Here is the updated fast track for your model. This one was put out about 12 months after the one you have.
"EEPROM Clear Check
Power off, Press Delay Start, Signal and Power Key at the same time. Good = Good Fail = FAiL
All memory will be cleared, including Fault Codes
This should be done when a new Main PCB is installed"
I noticed this was added to the revised fast track.
