WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 Honda Odyssey, 2016 Honda Odyssey, 2015 Honda Odyssey, 2014 Honda Odyssey, and 2013 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.
The climate control unit receives its power supply from the battery all the time to memorize the state of the cool box before turning the ignition switch to LOCK (0) and reproduce the same state when turning the ignition switch to ON (II) within one hour.
