What can cause airbag or srs warning?
Airbag or SRS warning can come from more than one safety & restraints branch. Operating conditions, warning behavior, scan data, and physical tests are needed to separate the supported cause from look-alikes.
Plausible causes
- Restraint or driver-assistance system concern
- Temporary sensor limitation
- Calibration, mounting, alignment, power, or network fault
Useful next checks
- Record the exact message, feature, warning versus brake/steering action, weather, road markings, and recent glass, bumper, collision, tire, ride-height, or alignment work. Clean only owner-manual-approved external sensor surfaces.
- Full restraint/ADAS/body scan plus 12-volt and network checks
- Glass, bracket, radar/camera mount, bumper, and sensor inspection
