Hi, has anyone got the self-test procedure for the MFU please?

BTW, are there any other inputs for the interior light? mine registers all 4 doors plus the tailgate on the self test, but it thinks there is a door open somewhere permenantly. I have no interior light (timed out) and it will not run the rear wash wipe, even on self test.  If I pull the fuse and refit the interior light comes on for 30 minutes then goes out for good.

So, is there another input that could be shorting to ground?

Managed to work out what was wrong with the alarm, it was an aftermarket TOAD unit that had been fitted, disabling the original Central locking alarm.

That peice of tat is now in the bin, the alarm seems to work properly but both the MFU and the alarm unit think there is a door open somewhere even though the self test says all the door switches (inc boot) are working.

Update.  I discovered that the alarm was faulty, it was holding the interior light on until the relay timed out.  I replaced the alarm with another and all was fine.
