Interesting..

Just the data I was looking for but couldn't get a response..

Going to leave it unlocked after tomorrow..condo is safe...

Having the battery load tested at my shop in the morning.....

They planted a worm in my brain about new battery failures that I need to relinquish!!!

Love the car sooo much......want to eliminate these issues ASAP...

As I stated my wifes epace is at 2,2 no warnings ..no issues.

BTW ..the XK never shows low battery just goes into the "blinking lights mode",

12.7V after overnight is great, doesn't sound like a bad battery (unless it's a tiny one i.e. wrong kind entirely).

Battery load test fine..

U0155-00 LOST COMMUNICATION WITH INSTRUMENT CLUSTER CONTROL MODULE

U3000-55. CONTROL MODULE

PERMANENT

had codes reset

been riding great...

Not sure what symptoms I should see


This was on the INTERGRATED CONTROL PANEL which I see as infotainment climate etc..

No issues in that area

PS:

No phone, heated seats, who needs that in Florida, and one speaker out.
