Code 51: MEMCAL Error

Check that all pins are fully inserted in ECM socket. If okay, replace MEMCAL. Clear memory and recheck for Code 51. If code reappears, replace ECM.

CAUTION: To prevent possible electrostatic discharge damage to ECM or MEMCAL, do not touch component leads. Do not remove integrated circuit from carrier. See the CCC COMPONENT R & I article in this section.
