What it can mean
A solid light usually indicates pressure; a flashing-then-solid pattern often indicates a monitoring-system fault.
What to do next
- Slow down and inspect for visible tire damage.
- Measure cold pressure with a gauge and use the door-placard specification.
- Do not use the tire sidewall maximum as the normal target pressure.
Possible causes to test
- Low tire pressure
- Puncture or leak
- Temperature-related pressure change
- TPMS sensor or receiver fault
