Numerous faults..

[LouRod]

Hi. 

I have a 16 plate diesel qashqai. Weeks ago it came up with multiple faults my sensors, camera, parking aren't working...the ABS light and multiple other dash board lights are on aswell as the start stop flashing.  I had similar with an old qashqai and we changed the battery and it fixed it. I've changed the battery and still can't reset the faults...there are now less faults since the new battery but there are still a lot showing up. 

Does anyone have any advice or help as to what it could be?

Thanks

Lou

It may be that the vehicle is not completely registering the new battery voltage

Maybe worth disconnecting the negative terminal and leaving off for a while to discharge the capacitive charge that is holding the memory and reconnect to reset the system.
It would obviously be easier to recode the battery with a scan tool which most garages should have

Also, check the earth leads on the underside of the engine and inner wings to ensure none of them are broken
