Why not just push in the clutch, while leaving the trans in reverse? I do it all the time.I would also like to know because I reverse down a long straight downhill driveway. I only need to be in reverse gear for maybe 10-20 feet, and then I kick it into neutral (6MT) and roll. That allows me to go a bit slower and all I have to do is cover the brake for when I reach the road. But as soon as I go into neutral the camera CUTS OUT. The camera should turn on if the car is moving backwards... that should be easy to sense because... the wheels are rolling the "wrong way"... so turn on the darn camera!
I found this in another thread. " Hold Audio+Brightness+Menu for 4 seconds." It was said that this gets you into diagnostics mode on the 10thgen civic.
Thanks for this! Also, bumping this thread: do we know of any way to accomplish this other than the diagnostic menu? I use the rear cameras often simply to check to see if I have pulled enough into a parking space. Not having to do the above or shift into reverse to do this would be great.
The headunit has a wire coming into it that gets +12V when you put the car in reverse so it knows to turn on the backup cam. It would be pretty easy to tap another wire into that wire and run it to a toggle switch that would let you turn on the rear cam whenever you want.
That was anticlimactic. I expected his tranny to grind itself to dust.
Do you know which one it is? I couldn't figure it out from any of the posted pinouts so I ended up running a wire to my rear tail light for my new head unit.
I found it when I saw this bit in the service manual on diagnosing the problem if your HU isn't switching to the backup cam video when you go into reverse:
