Code P1623, Prom Error

Check that PROM is correctly inserted in the socket. If okay, replace PROM, clear memory and recheck. If Code P1623 reappears, replace PCM.

NOTE: To prevent possible electrostatic discharge damage to PCM or PROM, DO NOT touch component leads. DO NOT remove integrated circuit from carrier.
