Engine troubleshooting charts
You can use Table 5 to find solutions to problems that have the described
symptoms.
If you cannot find the problem in the table, go to “Starting the diagnostic programs”
on page 98 to test the appliance. If you have run the diagnostic test programs or if
running the tests does not reveal the problem, call for service.
The symptom appears in the left column of the table. Instructions and probable
solutions to the problem are in the right column. If you have just added new
software or a new option and your appliance is not working, do the following before
using the troubleshooting charts:
v Remove the software or device that you just added.
v Run the diagnostic tests to determine if your appliance is running correctly.
v Reinstall the new software or new device.
