Problem with the general interior lighting cluster instrument. No instrument cluster ilumination
Jaguar sType 2001, 3L, v6, SE Exe, (CCX) , 175KW, Gasoline

Symptom:
All functions and warning lights in cluster dashboard OK
Potentiometer light board intensity and functionalities (variable roller / resistor) OK
Position lights and all interior lights OK
Checked electrical fuses in the passenger compartment OK
Radio and Air functions lights OK
Door function lights + gearbox light FAILL !
Interior light instrument cluster , general illumination bulbs FAILL !
No error code on dash.
No error code on diagnostic.
No other electronic dash advise

Story:
In the morning when I turned on the positions, the cluster instrument light, turned on with a delay of about 2 Sec. The next day it no longer worked as an interior light only as functions and warning lights.

Please can someone tell me what happening?

Thank you !

 

Hi DanIzvernariu

So when you say gearbox light fail, are you referring to the transmission mode switch on the center console ( Snail )?

Since most of your issues seem to be related with interior lighting, it may be related with the General Electric Control Module. This will be located in the Front LH side footwell.

Just out of curiosity, have you tried checking the battery first, is it charged? If so, try a hard reset and see if that changes any of your symptoms, let us know what you find

Hi J!
Of course, the battery works properly, it's new. I tried to reset the system but to no avail.
Basically I'm talking about the general green light in my case which in the gearbox changes to red once you move the shifter position or the same as the door function indicators (mirrors, windows lift, etc.)

 

Take a look here, see figure 09.2 for dimmer-controlled lighting:

http://www.jagrepair.com/images/Auto...x2022001en.pdf

If I'm reading the diagram properly, those lights are all getting power via the General Electronic Control Module, shown towards the upper left. Note "Switch Illumination Supply" in the center of that box. If you follow that upstream (53S inside a circle), this will lead you to fuse F33 in the Primary Junction Box. This is a small fuse panel inside the cabin, in the door pillar area near the hinges for the forward right door. While you're in there, check F20 also.

Edit: Forgot to mention, look at the many lights on that page of the wiring diagram. Figure out which lights are not working. If all are inop, that would point towards the fuse.

If only some of those lights are not working, look to see what else is inop. There are MANY lights on a big circuit with MANY branches. If you can identify a particular branch that isn't working, you could have a partially shorted bulb in there. It might draw enough current to pull down the voltage on that branch, but not enough to blow the fuse.

 

You will need to check the fuses again to make sure they are ok - as stated above. Pull them out and check them.

Past that, you may be following a wiring issue ( chaffed wiring, corroded plug at GEM or anywhere else in line ), or the GEM itself is starting to fail.

 

Thank you so much! I appreciate! I will check first the bulbs on the instrument cluster this Friday ( i think?!) and ,yes I check fusible 30 in a passenger place box. Is Ok ,and all fusible arround too.
Well I will keep U informed for curiosity .

One more thought:

Park in a very dark spot one evening, away from any streetlights, Antifa riots, etc. Turn the dimmer full bright and you may see a group of lights illuminated dimly, with one still not working. Look at the wiring diagram again and you may find they are all on the same branch of the lighting circuit. Replace the one light that was totally dead and this may bring the others back to life. But unless you look under very dark conditions, you'll never see the dim lights and will think they were all totally dead.

 

******
))))) Oky I will do! )))
Wirinh diagram if I m not wrong, look like serial circuit for bulbs. So, you habe right, maybe one or more bulbs are off.
Thank U!!!!

 

No, the bulbs are all in parallel. It's not like the old-fashioned Christmas tree lights (wired in series), where one bad bulb would take out the entire string.

Any progress? Curious if you found some bulbs shining dimly, versus being totally dead.

 

Hello Karl!
Thank U for trend support.

Today was the day!

I disassembled the instrument cluster and found this, see image ibelow!
So i wasn´t lucky! The bulbs are OK but I found this faill and i think must to change the instrument cluster
The problem where I can found another one ? See other problems after ...codecs etc.

 

Ooh, good find. As far as replacing the instrument cluster, I'm pretty sure it is a big deal. IIRC, this component is the heart of the security system. Hopefully somebody with more knowledge will chime in, but I'm pretty sure you can't just swap in another unit (new or used) without some programming specific to the VIN. You will probably have to find a Jaguar specialist in your area to have this done.

 

Yes in did !U have right! Hopeful I will try to consulte an electronist service near me. Iknown that is hard to change this entire itms. without code . So, will shell see next week.
Thank U!

 

At least you found the problem.

As for replacement - you will need a Jaguar dealer or someone who access to the programming software ( WDS, IDS, SDD ) to program. I have seen where things like this can be repaired, someone who repairs computer circuit boards, etc., worth a try.

Otherwise if you do have to replace it, you'll definitely need the software to program to the vehicle. Preferably someone who has access to the genuine diagnostic. You will also need 2 keys and both remotes. If you don't have 2 keys, there is a way around using only 1, involves using some foil, same used for cooking.

 

I'd think a repair would be best if possible.

 

Right Norri! Yesterday i visit electronic service here in Madrid. They talk about 300 euros or around.

 

Top notch suggestion. If the board can be repaired, I think that would be a much easier route.

While you're at it, look at this thread. The early models have a known issue with a flickering odometer display. Details here on how to fix that:

It might be worthwhile to check for this problem (physically inspect the suspect capacitors) and get this done at the same time.

SOLVED!
For your information about symptoms ,please read my actual post!

The fact that I

no longer had service lights on the cluster instrument was due to a short circuit at the electronic level, see the image below.
The repair cost about 150 euros, 2 year warranty.

 

Good news!
