Hello
Since there are 5 fuse boxes in the 1998 through 2003 XJ models, I though it would be a good idea to identify what sources are available that provide the best information about them.

There are 4 sources that are on this forum Driver Handbook, Vehicle Care Handbook, JTIS21 Shop Repair Manual, and the Electrical Guides PDF files.

Divers Handbook
The only search results for the search term fuse resulted in going to the index that gave the Vehicle Car Handbook as the handbook to find the information.

2000 XJ8 Vehicle Care Handbook
Fuses and Fuse box information and locations also gives the fuse number (used to locate fuse in box ), fuse amps and the circuit info (Pages 4-12 through 4-20).

Example: looking for the LH air conditioning blower motor fuse, find it in the Rear LH Heal-board Fuse Box, Fuse number 11, Fuse 20 Amps and Circuit is Air Conditioning Left-Hand Blower Motor (page 4-19)

Relays and their locations Pages 4-22 through 4-24.

JTIS21 Shop Repair Manual
Fuses and Fuse Boxes information and location is found by using the Service menu – XJ Range then any of the Model Years (1998 through 2003) it does not matter which model year, the Fuse Box locations and information is the same.

Use the Text Navigator (brings up the index – list of 5 sections – General Information, Chassis, Power Train, Electrical, Body and Paint). Use the Electrical section, go down to 418-00 Module Communications Network, click on it and it opens to sub-menu items, click on Description and Operation, then click on Communications Network.

The Communications Network provides a vehicle diagram that shows all 5 of the fuse box locations & relays (Engine Management, Engine Compartment, Rear Left-Hand Heel-board, Rear Right-Hand Heel-board, Trunk Fuse Box).

It also gives for the details for each Fuse Box (diagram, fuse number, fuse amps, what circuit it covers).

The Electrical Guide PDF Files are also included in the JTIS21 Manual.
It has a vehicle diagram and fuse box locations, but I believe would take a lot more time to find the fuses and relay components information (such as what fuse box has the air conditioning LH blower motor fuse).

I could not find the fuse number references for the fuse boxes. A PDF search on fuse number gave no results.

Well, all that is quite interesting, but no where in your post does it mention that there was at least one significant change in fuse locations between MY 98 and MY 02. For instance, a popular blown fuse is the cigar lighter (dime on the console?) and that fuse location changed between two panels in those years.

 

Hi Ross (sparkenzip)
You are right. In April last year, I actually had to replace the Cigar Lighter fuse when my wife dropped a paper clip in there and shorted out the fuse.

I used the JTIS fuse information and it was not in the Rear Right-Hand Heel-board. I did find it later in the Trunk fuse box after I looked at the Vehicle Care Handbook in the glove box.

JTIS21 apparently has a mistake in it. The XJ models for year 2000 shows the Cigar Lighters fuse is in the Rear Right-Hand Heel-board – Fuse number 14 – 25 amps

The 2000 XJ Vehicle Care Handbook shows:
Cigar Lighters fuse is in the Luggage Compartment Fuse Box – Fuse number 5 – 25 amps

Even the 2003 XJ model selection maybe be wrong, it also shows the cigar lighter in the Rear Right-Hand Heel-board.

Thank you for the correction.

Jim lombardi

 

Yeah- I remember a VERY heated debate concerning that fuse with each side being absolutely right AND absolutely wrong.- Like the seven blind men with the elephant!

 

Hi Ross
You are definitely right about the fuse location in the trunk fusebox. I was not trying to say anything about the JTIS except maybe the manual is edited by humans and obvisouly the fuse location change was missed and never corrected in any of the future versions of the manual.

That is why I mentioned that it is probably wrong also in the JTIS for 2003 XJ series, maybe someone who has the 2003 XJ Vehicle Care Manual can confirm it.

Sorry if my earlier reply sugguested otherwise. I think you are one of the best contributors with a lot of knowledge that you share here on the forum. I wish I had some of hands-on knowledge and experience that your have. I was a teen-age wrench only.

Of my fuse box cover from my 1998 XJ8L...
(I wish all of them had this and they were correct!)

 

Hi Keith
Is this the fuse box cover for the fuse box in the boot (luggage compartment - trunk)? It looks like the one in our 2001 XJ8, but ours does not have any fuse charts on it.

Jim Lombardi

 

It is the cover for the fuse box in the boot. Only my 1998 XJ8L had it. My 1999 VDP SC does not have it....just plain like yours...

 

Can someone tell me which box the fuse for the trunk release is located? Please, not the trunk fuse box.....

 

The trunk release is controlled by the Security and Locking Control Module, which I believe is in the trunk... sorry. This problem has been covered in the past though, a quick search should help you out.


On a slightly related note, and because I always have trouble finding it, here is the wiring diagram for our cars
http://www.gusglikas.com/images/Auto.../jagxj1999.pdf

 

Speaking of fuses, can anyone help me figure out which fuse controls the panel lights on the overhead console, the center console and the instrument cluster and clock?

I was replacing a tiny, "grain of wheat" bulb in the ceiling console
when I managed to trip what I thought to be a fuse for the
instrument lights that illuminate the instrument cluster, the clock,
and center console and the driver side power window/seat pack.

However, I checked all the fuse boxes -- two in the engine compartment, two heelboards and the trunk box -- with a light probe and none are blown that I can tell. No 18 on the left side heelboard should take care of "interior lights" but it is good. Replaced it anyway and still no lights.

Other lights like map, dome and C pillar lights all work fine.

Ideas? Mine is a 2001.

 

The Trunk (boot) release button on the trunk lid (also the one inside the car) issue is probably the wires are broken near the hinge right hand side standing facing the back of the trunk(those wires run through that hinge).

Our 2001 XJ8 had several of wires broken inside that hinge a few weeks ago. Our indy mechanic was able to find them (I knew where to tell him to look from reading all about it on this forum).

Jim Lombardi

 

My trunk lights work fine.

But you think a wire in the trunk hinge may control the ski slope, gauge cluster and overhead console?


Huh

 

Len Apcar - no, I was answering an earlier post on the trunk release.

Here is a weblink to 2001 Jaguar XJ Electrical Wiring Guide:

https://www.dropbox.com/s/shod996k3s3xwmm/jzj2001en.pdf

Look at page 91, page 49 and page 41.

Page 91 - see Dimmer Module, follow the (O - outputs) to instrument cluster, clock, etc
also the (I - inputs) from ref 11 box - refers to fuse# 3 in left hand
heelboard fusebox - page 41. Also ref 13 refers to fig 2.1 on Page 49.

Page 49 - ref 13 has box that looks like a stop sign (WR wire color code) leads back to ignition switch then back to Body
Processor Module.

Here is a weblink to the 2000 XJ Vehicle Care Manual PDF file (the 1999 thru 2003 XJ Vehicle Care Manuals are all the same manual):

https://www.dropbox.com/s/c6y3yn81af...e_Handbook.pdf

Look at Page 45 - left hand fusebox heelboard fusebox. Fuse# 3 is the dimmer control. Fuse # 18 is the instrument cluster. Fuse# 5 is the Body Processor Module.

Hope this helps.

Jim Lombardi

 

Thanks, Jim, help as always. I will check out all the fuses you site and have a look at the guides.

And sorry about the confusion about the trunk wiring.

 

Len
Also you should review the Electrical Guide pages 63 (wiring diagram)and 64 (Components locations) about the Gear Selector illumination Module.

I noticed ref 13 circled that leads us to page 45 (fuse# 16 in LH HEELBOARDFUSE BOX). Not sure if this is that fuse is the problem.

Page 45 in the 2000 XJ Vehical Care Handbook - says fuse# 16 - Electrochromic interior mirror (where fitted), centre console switchpack, gear selector, traction control switch illumination, J-gate mode switch illumination.

Also says -Pin A9 luggage compartment fuse box, heated rear window relay, fuel pump relay, secondary fuel pump relay (supercharged). Pin A5: feed to fuses 10 & 12 in right-hand heelboard.

That why I am not sure that fuse is the problem.

Jim Lombardi

 

Many thanks, Jim, I will test all of these. In your experience, what causes a PIN to fail? I have never encountered that. Could it be a short caused by a tiny light bulb?

 

I don't think Jim meant the pin failed- Just that that is the pin in the connector that feeds the circuit in question. As to why a circuit blows a fuse, well, I suspect you know that is caused by a shorted circuit flowing too much current.

As strange as it may seem, I would suggest that after you check all the fuses, you try a "hard boot". And... how are you checking the fuses?

 

Thanks. I am checking the fuses with a probe/light tool with the engine running since so many circuits are not energized without the engine on. I touch one or both sides of each fuse.

Sound right?

Can these probe/light tools give a "false positive?"

 

Here is the fuse tester/puller I use:
