I have a 2007 L322 3.6 diesel, and the airbag light goes off after a few seconds, and then comes back on and stays on.
My iCarsoft is not showing any DTC's, and my mechanics diagnostic is showing 'resistor 12', voltage too high. Anyone know where resistor 12 is located?

If it's usual LR design, then nowhere near resistor-11 & resistor-13.

Mine used to do that regularly and diagnostics always said battery disconnect module. Cleaning the rusty nut seemed to clear it.

TBH, it sounds like some Chinglish translation of a DTC description. For the SRS light to be illuminated, there either has to be a DTC set or an internal defect in the module.

I don't think a 2007 L322 had a battery disconnect module, mine didn't anyway...

When I put my iCarsoft on it first, I think there was/were code(s). I'll hook it up again tomorrow and see if I can replicate it. If not, it's looking like checking under seat connections.

Thanks, but mine doesn't have this nut, although it does have the wire coming out of the loom and connecting to the positive terminal.

Try sitting on each seat in turn jump up and down in the seat.....seriously you mite feel a fool but it sometimes works. Without a gap tool you will not be able to turn it off but as you say "it goes off then on" try the seat trick

Going off then on sounds like it's failing a self test.. ie.. comes on to do a bulb check.. good off then decides there is a fault so comes back on
