2011 XK rear license plate lights not working. I checked the bulbs and they are still good. Any Idea as to which fuse is for this circuit?

 

seems there is a factory recall on this issue. Found the info on this site

No: JTB00226
Issue: 1
Date: 11 JUNE 2011

SECTION: 417

Rear License Plate Lamp Illumination Inoperative

AFFECTED VEHICLE RANGE:

XK (X150)
VIN: B32964 - B44070
Model Year: 2010 - 2011

CONDITION SUMMARY:

Situation:
The rear license plate illumination may be intermittent on vehicle start-up when the headlamp switch is set to auto lamps. This may be caused by the Auxiliary Junction Box (AJB) software misdiagnosing the rear license plate output as being a short-circuit to ground.

Action:
In the event of a customer concern of the above, refer to the Repair Procedure outlined below to update the AJB software.

PARTS:

No part [...]

 

Interesting! Glad you were able to figure it out--this is the first I've heard of it.

 

I am having this issue now..at the dealer now...they and Jaguar USA claim there isn't a recall. .but my Vin number falls within the range. They said there isn't a recall number to reference. Please help asap

 

It appears to be a TSB, not a recall. A TSB is just service advisory. The TSB number is JTB00226.

If your car is still in warranty it will be fixed for no charge. If your car is out of warranty, you likely will have to pay.

 

Correct.. it is a TSB. Seems is should be recall since the light is required by most states.

 

Is the JTB00226 something that can be resolved at home or do you need a special tool/link at the Jaguar dealer?

 

I have the same issue on my 2010 XKR. Good to have that TSB information.
Thanks

 

I had it. Dealer did some sort of "reflash" that fixed it. It's not a bulb issue, it's a control module issue. If the reflash hadn't worked they would have had to replace the module. More pricey.

 

did you ever post the part number for the hose that cause the leak on the rear of your XK 2010 engine. I had the same thing happen to me today in my 2010 XKR. On the interstate, shot up to 110mph, ac went warm, low coolant light came on, it was 106 degrees out here in scottsdale Arizona. Do you have the part number to the hose that was replaced? And what was the cost of the repair?

 

Posting on the wrong thread? You'd probably do better to PM for an answer to your question.

 

2010 XK. - License plate lights did not work. I did the trick of touching the two battery cables together for 20-seconds. - That Worked!!! - But... When I just took it to get it Inspected, it did not pass, because it had lost it's "Faults Codes" for emissions. They said I needed to drive it 150-miles and bring it back. - Question: Is there a way of getting those Codes back quicker? - Thanks.

 

I think you need to go through a long drive cycle. See this thread:

Thank you for the follow-up.

 

Fyi and hard reboot of the battery will only temporarily fix this issue. Next key on cycle will turn them off again. You need the software update for the rear junction box(rear body module)

 

Hi
I know this is an old post, but I have the problem of no License Plate lights on my 2003 XKR. I have tried the process of disconnecting battery leads and shorting them together a couple of times, but no joy. I have checked the cable and all in good repair. I have checked the fuse to the rear light that is supposed to be on the same circuit. Nothing corrects the problem. I have read JTB00226 - but this seems to apply to later models than mine. I see that the middle seat is supposed to be removed to get to the junction box - but my rear seat seems to be one piece.Maybe becuase I have an earlier model?? Also, the trunk button on the outside of the trunk has never operated while I've owned the car - but no big deal, the remote works and the button on the dash works. All seems to point to a faulty auxilliary board??? - Anyone have thoughts?

My options seem to be to try the dealer (closest to me is Mobile, AL), or to simply wire the bulbs to the tail light. Any problem doing that? it seems like a simple fix?
Thanks for any suggestions!
Neil

 

I'm afraid you have posted to the wrong forum. This forum is fo-2015 Xr X150's (2007 through 2015 XKs) You should post this in the correct forum, which is for X100s (1997-2006). You sould find what you need there.

 

Sorry Ralph - and thanks for the head's up. I am a newbie on this site. Will search the X100
