Did an alarm to an IS Lexus yesterday and had a problem. Dome light only comes on with ignition and have lost the key in ignition warning buzzer. I've checked all the fuses and had a look at the BCI box where everything seems intact. The dome light has RED / white as 12v+ and blue / YELLOW as the ground going feed.

Anyone come across this with an answer or suggestions? No my local Lexus dealer usually sends these problems to me!

Was there any reason to tag the key sence? (did you cut it with a t-tap lexus, dome light -- posted image.)  NOW THATS FUNNY.

Did you wire up domelight supervision? The dome doesn't come on with opening the doors?

When I started, domelight was working fine and door open warning worked on inst. panel. When finished domelight, clock and door open audible warning system don't work, except on ign. I've checked all the fuses had a quick look at steeering column, BCI box. It sounds like a fuse or a connector not "Rammed" home probably. These circuits are all lacking the permanent supply. Oh for a circuit diagramme so I at least know where to start.
