IT means the radio - the blank box, the "Head unit" for audio - behind those buttons on the console panel - is not communicating.
Lighting sequence - then the radio is supposed to establish connection via a communication cable - but it fails, so the APIM (Sync) powers it back off and so nothing.
So, it means the Audio amp head unit needs to be serviced - or just replaced. Similar year, else the WHOLE APIM/Audio unit to get radio back if you can't find a head unit that works for that Date Code printed on the Head Unit once you get it out of there to inspect it.
