While obtaining the fault code you don't hold anything. Holding the odometer button in while turning the key only performs a test of all the dials in the guages.

Turn the key on and off 3 times within 5 seconds and at the third turn leave the key pointing towards the windshield. If you do it right, it will either say "done" or give you a fault code like the ones listed.
