Obstruction Detection Function
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.
If any obstruction is detected while the tailgate is automatically opening or closing, the tailgate will stop and reverses its operation. An obstruction is detected by the tailgate pinch sensor and the pulser in the drive unit. If the obstruction is detected when the shift lever is in any position other than P, or the vehicle speed exceeds 1 mph (2 km/h), the tailgate stops moving immediately.
