Also called: airbag, SRS
What it means
Supplemental restraint system fault — airbags or pretensioners may not fire.
What to do first: Book diagnosis soon. Do not ignore before MOT — illuminated SRS lamps often fail.
Common causes
- A genuine airbag / srs system fault
- A failed sensor or switch reporting a false warning
- Low voltage after a weak 12V battery (can set multiple lamps)
- Recent work (battery change, wheels, sensors) that needs a reset or calibration
Step-by-step
- 1Book diagnosis soon. Do not ignore before MOT — illuminated SRS lamps often fail.
- 2Photograph the light and any message-centre text for the garage or breakdown operator.
- 3Note whether the car feels normal — power loss, smoke, smells or strange noises change the priority.
- 4Avoid clearing codes repeatedly without fixing the cause; the fault will return and can fail an MOT.
MOT note
Safety and emissions warning lamps that stay on are commonly checked at MOT — fix before the test if required.
