Code 81 how do i clear it off

[dqydj]

81 engine code CRC failure

this is from the manual-
this error displays when the microcode to be
progammed in the engine flash code module has
failed a CRC check. Press Go to clear the
message. The microcode data is discarded and
must be re-transmitted from the host computer.

hope this helps.
