Frequently Asked Questions
How do I know if the pretensioner has already fired?
A deployed pretensioner will show signs of firing -- the seatbelt may not fully retract and the pretensioner unit will appear spent. A technician can visually inspect it.
Is this code serious?
Yes. The seatbelt pretensioner is a critical part of the vehicle's occupant restraint system and works together with airbags to protect you in a crash.
Can water cause pretensioner issues?
Yes. Water leaking into the B-pillar area from door seals or body seams can corrode the pretensioner connector and wiring.
