SRS

📖 YOUCANIC Automotive Glossary

SRS (Supplemental Restraint System) is the complete occupant protection system including all airbags (front, side, curtain, knee, rear), seatbelt pretensioners, crash sensors, the airbag control module, clock spring, and occupant detection system. The SRS warning light on the dashboard indicates a system fault and airbags may not deploy in a crash — this should never be ignored as it directly affects occupant safety.

Common SRS DTCs include B-codes for circuit faults — clock spring failures, seat belt buckle switch faults, side impact sensor wiring issues, and stored crash data from previous collisions. The YOUCANIC UCAN-II reads SRS-specific codes that basic code readers cannot access, performs crash data clearing after collision repair, and supports ODS initialization. After any collision repair, SRS system scanning is mandatory. Never ignore the SRS warning light — it means a critical safety system is disabled.
