1990 Vette code 12 flashing

I recently purchased a 1990 Corvette after being without a Vette and off the forum for several years, and it has a couple of problems.

The service engine soon light flashes code 12 continuously when the ignition is on and engine not started. I know it is supposed to flash three times, then any fault code three times, then 12 three times again. Also. when the engine is running, it flashes continuously.

Second problem, a light above the service engine light stays on which reads:
I have no idea what this means. Any info to help me clear these lights would be greatly appreciated.

Thank you
