Assume I know zip about cars and help me understand please. I am presuming it is the software used to run our cars and why it would need refreshing is foreign to me. I mean, if the software worked before, what changed that would require it to be reworked/refreshed?

Also, is that something we (assume that I will try anything once) are able to do this were we to get access to said software? I have a friend that codes older BMWs. I wonder if he would know how to do this and could help/teach me.

I am rambling somewhat but am frustrated with my 2012 XK. Since I mentioned that....the infotainment comes on/off quite a bit at startup. The bluetooth for phone does not work. My speakers pop and crackle sometimes. I just installed a new AGM battery. I checked for codes using AP200 and erased the stored ones to get a fresh read. I may have bricked my car (I did) but worked through it when I cleared the stored energy via crossing the battery cables.

I do have an appointment at the dealer but really my only issue is the non-phone issue and the cycling infotainment.

Thanks in advance.

 

When your home computer crashes you reinstall the operating system, same with a car! If your lucky it's just the software,
unlucky if it's the hardware.

 

Thank the heavens this isn't 1995 and this being an IBM after going online to questionable sites...I'd be bricked! Ha ha.

I get why a computer crashes...you are adding software or is the result of some other external influence. But a car is a closed operating system. So, it must be either the hardware or a faulty long-term state of the operating system, if my logic holds.

If it is the hardware, there really ought to be a way where we (you and I) can bench-test our modules or other hardware units. I'd love to ****** out my infotainment unit and the modules in the trunk to test. (I know, I know...Jaguar has no obligation to make this easy for us...after they are, they are a for-profit business.)

 

Hi Speedmaster,

Failure of the touchscreen is becoming a real problem for X150 owners - see 'Failure of touch screen' in list for this forum and you'll see what I mean. I'm hoping that some enterprising computer literate person will eventually produce a compatible unit (updated) to replace mine - it's old technology now and it'll get to the point where there are no replacements available (apparently Jaguar are already NLA for certain ones !). I have the SDD program which shows up a code UO155 (loss of communication with instrument pack) but it can't tell me exactly where the problem lies (could be wiring, could be the screen unit itself or something inbetween ??) . I'm loathe to throw x amount of money at a second-hand screen unit only to find that wasn't the cause. Good luck with yours.

 

well to continue along that analogy, software is often developed with defective code. As time passes the error shows itself in the form of a defect. Hence a break fix is created and added to the software. I've managed software development teams in the past and sometimes issues take years to show themselves.
It's also possible that the code itself is stressing the hardware (though doubtful), but it does happen. I'm simply confirming your thoughts here.
Lastly, the hardware itself is the issue as you say. We or at least I, don't have access to the circuitry diagrams but there are still electronics repair shops that can work their way around lack of diagrams. So I would hunt for one, locally or not and have them take a look see.

Does anyone know if the code in the 2010 touchscreens is the same code used in the 2010 - 2015?

 

It isn't. It can be used to DIAGNOSE things.

Generally you don't need to change the software inside the car, though there are occasional tweaks/fixes (typically in the first few months after the cars were made as more people drive them and find niggles).

SDD is aimed at techs at the dealer and is quite user UNfriendly.

 

<smiling/> As enterprise software has been my business for 30 years.

I don’t really know where to start. You are correct, should the features at build day satisfy you, there is no need for an update.
Of course, since build day, learned through customer and technician comments, features were updated to address issues learned.

And incidentally, the failed bluetooth module could be initiating your screen issues. Simply taking it out of the loop would quickly confirm this.
Of course, a proper Jaguar/Land Rover code reader (like SDD!) would be helpful.

 

Guy - Thanks for the comments. I appreciate them and of course, makes total sense that updates would need to occur, especially since you learn things via feedback. My learning curve (and I think it has been answered by you and others now) was more about thinking that the code was somehow degrading/degraded over time. That made no sense to me and now it is confirmed...it doesn't. It is the same code but for any updates service techs have done. I am a finance guy so I am trying to learn what I can about how cars work, etc.

Now, onto the bluetooth...another member and I took some time yesterday and tested a bunch of things. Here is what (we think) we found:
- The MOST red laser is sending a signal; on for two seconds and off for one. That cycle is ongoing. I see that going into the bluetooth module and emerging from same. (Tested at the module but also in the source at the side of the modules.) I was able to do this by removing the outbound MOST fiber optic line, inserted the male connector and noted that the laser emerged from the unit. So, I think that the module is allowing the signal to come through and is not the source of the interruption. I need to test to ensure the module is getting power now. I pulled the 5-amp fuse and the infotainment shut down (the fuse looked good and this action confirmed power was getting to the auxiliary fuse box). So...need to test for power once I snag a new voltage meter later today. Too bad there isn't a separate fuse for the bluetooth module...would make that easy.
- Opened the kick panel fuse cover. Found a spliced-in wire with an inline fuse a la 1970s Pioneer stereos of my youth (you'd put a fuse in to reduce or remove the noise from the alternator.) We looked at this fuse box so as to look at the grounding point. Said grounding point could be the source of a few other error codes being thrown. I think the power line has something to do with an RJ connector sticking out of the leading edge of the headliner. My guess is someone prior to my ownership had a camera or a radar detector (something needing a power source.) Am hopeful that when I remove this wire and ground, we can be done with those error codes.
- We looked at the bluetooth antenna. It doubles for the sat nav antenna as far as I can tell. It looks like a solid piece of metal plate and I cannot figure out how to test it (ohmmeter may tell me continuity but what does that even mean?) I just ordered a replacement (used) for $25. I will try that. Besides, no phones can pick up the old Jaguar bluetooth source so the module or antenna are suspects.
- If the above all work out...I will be doing a happy dance and thanking all for your help. And then, I will start adding really cool upgrades like curb feelers (kidding). I love this car and I want it perfect, so I will be buying clips and such to secure all the panels that seem to be missing them.

One last comment. I bought an Altel AP 200. When I clear the codes and remove the USB...the car bricks itself. It literally will not energize the start button. In order to get the car going, I have to remove the negative cable and reattach. Then it starts right up. Go figure.

Thank you and all for all the support.

 

Speedmaster, Greetings. I’m not certain but I don’t believe the bluetooth antennae is integrated into satellite radio antennae. I believe it is integrated into the module itself.
I do understand your comments concerning “degrading software”. I too have seen comments to that effect. It is a little too close to 2001, a space odyssey, to me.
Thank you for the reminder. I had found a few grounding points that were loosened. One in particular for the screen; in the passenger foot well, forward of the front edge of the door, slightly below the glove box. It had clearly been tampered with.
Do let us know how you progress!
cheers!

 

Is there a way just to cancel the entire screen and replace it with some radio unit?, although that will need a new mount to make it look good in the console.

the only problem is that the aircon controls are through the touch screen??

Wondered the same thing. The BT module has an antenna connection and shows the location to be @ TM066 which is in the Aux junction box. I think he found it already.



Satellite antenna is in the boot. Not sure if they are the same or interchangeable part numbers but they are separate antennas.

 

Yes, Sean W helped me find the antenna. It turns out the schematic from the 2010 Workshop manual had it in the right place after all...you just couldn't tell it was in the area of the junction box. Am awaiting a replacement now and will plug that in. Am also awaiting a replacement voltmeter...since mine died. Once I have that, I can rule out power issues to the bluetooth module and check continuity at the current versus replacement antenna.

 

Maybe Graham is the knowledge around this one, but if anyone knows, please advise.

My SDD V130 has various modules used to update (as well as diagnose) my 07 XK's ECU's.

Questions: do SDD releases later than mine include later updates for my model?

Did JLR continually update the released SW as SDD versions were distributed? So the V149, for instance, might have later releases of SW for my car?

At the moment, V130 seems to do what I want -- but would V149 (last cracked version in the wild, not requiring Topix, I believe). have new SW features and fixes, making it worthwhile to upgrade my SDD?

Thanks!

 

I'm going with V130 has everything you need for your 07. SDD was released in 2012 I think (replacing IDS) which is also included in your version. I use V123 for my 07. I've looked at all TSB's that came out that had an impact on my model year and nothing dated after the version I use. But yes, maybe GGG has the release dates for each version.

Thanks, Sean. Really appreciate it. Read that last fall just after I got the XK. Amazing how reading it again made a lot more sense this time!!!!

My takeaway is that for an '07 car, and '12 software release, what I have is what I'll have.

 

So...how can you confirm which version software you are running?

 

You download specific versions. Here are release dates of each up to v146. I believe the last version you can download that can be used offline and includes SPA and VDF files is version 1.50.

This will give you some insights on how SDD operates.
