## INSPECTION PROCEDURE

1.INSPECT POWER WINDOW REGULATOR MOTOR ASSEMBLY (DRIVER SIDE)

1. LHD:

   1. Remove the motor.

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

      NOTICE:

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

      OK:

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

1. RHD:

   1. Remove the motor.

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

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

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

      OK:

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

        Always (ON / OFF) | DOWN | 2 (DU) - 10 (E) 5 (DD) - 9 (B) | Below 1 Ω
        Always (ON / OFF) | AUTO DOWN | 2 (DU) - 10 (E) 5 (DD) - 9 (B) | Below 1 Ω

1. LHD (Double cab):
   Inspect the driver switch.

   1. Remove the master switch.

   2. Measure the resistance of the switch when the switch is operated.

      Standard resistance:
