INSPECTION
CAUTION / NOTICE / HINT
NOTICE:
-
Do not apply positive (+) auxiliary battery voltage to any terminals, except terminal K7-2 (B) or L7-2 (B), to avoid damaging the pulse sensor inside the motor.
-
Perform initialization of the power window system after removing, inspecting or replacing the power window regulator motor assembly.

PROCEDURE
1. INSPECT POWER WINDOW REGULATOR MOTOR ASSEMBLY RH
(a) Connect a positive (+) auxiliary battery lead to connector terminal K7-2 (B).
*a | Component without harness connected (Power Window Regulator Motor Assembly RH) | *b | Motor Gear |
| Clockwise |
| Counterclockwise |
NOTICE:
Do not connect a positive (+) auxiliary battery lead to any terminals other than terminal K7-2 (B) to avoid damaging the pulse sensor inside the motor.
(b) Connect a negative (-) auxiliary battery lead to connector terminals K7-1 (GND) and K7-7 (DOWN) or K7-10 (UP).
(c) Check that the motor gear rotates smoothly as follows:
OK:
Measurement Condition | Specified Condition |
-
Connect the positive (+) auxiliary battery lead to terminal K7-2 (B), connect a negative (-) auxiliary battery lead to terminal K7-1 (GND), and keep them connected for 3 seconds or more.
-
With terminals K7-2 (B) and K7-1 (GND) connected, connect a negative (-) auxiliary battery lead to terminal K7-10 (UP).
| Motor gear rotates clockwise |
-
Connect a positive (+) auxiliary battery lead to terminal K7-2 (B), connect a negative (-) auxiliary battery lead to terminal K7-1 (GND), and keep them connected for 3 seconds or more.
-
With terminals K7-2 (B) and K7-1 (GND) connected, connect a negative (-) auxiliary battery lead to terminal K7-7 (DOWN).
| Motor gear rotates counterclockwise |
-
If the result is not as specified, replace the power window regulator motor assembly RH.
2. INSPECT POWER WINDOW REGULATOR MOTOR ASSEMBLY LH
(a) Connect a positive (+) auxiliary battery lead to connector terminal L7-2 (B).
*a | Component without harness connected (Power Window Regulator Motor Assembly LH) | *b | Motor Gear |
| Counterclockwise |
| Clockwise |
NOTICE:
Do not connect a positive (+) auxiliary battery lead to any terminals other than terminal L7-2 (B) to avoid damaging the pulse sensor inside the motor.
(b) Connect a negative (-) auxiliary battery lead to connector terminals L7-1 (GND) and L7-7 (DOWN) or L7-10 (UP).
(c) Check that the motor gear rotates smoothly as follows:
OK:
Measurement Condition | Specified Condition |
-
Connect a positive (+) auxiliary battery lead to terminal L7-2 (B), connect a negative (-) auxiliary battery lead to terminal L7-1 (GND), and keep them connected for 3 seconds or more.
-
With terminals L7-2 (B) and L7-1 (GND) connected, connect a negative (-) auxiliary battery lead to terminal L7-10 (UP).
| Motor gear rotates counterclockwise |
-
Connect a positive (+) auxiliary battery lead to terminal L7-2 (B), connect a negative (-) auxiliary battery lead to terminal L7-1 (GND), and keep them connected for 3 seconds or more.
-
With terminals L7-2 (B) and L7-1 (GND) connected, connect a negative (-) auxiliary battery lead to terminal L7-7 (DOWN).
| Motor gear rotates clockwise |
-
If the result is not as specified, replace the power window regulator motor assembly LH.

The front seat belt pretensioners are designed to deploy in moderate or
severe frontal, near frontal collisions.
In addition, the pretensioners operate when a side collision or a rollover
accident is detected. The pretensioners operate differently
depending on what types of air bags are equipped. For more details
about the seat belt pretensioner operation, refer to the SRS Air Bag
Deployment Criteria.
