High Beams
WARNING: This page is about a different car, the 2013 Honda Fit, 2012 Honda Fit, 2011 Honda Fit, 2010 Honda Fit, and 2009 Honda Fit. However, it is still accessible from the selected car via links, so may be relevant.
When you turn the headlight switch to the ON position and the dimmer/flash-to-pass switch to the high position, ground signals are supplied to under-dash fuse/relay box connector M (34P) terminals No. 3 and No. 5. The MICU then energizes the high beam headlight control circuits, supplying battery voltage to the high beam headlights, turning them on.
