Was replacing the battery on my 2014 V8S F-type - Vert, and had to stop midway. The stupid stick hit me, and I shut the trunk. The cables are disconnected, and I cannot use the front jump points. I have been looking around, and found threads on how techs have been able to open the trunk by applying voltage to the trunk solenoid from the Central Junction Box ( passenger footwell) . Unfortunately, no detailed instructions.

I have looked and gone thru the V6S service manual (see below) to trace the wiring but no luck. Has anyone opened the truck by powering the trunk with CJB - any procedures/pointers. Any help would be greatly appreciated.


Thanks

 

Check out post #6 by Unhingd (the savior, as always, haha).. you should be able to power the trunk with this method.

Not sure if this will help,

 

I keep a small but powerful battery booster in the cabin. Once you have that, you open the door manually with the key, get the booster, open the hood. Connect the booster and "voila"
You can get one of those from amazon shipped next day.

 

But the OP has a problem that your solution won't help with - his battery cables are disconnected from the battery!

 

Thanks all. Little more on the problem - I was trying to remove the dead secondary battery also. While doing so, I had disconnected the positives to the bus bar. With that there is no closed loop to the battery. All bad things at once !!!!! I'm mad at myself and a little bit at Jaguar ( not much though) - they should have added a key unlock option to the trunk. My car is unlocked (except the trunk !!!). Having said that - I'm down to two options.

1. Have the dealer open the trunk by applying 12V to the trunk lid switch. I don't know the magical location on the CJB to do this.
2. Try and see if a locksmith can jimmy it open by pulling on the internal emergency release switch. ( I don't have much faith in this one). I could end up with more damage.

Appreciate all the feedback.

 

Someone went through all this not long ago, but I don’t remember how they ended up getting in the trunk. There’s a thread somewhere...

 

Maybe you could use a cigar lighter type jumper cable. You plug it in the receptacle of a car with a good battery to charge the low battery, You wouldn't try to start the car ,that would fry the circuit, but it might give enough power to open the trunk latch.

 

Good idea. Ordered the CTEK lighter plug in adapter - will be here tomorrow. Fingers crossed. Thanks

 

Read thru most of them. There was one with a work order attached to the post - tech reported opening trunk via CJB (Central Junction Box). Will look again.

 

I thought the OP had disconnected the battery. Besides, the cigar lighter socket is ignition switched, so inactive if the car's off. If your suggestion worked, he could already have got the trunk open by using the underhood terminals.

 

The mechanical trunk release provides a means of escape in the event of someone being locked in the luggage compartment. Adults are advised to familiarize themselves with the operation of the release handle.

The release handle glows in the dark and is located on the inside of the trunk. To open the trunk from the inside, pull the handle while pushing the trunk upward.

Return the handle to its storage position after use.

 

I think most adults would be hard-pressed to fit in the trunk, never mind being shut in! The OP is trying to open it from the outside with no power, and as far as I know, there's no access to the mechanical release except from inside.

 

The wiring diagram section in the original post is not the right one. Look two pages later. At the bottom left I see "BOOT REL MOTOR" and a black wire to C3BP01FR-6.

Of course, I have no idea where the CJB is. I've never need to find it before.

EDIT: Even though it says "BOOT REL MOTOR" it goes to "Latch - Tailgate."

 

That may be,, but perhaps with a little ingenuity, like one of those grab handle sticks, or some stout wire or cable with a loop, a walking cane, or even a bribed child. There is supposedly a spot under the license plate (???) for a manual key similar to what the side doors have?? The 'key' is a part of the fob. This shows it for the driver's door.

Any number of ideas that worked for Old British cars with cable releases for bonnet/hood trunk/boot that had broken. Only a real problem doesn't have a solution.

 

I'm not aware of any access to the hatch area via the "emergency key" as there is with the doors. There may be access from below to something. I'll try to stick my head under the back of my car later. It might be possible to get the luggage area cover loose and pull it into the passenger area enough to see the release. Once visible, it'd just be a matter of getting something hooked on it enough to pull it. There's no access for a child, whether bribed or even threatened, with that cover in place.

My previous post points to what I think is the correct point to activate the solenoid, but I haven't tested it.

 

That'd work for the X150 XK/R. The previous model (x100) ha dthe keyhole cleverly "hidden" in the XK badge. I guess Jaguar figured nobody used that so skipped it on the F-Type. Of course, you couldn't get out of the XK boot if you were trapped in it!

 

OK, gently please guys…..
I’m failing to understand why the jump terminals under the hood won’t bring the car back to life.
The positive must surely go back to the busbar and why should it matter if there is no connection to the battery?
So assuming I’ve got this wrong can someone explain where the positive under the hood goes to?

 

I just looked at the emergency trunk lid release in my MY2017. It is a "white" and perhaps "glow in the dark T-shaped handle that is upright at the rearmost of the trunk area... as if on the other side of where the lic. plate is, but on the interior. Got two photos, one with the trunk open for reference and the second from inside with the trunk lid closed. I was able to pop up the privacy panel off its hinge pins (behind the seats) to allow for that photo. Some manipulation would be needed to get the support loops off their pins, but then maybe that whole panel could come out.

 

I'm not sure either, but in first post states "I cannot use the front jump points." I don't know whether that's assumed, or based on empirical evidence.
