you will see all parking sensor
indicators on the instrument panel,
and a beeper sounds continuously.
2011 Odyssey
If there is a problem with any of the
operational sensors, the indicators
for these sensors will appear
constantly in red.
Very often, a sensor covered with
mud, ice, snow, etc. is the cause of
this display. Check the sensors first.
If the indicators stay on or the
beeper does not stop, have the
system checked by your dealer.
