- 1 min read
CUSTOMER CONCERN
Vehicle will not enter ready mode after an oil change and repeated attempts to reset the maintenance reminder; the combination meter illuminates but the brake warning remains on.
CAUSE
The 12-volt battery discharged below the level needed to power the hybrid control system during the extended reminder-reset attempts.
CORRECTION
Remove and replace the failed 12-volt battery and verify the Prius enters ready mode and the maintenance reminder resets normally.
