Help -- Strange light!

Hello Guys
My Subura Impreza WRX STI Type-R has started to have one of the dash lights illuminated for 5/10 minutes when I start driving. It looks like, well, sort of looks like:

The great thing about a Japanese imported car is that, well, everything is in Japanese!!
Any suggestions as to what this means would be greatly appreciated.
Thanks for your help!
Steve.

On earlier WRX/STi models (up to part of the version IV production) a sensor was fitted after the primary cat.
This sensor detects failure of the primary cat and illuminates the light on the dash.
If it is coming on, your cat has probably failed. Cat failure is rare, but not unheard of. Had a 22B in the workshop in May, which had 600 miles on it. The owner was still very gently running it in, but had a buzzing/rattling coming from the rear (STi) silencer. I took the silencer off and gave it a shake. Out fell lumps of catalyst brick the size of golf *****. The brick had caught fire and melted.
There is wide variation between STi and 22B exhaust set ups, even for the same model and year. But this one only had a primary cat and no cat failure sensor.

Pete,
Are you saying that the Cats on Impreza's have ceramic substrates (the honeycomb material that the catalyst is actually on) ? I'd have throught that on the STi's / 22B's they have had a metal substrate as that can operate at higher temperatures. I could be wrong I'm going on info from 4-5 years ago!
cheers
Andy
