Hi,
I don't have the service manual for this model, but I did locate the tech. data sheet, I'm attaching it below. There is no service test 46. There is a STEP 46 in the tech. data sheet, but activates the water dispenser, not the ice maker.
If the ice maker is not working, it sounds like you may have broken wires. This has been very common on this model.
Lots of members have found frayed and broken wires causing the ice maker/and or auger motor to be dead. Remove your bottom kickplate grille,
Remove the black wire harness loom too, broken wires can be underneath it.
Another member was having a similar problem here:
FIXED: GSF26C4EXY02 Whirlpool Gold Ice Maker Problem Look at his post #6 he found
frayed and broken wires underneath the freezer door, remove your kickplate and check for that first.
Here's another one with the same thing about the frayed and broken wires:

If the wires are good, then you'll need a new ice maker.
Here's the ice maker for your model:

Let us know what you find.
