I drive a 2013 xfr RWD and the other day I noticed when locking I would get one audible beep then shortly after two beeps indicating a fault and that my car isn't locked. Checked pretty much every fuse because my manual is for a different car I think lol
Then I tried locking the doors with key fob and leaving them far from car and every door opened and alarm started blaring. Sat in the car and pushed both key fob and dashboard lock and unlock(lock button on dash does nothing) ,all I hear is gas cap and trunk functioning and absolutely nothing from any of the doors. Windshield wipers and washers work fine, Bought an icarsoft, updated it and did a battery reset in the BMS and still no fix. Disconnected the positive terminal thinking it was a glitch in the system and maybe slim chance but maybe it would switch it back...... nope. Does anybody have any ideas or suggestions
I'm kinda at my wits end with this and am trying my hardest to avoid taking it in to my local dealership
Thank you in advance

 

I had a similar issue when i disconnected the battery by mistake, which in turn stopped the doors locking and mirrors folding. I had it reset by a Jaguar specialist using an "Autologic" diagnostic unit & everything is working back to normal. Jag has a TB as stated elsewhere to replace the 2 modules. Very expensive to replace the modules.

 

good to know and something to keep in mind when I do tall to jaguar about this issue...... just one quick question...... jag has a TB???? Whats a TB

 

you wouldn't by chance know the type of autologic unit they used would you? Im guessing my $200 icarsoft isnt going to get the job done. What did u get reset by the specialist

 

Technical Bulletin.

I'm having similar problems but just the driver side won't lock - but the rest of the car doors work

 

thank you kindly sir. Someone posted this exact TB on a different thread the other day and i havent been able to find it again so this is good stuff. I wish i could do it myslef but i dont own that technical equipment and im sure it isnt cheap to buy. Again thank you

 

I could be wrong so please don't quote me and if a more senior member has a better idea, i would listen to him lol but it sure sounds like the motor has **** the bed on your drivers door, if all the other locks function except for that one door then my reading of many many threads would say the motor in that doors actuator is dead

 

Sorry I didn't ask about the unit but I can imagine most of the diagnostic models would work to reset the issue. My specialist said they are an expensive kit, but all owners of the units have good tech support set up with Autologic in the UK and any questions to them get answered within 24 hours

Here is a link regarding the issue I had being discussed by others in the UK & how they have dealt with it...Interestingly the factory SSD unit doesn't register the fault.

 

thanks I'll click on that link and have look to see how others have been dealing with it. Someone added jaguars TB and within it has both workshop and diagnostic procedures. When they say "renew" central or aux junction box they mean take out old and replace with new ya?? I wish it was as easy as downloading this sdd software on a laptop and pluging the laptop into my car so I can do it myself. I've got an ever growing list of possibilities people have been posting on here and other sources ive reached out to and they all feel very strongly it's the issue. It's getting to the point I'd like to rip all of jaguars crazy *** wiring right out like gut it electronically and get it all redone a much more simpler and basic way

 

Yes this is the puzzling part?
The Jaguar TB claims both junction boxes need to be replaced (Or renewed in Jaguar speak) and can't be fixed any other way. But we have a number of people using Autologic (Never any model number either so which Autologic device was used?) to reset things without replacing the junction boxes?

Some have used SDD to reset the immobilizer and that seems to work sometimes too?

yeah I've come across many threads on this topic and it seems more people have had there issue resolved from the autologic software as opposed to jaguars own sdd software, which i found to be rather amuzing.
Replacing both junctiojunction would say is nothing more than a money grab, I've come across 4 or 5 individuals that have fixed the problem simply with the autologics diagnostic tool and replacement central or auxiliary junction boxes. One of which I do believe is a part of this thread too lol.
can u download this autologic software or is it just strictly on those little blue boxes??

 

The rework gets your locking back, but doesn't fix the problem, if you disconnect the battery again you will loose the locking again. Changing the fusebox as the TB fixes the fault so you can disconnect the battery safely.

 

I fixed mine using sdd
There is a process to go through if you want to disconnect the battery and not scramble the security brains

 

if ever I have to disconnect the battery to change it out I will just hook up a secondary power source while I make the switch but yes I'm up ***** creek without a paddle if there ever comes a time where I am required to disconnect the battery

 

The other strange thing is it's only on 2013-2015 XF's? At least that's what the TSB states.
Jaguar uses so much of the same stuff across their car line it's hard to believe it's just these select few cars?

I have an XJ but still am reading this in case the problem does start showing up in other models.

Really wish we could get a explanation of what is actually failing in the junction boxes. Seems like a huge expense that could be avoided if the correct repair was known?

you wouldn't happen to know what jaguars prices are for central and auxiliary junction boxes? I want to see if i can buy them off ebay cheaper and bring them with me to jaguar when and if i end up caving and taking it in lol

 

I was quoted from JLR dealer A$4000 (US$2700 approx) to fit up both modules. For the amount of times I expect to disconnect the battery & maybe require a reset , A$90 is a steal from the Jag specialist

 

WOW!!! That's seriously a ridiculous amount of money. I could buy an autologic diagnostic unit for way way way less than that and buy a back up battery or some other form of power source to hook up to if ever i need to disconnect the battery lol
that's crazy
