The 'key-on/key-off' 3 times cycle does not work on my 05 GC. Is there any way to retrieve codes without a scan tool?

When I first tried on my '02 it took several tries to get the timing down..... give it a few more tries.
Retrieving codes: Turn the ignition key until the digital odometer displays, repeat three times in succession and then back to "On" (On/Off, On/Off, On/Off, On). At the fourth "On" the odometer will be replaced with codes. If no codes are present then "Done" will appear.
My scan tool doesn't work...apparently it needs a software upgrade. cal
