Seatbelt Buckle - Inflatable Seatbelt
WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
The seatbelt buckle incorporates an inflator that is filled with inert gas under pressure and a pyrotechnic device to release the gas. The inflator is serviced with the seatbelt buckle as an assembly.
On vehicles equipped with inflatable seatbelts, the seatbelt buckle and inflator has 3 functions:
- Receives the tongue and holds it in place until the release button is pressed.
- Senses if the inflatable seatbelt is buckled using a Hall-effect sensor which is hard-wired to the RCM.
- Directs the gas from the seatbelt inflator into the inflatable seatbelt.
For seatbelt buckle and inflator location information: Refer to Airbag and Seatbelt Pretensioner Supplemental Restraint System (SRS) - Component Location
To diagnose any seatbelt buckle or inflator Diagnostic Trouble Codes (DTCs), Refer to AIRBAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
