Title: WINDOW / GLASS: POWER WINDOW REGULATOR MOTOR (for Rear Door): INSPECTION (2008 LX570)

INSPECTION

1. INSPECT REAR POWER WINDOW REGULATOR MOTOR ASSEMBLY LH

(a) Apply positive (+) battery voltage to the connector terminal 2 (B).

NOTICE:

Do not apply positive (+) battery voltage to any terminals except terminal 2 (B) to avoid damaging the pulse sensor inside the motor.

(b) Apply negative (-) battery voltage to the connector terminals 1 (GND) and 7 (DOWN) or 10 (UP).

(c) Check that the motor gear rotates smoothly as follows.

OK:

Measurement Condition

Specified Condition
  1. Connect the positive (+) battery cable to terminal 2 (B), and connect the negative (-) battery cable to terminal 1 (GND), and keep them connected for 3 seconds or more.
  2. With terminals 2 (B) and 1 (GND) connected, connect the negative (-) battery cable to terminal 10 (UP).
  3. Disconnect and reconnect the negative (-) battery cable to terminal 10 (UP) within 1 second.

Motor gear rotates clockwise (Up)
  1. Connect the positive (+) battery cable to terminal 2 (B), and connect the negative (-) battery cable to terminal 1 (GND), and keep them connected for 3 seconds or more.
  2. With terminals 2 (B) and 1 (GND) connected, connect the negative (-) battery cable to terminal 7 (DOWN).
  3. Disconnect and reconnect the negative (-) battery cable to terminal 7 (DOWN) within 1 second.

Motor gear rotates counterclockwise (Down)

If the result is not as specified, replace the power window regulator motor assembly.

CAUTION:

Reset the power window regulator motor (initialize the pulse sensor) after installing the power window regulator motor and regulator assembly onto the door.
