Quick answer
If your airbag warning lamp is on after you've worked on the hub or wheel, stop driving and use a licensed SRS workshop. Don't probe airbag connectors. Refit only with the factory alignment marks and the published torque.
Problem
- Your airbag and SRS parts can only be handled by a qualified workshop.
Symptoms
- Your airbag warning lamp is on after wheel or hub work.
Cause
- Clock spring over-rotation, connector damage or the wrong hub stack height can disturb your SRS circuits.
Fix Step-by-step
- Collect identity before you order: your VIN, build month and clear photos of the current hub and airbag clip style, with no powered probing. We match your kit to SRS generation, spline and stack height, not PCD alone.
- Stack-height budget: measure your OEM hub, approved adapter and wheel. Keep your total inside the clock-spring and airbag clearance in the supplier note. Common mistake: stacking spacers from mixed kits to make it fit.
- Dry-fit splines: you should be able to slide the wheel onto the hub by hand. If you're reaching for a hammer, the spline count or centre bore is wrong, so stop.
- Plan SRS-safe service: you'll find the battery disconnect and airbag handling steps in the OEM manual. Follow them before the wheel lifts off.
- Photograph alignment references: shoot the straight-ahead hub marks and the clock-spring timing dots or tabs before the wheel clears the column.
- If the airbag lamp is on: don't drive it for one more test, use a licensed SRS workshop. Never back-probe airbag connectors with a meter.
Ordering mistakes we see often
- A wrong-generation hub because the wheel looked the same online.
- An aftermarket cruise stalk or horn pad depth changed without re-checking clock-spring compression.
