You can, but this will just give you a confirmation that the relearn was successful. If you do it without TechII you don't know if it worked or not. You will only know if you get a DTC later down the road, usually P0303 which is not relevant, just the code put because ECM doesn't know what's going on, since P0303 is a cylinder misfire number 3 with no read error. Then you might have to do a CPS relearn again.
