    I need to transport some long pieces of wood and would like to disable the open hatch warning beeping. Is this something I can do with Carista and the OBD2 device?

    Or fool the hatch into thinking it's closed? You put a screwdriver or similar into the latch below, mimic the tang on the hatch? I read somewhere about that, on a 2nd or 3rd gen, might be worth trying.

    Now why didn't I think of that! Sounds like that would work. Thanks!

    If the latch is recessed maybe a padlock or carabiner hasp would work good. Or a U-bolt.

    I used a bolt, with a similar diameter to the lower locking mechanism. I just pushed the bolt up into the latch and it locked onto the bolt, turning off the warning beep. To release, you just press the "open door" handle on the hatch, and it lets go of the bolt.

    I got fancy when I loaded up the 12 foot lumber I picked up today, and instead of a bolt, I pushed the end of a bungee into the mechanism. There is no place to hook a bungee onto the hatch, to hold it down. Now there is. Worked out great, and I got the lumber home without the annoying beeping, and with the hatch held down securely.

    I guess a carabiner could serve similar purpose: snap in the latch, then run a rope or bungee cord through. I'm a little leery of bungee cords: if there's wind uplift on the load it might overpower the cord's tension start to lift the load. Plus if they let loose they can be nasty.

    About 35 years ago my brother-in-law gave me a tip: make a little lasso in your cord, either at the end or along it's length, then run the cord end through the loop and cinch it, get's it super-tight.

    Yes, I use that technique all the time, but not on the hatch.

    BTW, I have a nice lower point to attach whatever I use, since I installed a hitch. Either side of the receiver has the safety chain loops, which make a nice place to attach the bungee (or rope).

    Bare fingers and thumbs work OK, at least on the 3rd generation. Or any U- or L-shaped rod of suitable diameter, including some kinky screwdrivers. I do this whenever I need to leave the hatch open or unlatched without abusing the battery.
