2. Check PTC operation:
   NOTE: The work must be performed with the power window regulator and door glass installed on the vehicle.
   1. Install the power window regulator motor (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 pressing the power window UP switch. Wait for approximately 60 seconds.
   4. Continue to press the power window UP 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 (Inspection of current shut-off).

      Standard: 4 to 90 seconds 

   5. 60 seconds after the previous step, press the power window DOWN switch (rear LH side).

      OK: The rear LH side window goes down. 

NG: REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY (REAR LH)  (See REMOVAL  )

OK: Go to next step. 

1. Disconnect the M1 and K2 connectors.
2. Measure the resistance according to the value(s) in the table below.

   Standard resistance
