hello, i work for a jaguar indy, the owner is a little behind on the times and im looking to update things a bit. we have a few cars at the shop right now that have immo problems. also a few cars with wiring issues. i need solutions for both resetting immobilizers and wiring diagrams and repair manuals. also if theres any solution for coding and programming modules for vehicles new and old. thanks

 

****, from the sounds of things, your shop needs to get a subscription service through Jag for access to all their diagrams. This will also give you access to update modules when using their diagnostic software. Not going to be necessarily cheap, but if you need access to the stuff that you saying you need, this is about the only way you are going to get something that will fit. You will need to do some looking into getting a "Topix" account. If you do not do a lot of Jags, then you can get access on a more day by day routine too. That may save some money. A days access fee is like $50, but this gives you access to all their diagrams at a minimum.

If you give us an idea of what vehicles you are dealing with, we may be able to help you out and give you some pointers on what to check and the common faults for those vehicles.

 

we do cars from very old all the way up to very new. i would mostly be interested in used module adaption and immo work than wiring diagram if i had to choose. have you used sdd?


i have an xtype at the shop right now, no crank no start, has some immo codes. customer says it will start randomly here and there.

got a 2000 xj8 with immo codes as well that wont crank.


got a 2006 xj8 that has water all over the place and has a bad parasitic draw. suspecting a few shorted modules as the culprit. was looking into that one today should have more results tomorrow.

and theres an xfr that i havent looked at yet but am suspecting immo related, crank no start. i think 2009 year not 100% sure.

and i am sure i will see many more cases like this in the future.

anyone have any luck using abrites?

 

2006 xj8 basket case haha

 

cheap and cheerful is get a chinese mongoose and learn how to use IDS and SDD. bare minimum if you're running an indy, or an old autologic blue box. shops are basically giving those things away

 

how is the auto logic for coding and programming ?

what is mongoose?

 

you guys need to do a lot of catching up. pm me

 

****, atleast for the X-Type, based on what you are describing, I would be looking at the negative battery cable first. That is known to cause what you are seeing. The next question on that car would be whether there is a red light on the center console when you go to crank the car (light is next to the coin holder which is the black plastic piece there by the e-brake). If that is lit, then you have to determine if the problem is a bad keyfob (a second keyfob will answer that) or whether your instrument cluster has bitten the dust (issues with that not indicating properly?).

The other cars, I would need to look at some diagrams that I have and see what I can figure out.

On that note, you may want to look around and find a copy of what is called "JTIS". This file we have on this site is going to have the wiring diagrams for the 99-06 vehicles. That would atleast be a start. It also gives some helpful troubleshooting guides and whatnot for various issues.

 

the xtype has the red dot lit up.
does sdd or jtis give operation description of systems or components ?

 

A bit odd already to have multiple Jaguar cars but know so little!!

 

Welcome to the forum ****, maybe you would like to stop by the New members Section post an intro and tell us something about yourself?

 

****,

Welcome to the Jaguar Forums. It's great to have you with us. I look forward to reading your introduction.

Many reference documents can be found for free at jagrepair.com, hosted by our member Gus and offering hundreds of Jaguar factory documents like Technical Introductions, Electrical Guides, DTC Summaries, Workshop Manuals, TSBs, etc. Many of these files were provided by our member motorcarman, a former Jaguar dealership mechanic, long-time independent Jaguar specialist, and one of our forum's most knowledgeable gurus.

Many Workshop Manuals and other documents are also available here at Jaguar Forums in the download areas of the model forums (e.g. X308, X350, etc.). Follow links in the "sticky" threads at the top of each model forum for "How To Quick Links" Many of these threads have links to downloadable technical files, including many Workshop Manuals.

You might also call local locksmiths to see if any may be knowledgeable about Jaguar immo systems and may be willing to consult with you to jump-start your education.

Cheers,

Don

 

**** xalty does not post very many words but he is a top notch commercial Jaguar mechanic and I would take him up on PMing him additional questions.
I think you need to invest in SDD at the minimum as he says. This is too important NOT to have for a independent Jaguar repair shop.

In fact I wonder how you got along so long without it? I am merely a Jaguar car owner and SDD has saved me (and my friends!) probably thousands of dollars at this point. Now it will be a frustrating experience (Learning curve??) because SDD is so hard to use but it will be worth it!

Hopefully you will stick around as you have plenty of real world experience and we could all use more of that!

im most experienced with bmws honestly, i have ista (bmw version of sdd) and all the special tools yadda yadda. i just started working at this place a month or 2 ago and ive began to lose my friggin mind with out all the information im used for the bmws. ive pmd xalty, hopefully he can give some guidance.

 

Yes with all those Jags plus a Rangee or two I can see your need!

yea……

 

its been an interesting ride so far to say the least haha.

the f pace was probably the most interesting trouble ive run into so far. had a dead miss of cyl 3. was totally gunked up haha, i posted a short of the f pace and some other train wrecks

 

Those are a mess!
Hurts to see so much destruction!
A quite nice collection of Jags too.

Was that the tail end of a blue Mustang on the lift in that first picture?

****, the JTIS is going to give some system description and how the system handles various signals. SDD doesn't quite do that. It more or less assumes you know about the car and that you know how the various system work. Very powerful tool, but it takes a bit of knowledge to really be able to use it properly.

As for the X-Type, I would see about getting a second key for it. The red light is saying that the number in the key fob is not making it to the ECU. Its path is from the key fob, through an antenna ring around the tumbler, runs through the instrument cluster, on to the CAN bus to the ECU. The ECU gets 2 signals, the key number and the command to start the engine from the tumbler. There has been a common problem with the instrument cluster getting broken solder joints on the main plug. Kinda like the CAN bus runs from the instrument cluster, through the radio, through the climate control, to the ECU. This is where the SDD software would be helpful in that it would come back and most likely tell you that it is seeing a problem with the wiring between Module A and Module B. Worst case, you tell SDD to run a test on the CAN system and it will tell you which modules it can communicate with and that will give you a good point to start wtih. SDD software can be gotten through places like E-bay. The big thing that I will tell you is that the cheaper it is, the more problems you are likely to have to get it up and running. So, if you have time to work and get a computer set up, the $100 kits work wonders. But, if you do not want to spend 10+ hours trying to get the software installed and tweaking this and that, you may want to spend the $1000 on a ready to go set up. SDD will cover most of your 1996-2018 vehicles. Starting mid 2018, the vehicles switched over to a system called Passport (as I recall). Same idea, just a different program. Not sure how well the SDD may work on say a 2020 vehicle. A lot of stuff is the same, but is it enough the same to work?

 

anyone got dlc pin out? 2006 xj8. trying to see what network is staying awake
