The diagnostics runs two different tests. The first series of tests is done with
the pump and heaters off. If failures are detected be sure to note the type
and the reading.
After a short time the computer will prompt to start the second series of
tests. Again, note the type and readings associated with any failures. This
information will assist the service department in diagnosing any problems.
