Does anyone know how long the slabs timer runs when the ign is turned off??

To clarify I had a flat battery. I thought Id do a drain check and found that after turnining everything off there was a current draw of around 1/2 an amp.
I've traced this to fuse 11 (30amp) in the engine bay. Remove the fuse and the draw is gone. Replace the fuse and there is no draw. Turn ign on and off and the draw is back until you pull the fuse again .
I THINK? that the slabs unit must have a built in timer ( for a set time after the engine turned off) to allow the vehicle to self level after say the boot has been unload. But how long is it live for??
It (the current draw) was gone by the time i'd had my tea so it does turn off evenyually.
Anyone?? Oh and it looks like my battery is fubared,

Thanks

Mine is about 20 mins then SLABS goes to sleep.

it's described in te WSM:
The ECU incorporates a counter which times the operation of the SLS system and prevents the compressor
exceeding its duty cycle. The ECU can remain powered for up to 1.5 hours after ignition off is sensed to allow the
counter to continue running to avoid an ignition cycle resetting the counter.
Opening any of the doors will power up the ECU, irrespective of ignition switch position. The door open signal is
sensed by the door switch completing an earth path which is sensed by the ECU. The ECU cannot differentiate
between any of the doors. The door open signal powers the ECU for up to 30 minutes to allow the vehicle to re-level
when a load is removed or passengers leave the vehicle.

Best way to measure drain is after the Slabs is off, either leave bonnet open or tape bonnet switch down so it doesnt pick up signal when it’s opened.
My D2 was hard on my battery without it being a proper drain. So i hard wired in a solar maintainer and now its fine.

The bonnet switch is not involved in the SLABS circuit at all, only the door switches but the bonnet must be left open as to not have to open a door to open the bonnet cos the door will activate the ECU
