Interior lights flash when locking/unlocking

[clemenshess97]

Hey everyone,

I just bought a 03 Tahoe with some minor problems, one of them is the interior lights flashing when I hit the lock or unlock button on the key fob.
In the DIC I selected the exterior lights to be flashing when I lock or unlock the truck, I wish I could choose the horn to honk as well, but my truck was first delivered to Italy and I think they deactivated the honk option for european trucks.

Does anyone had this problem before with the interior lights flashing when locking/unlocking ?

I know, but I can´t even choose the honk option in the DIC. Because it's a european model, GM deactivated this option.

is the fob oem or does it have some kind of aftermarket alarm system installed? maybe a previous owner wired the lights that way, check the drivers footwell junction box and see if there are any wires added that are not factory.

Sorry, but I am at a loss about this. @Doubeleive is likely on a better assist path than I would be.

the fob is OEM and the alarm system is original.

I thought maybe the BCM is faulty ?
