Airbag Warning Light (SRS Light)
The airbag warning light shows a fault in the restraint system, which means airbags or seatbelt pretensioners may not deploy in a crash.
What is Airbag Warning Light (SRS Light)?
Frequent causes are the clock spring, seat connectors or the passenger seat occupancy sensor. Disconnecting the battery or moving seats can disturb connectors. Many countries treat a lit airbag light as a defect at the roadworthiness test. Airbag faults are stored as codes in the airbag control unit and need a suitable diagnostic tool to read.
How it works
The airbag control unit tests the circuits at every start and keeps the light on when a resistance or signal is out of range.
Why it matters for your car
Have it diagnosed promptly, because protection in a crash may be reduced. Work on airbag systems should only be done by trained technicians.
