So seems as if i have some electric issue maybe battery ,maybe alternator but i do not know where to start had the best indy shop in my area test the battery and it checks out fine but this happens and after it come back up i no longer can use the parking assist system no sensors or lights. Overtime i had random blind spot system not available but they normally went away now when i get the warning the next thing that happens is TPMS not available then a loud beep and then the info entertainment system goes black, i then lose controls to the windows door locks and not light near the speedometer for turn indicators even tho they are actually working. PLEASE HELP

 

I had much the same problem and it turned out to be a battery fault hope this helps

 

First tell us the car and other details?
How old is the battery?
Have you replaced the battery ?

Sorry not much help.

Ok, your profile says you have a 2013 XJ, but your videos of the center screen show that the right end button under the display is a power button and not a ECO button. So I must conclude your XJ is 2012 or earlier as you didn't tell us what year and model you have. As i have a 3012 with a second ECO battery I cannot aid you with your issue. If you added a signature to your profile then whenever you asked for assistance members would find it easier to offer solutions. No issue just saying a signature can go a long way.

 

 

Hi Robert,
I'm correcting your typo so others aren't confused. I know that you have a 2013.

I doubt they tested the battery properly and based on your issues sounds like a battery to me. You can have 12.6volts and low or no cold crankingg amps. All modern heavy electronic cars need a absolutly strong good battery. To really test you have to measure ccs and reserve capacity ah(amp hours) if either are low replace the battery and reset the battery monitor with sdd so you have proper charging operation

 

 

What does it say when the car is running?

Do you have a meter you could use while it's running?

i do not have a meter myself to test when running any suggestions i just ran an engineering diagnostic again after a power down after the system went out and today it shows 12.4 local so i am really leaning towards a battery swap before i kick out 600$ to Jaguar of Annapolis for an electric diagnosis were they check all wiring

 

Do you know when your battery was installed? If not, buy a new one and make sure that it is fully charged before it's installed. Many brand new batteries sit on the retailer's shelves discharging for months. Also buy a CTEK MUS4.3 battery maintainer and use it daily to keep your new battery fully charged. Lots of threads on this Forum.
