What it means
The onboard accelerometer (used for tip-over / lean sensing) failed its power-on self-test and is retrying. Logged as 'Accelerometer Selftest Failed, retrying...'.
Informational — Normal operation events, no action required.
Likely causes
- Transient sensor glitch at power-up
- A single missed self-test that passes on retry
- Rarely, a failing accelerometer that never passes
What to do
- 1Usually clears on retry — no action needed
- 2Note it only if it fails on every boot
- 3If it never passes, have tip-over detection checked at service
