Jaguar Repair Problems? Ask a Jaguar Repairs Expert.
My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
Inspect for any shorted or damaged wiring or electrical connections to the tail lamp assembly.This will usually cause premature and repeat failure of the lamp assembly like this here.If any wiring or connection issues are found the affected fault located will need repaired to correct this issue.If this is or was checked and found o.k. let me know so we can continue.
If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.Thanks Pete.
When it failed (the cluster assembly) did you see any burnt or damaged electrical contacts in it?
O.k.,looking at the info on this model here the rear electronic control module (RECM) powers and controls the left rear and right rear light cluster assemblies.If you have no damaged wiring or wiring connections leading from the light to the RECM I suspect the RECM is surging voltage signals intermittently to the left tail light cluster causing the premature failure of it.I have seen the RECM fail before in the past needing replaced to correct this here.
The only way to be sure is to have a multi meter tapped in line with one signal at a time from the RECM so when it acts up you can catch the surge,this can be very difficult to do as we don't know which circuit for sure is at fault.
When you disconnected and reconnected the battery this reset the electronics in it and is most likely why it operated o.k. for a short time after this was done.
In some cases if you can pull it from the same year and model with all of the same options it may not need programmed at all but if it does unfortunately it has to be done by a dealer or authorized repair center that has access to programming.
I would assume the ground signal is o.k. as this is the same ground signal that feeds the left stop lamp and if you have had no issues with the stop lamp on the left side the ground is o.k.
The power feed signal comes in on the black wire with white stripe to feed the left hand tail light.This should have 12 volts dc with the light switch on.If it surges above 15 volts at any time this can damage the tail light and cause this here and would be the RECM at fault.
In theory yes you should be able to but my info isn't showing me if this will just plug and play for sure so there is a chance that it may need programmed as well.If it doesn't work when you install it then you would know that it needs programmed.
The only other thing I can think of that can cause this is a wiring fault from the rem to the cluster assembly or a connection fault at the rem or cluster assembly.
Below is a link to a diagram on this here.Unfortunately I am unable to blow it up any further myself but you want to test resistance of each wire from the control unit to the light assembly and from each wire to ground with the control unit and light assembly disconnected as well as from each wire to positive to make sure no wires are shorted to ground or voltage in any way.
