O.k., I've been reading for 3 years now and often hear this term.

I even saw it on a response to my recent post, and I just thought eventually someone will describe it so I don't have to ask.

Is it just dead car, or something specific with a known cause or fix.

 

Bricked - Engine Management Computer or other critical computer module, often rectangular in shape, like a brick, has failed.

 

Thank you.

 

Does anyone think I am now "bricked"

I posted recently about (My confession) boosting with poles reversed.

I think I got lucky, based on the advice here, I replaced battery, and fired up with only a bad fse for climate fans.
----------------------------------------------------

SATURDAY: Fast forward to this weekend, SATURDAY I started it up and ran it for a few minutes arund my neighborhood. I just didn't want brakes or anythng to rust up or anything from sitting for a bit. (LEft windows down because weather is nice and warm and dry, seemed a good day for that as I lead up to storaing for the winter.

SUNDAY: Went out to lock it all up and close the windows. No lcd screen and no response from Stop/Start.
I clicked for anything, 4-way or emergency flashers were on and fine.
Trunk light is fine.
Everything else seems dead.
------------------------------------------
Am I possibly "Bricked?"

Any advice? Appreciate anyone taking the time to respond.

 

Then what's wrong with your car?
If it's working your OK.

Hi Clubairth1, sorry I told the long story. (Short story below, below the dotted line)
It WAS working fine after battery replacement, even 2 days ago (Saturday) started it fine.
Somehow, the next day after (Sunday/yesterday) I have these symptoms.

Start at the beginning. What is the cars voltage after sitting all night?
If that's within range see if you can read any codes.

Take the car to Jaguar or Range rover dealer so they can reset the battery modules, done in 15mins, don't try anything else unless you have a good scan tool like SDD or icarsoft v3

 

charge your battery. it’ll probably come back with a smart key not found warning. 13 and up all have bad front bcm/sjb

 

Thanks for all the feedback.

On another lucky note, I just gave it a final try before calling the towing company.

I pressed the Park Brake, and brake pedal and start and it fired up.

All this adds up to me needing to learn more... others in the forum likely would have just done this and not even posted. It's all a bit new for me.

@Dennis - I think I will pickup the reader, if you (or anyone on the post) has one that works well, or recommends, I'll go get it for future events like this.



Thanks everyone,
Rob in Eastern Canada

 

Congratulations Rob! That was a win for sure.
Plus as you said we have so many dead end threads where they never come back to let us know if it worked or not.
I call them hit and run posters!

Hi Dennis, can you let me know any model or specific markings on the icardsoft you refer to, or that you use yourself?

I see several on eBay and other vendors, and some descriptions say Mercedes (icarsoft MB v3, where MB=Mercedes).

I searched, the advanced search on here also and all searches bring me to X260 but I'm a X250 so I fear I'll buy the worng one.

Noticed on your videos, looks like you have one in my year range.

 

Go on Amazon, and look for icarsoft V3 Jaguar/Land Rover

 

O.k. so the story evolved since my last post.

Maybe this is a new problem.
Maybe this is related to my ongoing saga above.

----------------------
September 30th, above you see that everything powered up fine.
Drove it off and on (I'm not a daily driver) for 2 weeks, parked.
Maybe 3 or 4 days only sitting idle, dead.
Put a maintainer on it and dead car.
(Putting charger on battery registers as charging, or I mean the maintainer light pattern changes color so I know its taking charge.)

Unlike September, threre are no lights, no response, nothing.

-----------------------
I guess my quesiton is, Is there a main fuse, although there's no event to suggest a fuse would or should blow, the behavior is 0 no power anywhere.

I told the lengthy back story in case anyone can pick apart the history and symptoms and suggest anything.

I'll leave this post sit a few days then send it to the dealer as Deniis suggested last month.


Rob

 

Your car has a current drain and you need to find it. If the fuses are not blown what are you going to do with the "main" fuse?
You still have not posted any numbers concerning the voltage of your car?
What is the voltage after the car has sat all night?

Everything you have posted points to a current drain. No resetting the BMS will do nothing.

Good point - and in case it's not clear that's "What is the voltage after the car has sat all night (with maintainer NOT connected)?"

 

Thanks Clubairth and JagV8,

I didn't take the battery reading, I took the battery to the store of purchase and got a warranty replacement.
(I doubt it ever was a bad battery.)

I know that this doesn't solve anything.

I'll get some good numbers after I install that one. I can start the troubleshooting after that.

Will update

 

Unfortunately, Jaguar has a bad reputation for electrical/battery issues, so much so that there are numerous youtube videos telling you not to consider buying one at all ( which I think is a bit drastic)
I would suggest , as a minimum , prchasing a cheap multimeter that can read voltage- a few dollars from anywhere, or even better a battery tester like Autel (and others) also sell, if you need plug & play and want to pay the money
Also , as suggested , an OBD2 reader ....even a very cheap dongle that plugs into the OBD2 port and talks to your phone will allow you to read , and often clear, error codes- important if you ever go into limp mode for no fathomable reason !! ( I have one permanenty plugged into my XF)
Hopefully you get this all sorted , but battery issues are the bane of this marque IMHO

 

I run a combo USB port and DC voltage gauge that plugs into the cigarette lighter in the console. Cheap and the cars real voltage is displayed all the time. The cost is very low at around $20 or so and there are thousands of them for sale.

Sorry for the continued battery questions but over the years the battery has caused tremendous grief and that's the first thing to check and eliminate when you car starts acting up. It is shocking how many cars have magically been fixed when the battery has been squared away.

I can't explain it either as my 2014 XJR OEM battery lasted 10.5 years! I only changed it because I had never had a battery last anywhere near that length of time.

Hi, I'll have to report back next weekend.

I only want to leave it idle one night for feedback, then I need this on it battery maintainer

. (Item model, is suggested from other posts on this forum - Thanks again )
