Hello,

I have a jaguar XF 2012 and there is a plug in the trunk near the battery and i cannot figure out what its for. Could you please advise ?

Also, my parking sensors and camera is not working ? Could it be possible its because of that plug ?

I have attached the picture. I would really appreciate if someone could help me!

 

There will be many unused connectors on the car depending on what options are missing. That one could be for the sub woofer if you don't have it under the spare wheel. The main fault that stops the camera working is a broken wire within the truck lid loom. That's the one near the hinge. It's fairly simple to remove and replace.

 

Should i lift up the spare wheel and check if that plugs somewhere under the wheel ? Also, i checked all the wires and none of them are broken. I replaced a wire long time ago when my trunk sensor wire was broken. Do you have any other suggestions what should i check for to fix my parking sensors and camera ?

 

That spare plug is odds on to be for the boot mounted sub-woofer which was not part of the base sound system. Take the spare wheel out (it looks like you have a space saver) and if you have a sub-woofer it will be underneath. But I'm betting you don't have a sub-woofer.
As for the parking sensors and reversing camera, I agree with glenno the most likely culprit is one or more wires have broken or at least badly frayed in the boot loom. Sometimes they can look OK from the outside but still be broken internally. Best bet is to get a new loom, look on eBay, not that expensive and as glenno says fairly easy to replace.

 

Judging by the picture of the connector, it doesn't seem to be used for anything because its still taped up. If it was being used, the white tape wouldn't be around the black part of the connector.


As for your park aid/camera fault, yes it is possible the wiring harness that runs up the trunk lid hinge could be broken due to opening and closing. However, if you have a fault within the park aid system, you will get a message on the touch screen saying camera/park aid fault please consult your dealer. When there is a fault in the system, it inhibits the use of the reverse camera. You can take a stethoscope, take the end out so you just have the hose, have someone sit inside and put it into reverse, place the hose up against each sensor and see if you hear high frequency clicking. If for one sensor you don't hear anything, that's your faulty sensor. If you hear the clicking in all 4, then you'll need to get the codes scanned to see what's causing the fault.
