The error messages in table 4-3 are used by factory technicians in determining what actions may have
preceded a system failure. These messages do not necessarily indicate a current system failure and are
provided for information only. Should the installer observe these messages in the error log without a
SKY497 Failed message during normal operation, no service action is required.
