Good afternoon all.

i currently have inherited the issue and hope of sorting this jaguar xkr issue.

its been in and out of various places inc dealer. And nobody has been able to get to the bottom of this issue as seen below the display screen is stuck on this odd screen and wont allow to exit.

is this something anyone has come across before?

i belive a few modules have been replaced in the hope to sort it but not the screen it’s self this is about all I know really.

the only faults i get that may be related are in FACP I get.
u0155-00 lost coms with instrument cluster
u3000-55 controls module.

battery has been replaced and verified as good.

any suggestions or help greatly appreciated.

thanks Ed

 

This does also have knock on effects to the HVAC and parking systems and all stereo functions.

 

Define “battery has been verified as good”.
Also, I wonder if the base image has been corrupted by “hacking” the sdd options. But you said it went into the dealer…. what fix did they attempt to do?
Was a system reset completed?

Thank you again for your response.

the battery after sat over night was 12.05v
with 720cca. And at idle 14.02v

i found out some more information last night
around 18months ago the vehicle had a drain that killed the battery upon battery replacement the car wouldn’t start.
This is when the mobile jag specialist came in and got it running again by replacing various bit but wouldn’t ever really tell anyone what he’d done. But the screen was left in this phase and interior in bits and he never returned to finish up and went awol.

it then went into jaguar who did software updates and trialed various black box modules to check and checked for wiring faults they couldn’t confirm it wasn’t a screen fault as were not able to obtain one.

What do you mean by sdd hacking ?

I would assume sombody has done a reset. If not is it something I can do with standard diag not jag ?

Many thanks

 

Looks like a diagnostics screen. I’ll tag @Sean W as I recall him mentioning Palmyra before, and maybe he’s been on this screen before.

 

The screen is updated via Palmyra. You are seeing a log screen attempting to boot and failing though I'm unfamiliar with the acronym EMG. Solution is one of two things. Replace the head unit or flash the head unit.

 

i agree, a reflash as something in the boot loader is unrecognized or failing. Thus I proposed a hack of the module is the culprit.
I classify the “reset” as a “hard reset” and a “soft reset”.
The “hard” consists of a reflash of modules. The “soft”, a flushing of volatile memory and a “reset” to factory module settings typically handled by a battery disconnect procedure.

Incidentally, 12.05v is significantly insufficient. And when the engine is running, you are reading the system voltage as generated by the “alternator”. You are not reading the battery voltage.

Lastly, no; “a standard diag” does not exist for many JLR options. Including screen programming, that I am aware of.

 

Yes the battery is bad. I don't understand what you mean by SDD hack and neither does the OP @guy Please elaborate

 

My apologies, of course.

If it were touched by unknowing, meddling hands, I would not be surprised if the sdd configuration file included an unrecognized option. Possibly sourced by a typo??

I only suggest this as I saw in the provided picture that some form of disassembly was at play.

It is very uncommon for the device to not boot. Unless of course there is a failing component or a misconfiguration of the module or the hardware.

 

As per the workshop manual, correct the poor state of electrical charge, first.
Then clear codes,
Then reread codes.

If you're still throwing U30055:Stored vehicle configuration data does not match • Incorrect car configuration data received

Re-configure the RJB using the manufacturer approved diagnostic system. Clear DTC and re-test. If the DTC remains suspect the telephone module, refer to the new module installation note at the top of the DTC Index.

 

Thank you all.

I will drop a new battery in it tomorrow as it’s under warranty only a few months old.

if it were to be the screen at fault do you know if a second have unit would be plug and play or do they require coding ?

thanks again

 

Forgetting myself I do have Landrover sdd software and I believe that covers jaguar. I shall have a look through on their tomorrow and let you know how it goes.

thanks yet again
