Default question about specific cluster lights

I have two lights in my cluster that I don't know what they do or light up under what circumstances.

1- ''CAT'' does it light up when the cat converters are too hot ?

2- immobilizer/security... no idea when it should light up

Default Cat/immo

CAT= Catalyst Warning System, Used for P04XX codes dealing with the catalytic converters or O2 sensors.
Security/IMMO is for the immobilizer. If you try and start the car with a key that is not registered with the IMMO box, ecu, or cluster the car will shut down after 2 sec and the light will flash. This light should come on for about 1 sec and turn off after a registered key is inserted into the IGN and turned to the on position.
