I think he wants something like this what I found on a forum for an Infinity, but with the complete process:
"So last night I experimented to see if I could use 1) the ODB3 method to reset and put the tpms into learning mode with 2) the method described in the service manual to activate the wheel sensors without an activation tool.
It worked... after a little experimenting. The steps I used to register my winter wheel sensors were:
1) set different tire pressures in each wheel: RF to 34psi, LF to 31psi, LR to 28 psi and RR to 26psi;
2) start engine;
3) perform the OBD3 procedure to reset and put the tpms into learning mode - tpms warning light should be blinking;
4) drive vehicle around at speeds greater than 40kph until the tpms warning light stops blinking and turns off. Note a short time later, the tpms warning light should go on and stay on (since one or more of your wheels will be lower that 28psi);
5) disconnect the wire from the connector; and
6) reinflate the tire pressure to spec. and drive around until the tpms warning light turns off."
I have not found anything for our Altima's, but Google brings up a lot of hits....
