codes, a description of the error condition, and the action required to
resolve the error condition.
In each case, the Recommended Action column lists steps necessary to
correct the problem.
program to verify whether the condition has been corrected. If the error
code reappears, perform the next step, then run the diagnostics program
again. Follow this procedure until the diagnostics program no longer
detects an error condition.

YY = test or action that failed
