1. Install the power window regulator motor (COROLLA_ZRE142 RM000002YF001UX.html).
      

   
   
   

   2. Connect an electrical tester DC 400 A probe to the wire harness of terminal 2.
      

      NOTICE:

      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 press the power window switch (driver side).
      

      OK:

      The driver side window goes down.
