Renault midlum warning light defect 92

Hi all.
I’ve got a bit of a head scratching problem with Renault midlum I’ve got in workshop
The first complaint was that the word stop came up on dash.Then when driver switched it off and took key out the dash stayed powered up with a picture of battery on screen and under that kept flashing up defect 92 and then theft detect.I plugged into our diagnostics and had a couple of codes for injectors.i cleared faults but problem is still there.Wondering is this a common problem or if anyone has any ideas.Its a 2005 which I forgot to mention.Thanks in advance.

It’s French.
It’s 10 years old.
It’s electrics have expired.
:wink:

Sorry, not much use to help you diagnose and repair, but pretty accurate I’d say…

Its time to get a new big van pal,it would work out cheaper and less hassle :wink:
