Indiana Jones and the Emergency Frunk Release

[louibluey]

I do not remember the details, but there is a scene in Indiana Jones where someone is going to engage him in sword fight (or, something like that), and he says ah hell, and pulls his pistol and shoots the attacker. Well that is the situation with the alternate electrical bumper frunk release.

At the motor release, driver's side close to the front, the geared motor assembly just intercepts the steel wire and pulls it with a little motor and gear box. About the time I was looking at the fuse box (very complicated affair, more in another thread), I realized what about a little pull cord?

Ran a heavy string from the lever arm on the motor latch release out a small existing hole in the charge door. Closed and locked the frunk. Pulled twice, no problem, the frunk easily unlocked!

Not sure on the exact path until I start to bolt and snap the frunk bin and all of those covers back in.

Okay, it all buttoned up fine. On the right side, there is a pass through hole (metal, body color) probably from some not implemented cable (maybe a frunk E-release!), so you can just run through that guide. Watch not getting caught, or putting pressure on the washer spout. The pull loop tucks in fine behind the hinge in the door. The through hole is tiny (use a fish wire to initially get the cord through there), so there is no much danger of the knotted loop falling back in. Avoid the urge to wrap the cord vertically around the door hinge. It might go under pressure when the door is closed and release the frunk latch or damage that plastic lever arm. For those concerned about security, you can push the string all the way back into the hinge port to where it is not even visible, but still be able to fish it out with fingers.

The Double Pull String mod. Live it!

Did you happen to try unlocking any of the doors while the battery was disconnected?

I am guessing they didn't function from the exterior but might have worked from then interior latch releases....

Something to try later, did not. There was talk of the door lock having a super capacitor for an open chance if LVB is dead? Easy enough to see if it still opens after LVB ground disconnected, will try next time the panels are off.

As carful as I was, I did manage to loose one of those sliding head plastic fasteners. I need to buy some of those to replace one someday. I thought they were sliding to give wide tolerance on hole placement, but I wonder if Ford considered them one time use? Anyway they seemed to pop back in okay.

Yes, Darren Palmer had described the super capacitors a while ago. But the early deliveries that were hit by the dead LVB issue were not able to get the doors to open when the LVB was dead, so it would seem that they may not have made it to production.

Here you go.

there's a famous story about this scene, which is that Harrison Ford had dysentery, so on set he just said "screw it I have a gun":

Funny stories? We were shooting in Tunisia, and the script had a scene in which I fight a swordsman, an expert swordsman, it was meant to be the ultimate duel between sword and whip. And I was suffering from dysentery, really, found it inconvenient to be out of my trailer for more than 10 minutes at a time. We'd done a brief rehearsal of the scene the night before we were meant to shoot it, and both Steve and I realized it would take 2 or 3 days to shoot this. And it was the last thing we were meant to shoot in Tunisia before we left to shoot in England. And the scene before this in the film included a whip fight against 5 bad guys that were trying to kidnap Marian, so I thought it was a bit redundant. I was puzzling how to get out of this 3 days of shooting, so when I got to set I proposed to Steven that we just shoot the son a bitch and Steve said "I was thinking that as well." So he drew his sword, the poor guy was a wonderful British stuntman who had practiced his sword skills for months in order to do this job, and was quite surprised by the idea that we would dispatch him in 5 minutes. But he flourished his sword, I pulled out my gun and shot him, and then we went back to England.​

They are in there.
I don't see how they could work from the exterior button though. With no power, how does the vehicle know that a valid FOB, PaaK or pillar code was entered?

I think they only function from inside the car. My car is stuck at the dealership though so I can't test this for myself yet...

I guess it wouldn’t, so security would have to go by the wayside. Kinda like how anyone can get into the frunk when the LVB is dead. Why would the capacitors be needed for opening the doors from the inside when they have a mechanical backup? I’ve read that the back doors don’t have the mechanical backup, but it seems like adding the same cable pull that the fronts have would be easier than adding capacitors.

All great questions. Would like to know the answers myself. I have looked at the parts diagrams and I don't see any separate component for the "super capacitors". I do see "door latch modules" at all four doors so they appear to be the same. I don't see any mechanical latch mechanism or rod/lever etc.

There is a note that says the latch modules store enough power to open for about 3 days or up to 75 operations. That doesn't sound like an emergency exit design to me. Sounds like external entry but then how does the car know to unlatch? So maybe there is enough energy stored to allow that button to work? But if so, then anyone can walk up and pop the doors.

Something doesn't add up in my book......

Interesting, but yes, I'd be concerned about someone finding this and getting the frunk open. It's sort of a "Security by obscurity" situation where you can hide it, which makes it unlikely someone would know it's there, but I still would be nervous about it.
I'd rather hide a 9v in the front bumper compartment (has anyone yet proven this method to work!?), which would only actually do anything if the battery were dead.

Nevertheless, great work. Clever!

I looked it up again because I was curious.
It sure looks like each latch has some sort of cable. I presume these are for the interior release handles. They are on the front and rear doors.

There also is some language about the latch modules....


Each door latch control module has an internal power backup, allowing the door latch release to function for approximately 20 activations or 72 hours after, a power loss (such as a disconnected or depleted battery).

This certainly makes it sound like the exterior buttons should work to open the doors when the LVB is dead. This doesn't answer the question about security though or explain why this didn't work for those that have already had a dead LVB. This is going to take some testing for sure.

When I read that, it sounds like the door would open from the inside in the event of a power failure, not necessarily the outside. It would be nice to have some clarification on that.

But there's mechanical linkages for opening the doors from the inside, so there would be no reason to rely on power for that.
