After any collision, the airbag and SRS system is one of the most critical components that must be correctly diagnosed, repaired and documented before a vehicle returns to the road. A faulty or incorrectly repaired SRS system can mean airbags that don't deploy when needed — or worse, deploy unexpectedly. At National Auto-Tec, we provide comprehensive airbag, SRS and crash data services across Melbourne — trusted by panel shops, smash repairers, insurance companies and private customers.

Our mobile service comes directly to your workshop or location, with all work completed to OEM manufacturer specifications and fully documented for insurance purposes.

Crash Data Resets After a collision where airbags have deployed, the airbag control module stores crash data that must be cleared before the system can function again. We perform professional crash data resets — restoring the SRS module to pre-accident condition and verifying full system functionality after reset. All work is documented with insurer ready reports.

Airbag Module Repair & Replacement When crash data cannot be cleared or the airbag module is physically damaged, replacement is required. We supply, replace and program airbag control modules to OEM specifications — ensuring correct coding and full system integration after replacement.

Seatbelt Pretensioner Replacement & Coding Seatbelt pretensioners fire during a collision and must be replaced afterward — they cannot be reused. We supply and replace pretensioners across all vehicle makes and models, coding the new units correctly to the SRS system.

Seatbelt Retractor & Buckle Replacement Damaged or locked seatbelt retractors and buckles are replaced and coded as part of a complete SRS system restoration — ensuring every component of the safety system is functioning correctly.

Clockspring Replacement & Coding The clockspring is a critical SRS component connecting the airbag in the steering wheel to the vehicle's electrical system. Damage or wear results in airbag warning lights and potential SRS faults. We supply, replace and code clocksprings across all major vehicle makes and models.

Airbag Impact Sensor Replacement & Coding Airbag impact sensors detect collision forces and trigger airbag deployment. After a collision these sensors frequently require replacement and coding — we supply and fit all sensor types with correct OEM coding.

Side Curtain, Knee & Seat Airbag Services Modern vehicles contain multiple airbag units throughout the cabin. We diagnose, repair and replace side curtain airbags, knee airbags and seat mounted airbags — restoring full SRS system coverage after collision damage.

SRS Wiring Diagnosis & Repair SRS wiring is yellow coded throughout the vehicle for safety reasons. Damage to SRS wiring requires specialist diagnosis and repair — we carry out all SRS wiring repairs to manufacturer safety specifications.

Full SRS System Diagnostic Report Every job includes a comprehensive SRS diagnostic report documenting pre-repair condition, work completed and post-repair system verification. Our reports are accepted by all major insurers and provide panel shops with the documentation they need to close jobs.
