Record by record
4 records state a cause or a remedy. Each record is shown as short labels in the order fault → finding the cause → correction. Press a label to narrow to the records that state it.
Symptom
Component named as the cause
Work done
A ribbon is as wide as the records that state both of its ends (only the commonest are drawn). A record that names several symptoms or components runs through each. Orange is records that say the fault came back or was not fixed. Results come from owners’ reports only; one that does not say is “result not stated”. None of this is a likelihood of a cause or a rate at which work succeeds.

Technical Bulletin 05-09-40-002F Notification
1Fault
- Overspool lock: if the webbing snaps back to the stowed position rapidly enough, the retractor locks with the belt fully stowed.
- Vehicle-sensing lock occurs when the vehicle changes speed or direction abruptly: rapid acceleration, rapid deceleration or aggressive cornering.
- It can also occur with the vehicle static, parked on a large slant, fore-aft or side-to-side.
- Web-sensing lock: when the webbing reels out at an accelerated rate it goes into lock mode and stays there until tension is released.
- Pulling the webbing all the way out automatically converts the retractor into a cinch-down mode (ALR), typically used to secure a child seat tightly.
2Finding the cause
Possible causes
- With the webbing fully loaded on the spool the retractor cannot rewind further to release the locking mechanism, so the occupant cannot extract the belt.
3Correction
Repair
- Pull hard on the locked webbing and then release; the hard pull extracts a small amount of webbing, which permits a small amount of retraction when released.
- The ALR mode is cancelled automatically when the belt is unfastened and stowed.
Caution
- Do not replace the retractor for this condition before first trying to disengage the locking mechanism as recommended.
- A belt that the customer says locks intermittently in these conditions is working as designed and functioning properly.
