So I bought this 05 jaguar s-type 4.2L v8, the kid before me ran it for 9 months with no oil and locked up the engine, well I found another engine and swaped it out, car runs fine but there are quite a few electronic issues like when I open the door all locks besides the tuck just lock and unlock 10-15 times and then stops, I think this is cause the door lock actuator is broken, also my screen on my dash would sometimes illuminate but be blank but everything would still work, today I get in and the doors start unlocking and locking then after about 3 times just stops skips 1 lock and unlock then continues... my dash would normally be blank for 1 out of like 20 drives, it's been blank for the past 8 wich is concerning. Now there is the small yellowish/ orange light on the dash is on and when I try to move the car it starts beeping really loud, turn signals will turn on stay on and then turn of but won't blink, the memory settings where glitching when getting in, and the car won't show annything on the scanner besides the engine controll model... all the electronics are glitching and idk what to do, I've already disconnected the battery, reconnected it and still nothing, checked fuses and from what I can tell they are all good

 

You need to understand that with all the problems you have that a standard scanner will be of no value?
I am a bit of a broken record here but with the number of problems you have the only diagnostic system will be the factory Jaguar setup called SDD.

This is NOT released to the public and we are NOT suppose to be using it. So no instructions on anything and all my learning has been from others on this forum and ACTUALLY using the system! There is no replacement for hands on experience.
Can you do this? If you swapped the engine yourself then yes you can but it will take some time and study to get there.

This forum has a ton of threads if you search so get ready for a head ache reading all this!

+1 on using SDD whenever possible.

Whenever beginning any electrical diagnosis, start with verifying the available battery voltage. Measure the voltage across the battery terminals with a voltmeter when the ignition is in the OFF position. There should be a minimum of 12.6 volts. If not, charge the battery for five hours at 2 to 5 amps and retest.
