Frequently Asked Questions (FAQ)

Which Tesla models and years is this pretensioner compatible with?

DetailsThis pretensioner is designed for Tesla Model 3 and Model Y vehicles that use part numbers 1090322-C1-D (Front Left) or 1090324-C1-D (Front Right). Always verify your vehicle’s exact part number, connector type, and mounting configuration before ordering, as Tesla periodically updates SRS components across production years.

Can I install this pretensioner myself?

DetailsProfessional Installation Recommended. Because this is a safety-critical SRS component, installation by a qualified technician or certified body shop is strongly recommended. After installation, an SRS system diagnostic scan is recommended to confirm correct operation and clear any DTC fault codes.

How do I know if my seat belt pretensioner needs to be replaced?

DetailsCommon signs include an illuminated airbag/SRS warning light on the dashboard, a pretensioner that has already deployed following a collision (deployed units are single-use and must be replaced), or a seat belt that feels loose and does not retract properly. Always have the vehicle diagnosed with a professional scan tool before replacing SRS components.

Is this an OEM or aftermarket part?

DetailsThis is an OEM-grade replacement part engineered to meet the original specifications of the Tesla factory component. It is designed to fit the original mounting points and integrate with the factory SRS system. Always confirm part number compatibility before installation.
