Code E051: Mem-Cal Error

Checks that all pins are fully inserted in socket. If okay, replace PROM, clear memory and recheck. If Code E051 reappears, replace ECM.

CAUTION: To prevent possible electrostatic discharge damage, DO NOT touch ECM connector pins or soldered components on ECM circuit board. When handling MEM-CAL, DO NOT touch component leads. DO NOT remove integrated circuit from carrier.
