Seat Belt Retractor: Testing and Inspection

RETRACTOR INSPECTION
Seat belts and attaching parts can affect the vital components and systems of a vehicle. Therefore, they should be inspected carefully and replaced with genuine parts only.


Seat Belt Strap Switch (Driver Side)
Check driver side seat belt strap switch for continuity by using ohmmeter.

Without inserted buckle tongue to buckle catch:
Terminal "A" and "B" = Continuity

With inserted buckle tongue to buckle catch:
Terminal "A" and "B" = No continuity

Automatic Locking Retractor (ALR)
Seat belts with ALR (other than driver side seat belt), check them as follows in addition to above check.

- With vehicle at stop, pull seat belt all the way out, let it retract a little and try to pull it. It should not be pulled out, that is, it should be locked where retracted.
- Let seat belt retract to its original state. Next, pull it half way out, let it retract a little and try to pull it again. It should be pulled out smoothly, that is it should not be locked at this time.

- Let the seat belt retract fully to confirm its easy retraction.
- The retractor assembly should lock webbing when pulled quickly.
- The retractor assembly should lock webbing even when tilted (approx. 15°) toward the fore and aft or right and left directions.
