Central Locking Problem with 2013 XF Portfolio S

[Jimbob64]

Another update...

I couldn't easily get the vehicle to a suitable garage due to my location and distance required to drive so I got myself a Mongoose OBD cable and SDD software and after much hair pulling I managed to get some success...

It appears that my fault is down to the dual battery fuse box (part number - CX23-14K131-BC)

It's easy enought to get to and replace, I just have to find one now...

If anyone has one hanging around in their shed/kitchen draw/man cave then please give me a shout..

on another note, I managed to restore the central locking using the SDD setup 🥂

I think some of you might also be on one of the other threads about this subject but I put a bit more info on the other post so here it is on this one...

As something of another follow-up to this post it seems there is something of an increase in the number of Indepenent JLR service centres that have Autologic that are working out the fix. I've got to have the timing belt on my XF changed imminently and I'm looking to see where the best place to do it will be. If I take it to my local Jaguar main dealer I know they'll try and rinse me for the official fix when the security module inevitably fails as a consequence of disconnecting the battery!

As such I was doing some more digging to find alternative solutions to this and came across a thread on another owners club forum which showed a way of buying a cable with an 'unofficial copy' of the JLR SSD software which would allow you to reset the immobiliser module which appears to temporarily resolve the issue (the only long-term fix is the replacement of two junction boxes at great expense!).

If you look for the post from Viyasan7 from November 2019 he describes the fix and the kit that's needed. This might be a better solution for those of you that aren't near an Autologic-capable Indy. There were some caveats about clone cables and I haven't done this myself so it's very much up to you as to whether you go ahead with it.

There was mention of a TSB and indeed there is, but the only one I could find was for the North American market so perhaps that's the reason why the UK/EU/RoW dealers look blankly when we describe the problem. The TSB number is JTB00545NAS1 and here's a link to what it shows:

It's interesting how the TSB suggests reprogramming the immobiliser module as part of the fix, but only after the two junction boxes have been replaced. It would seem that this step, if done on its own, would be a temporary fix but perhaps JLR aren't prepared to only offer this step. I think it's a !Removed!-take that this issue, which is clearly a systemic failure of a part that should last longer than it has, is being ignored and the high costs being passed to us. 

Good luck all!

 

Incidentally the fix that Jimbob described is the same as the one in the other forum that I've quoted so it seems that it's becoming more widely known about.

A great post.  Thanks for sharing Simon.

Jimbo64  could you tell us where you sourced your Mongoose OBD Cable & SDD software perhaps with relevant links?

Have you fixed your problem yet?

Best regards

Hi all. I was going to update when the vehicle was up and running. It's still not.

To save a lengthy post see: https://www.jaginfo.org/threads/help-with-sdd-smartkey-problem-and-others.113707/#post-2885067

I'm currently in the process of replacing the GWM and DBM to try and cure the battery not charging issue. The key problem was easy to sort (but will reoccur if CJB is not replaced/flashed). If and when I sort the charging problem I will remove the CJB and have it flashed.

I've also been very busy so haven't had the time to work on the Jag - I'll update when things change.

This is the cable and software - https://www.obdiitool.co.uk/wholesale/jlr-mangoose-sdd-pro.html

The software (V160) and cable were£32.00 and take about a week to arrive.

I use mine on Windows 10 pro (took a while to install correctly)

Good luck

Wow, I thought I had updated this thread...

The Jag was fixed eventually. Turned out the new alternator was faulty (or at least had compatability issues with the ecu) so took a punt and fitted another. After a reset all was fixed. I had loads of help and advice from many people so thanks to all.

On a sadder note, it was written off earlier this year and is no more 🥲

I'm selling all of the modules I bought on eBay atm so if anyone is interested give me a shout.

Adios.
