The quickest way to reset the 2013 Nissan Altima engine control unit (ECU) is to use a scan tool to facilitate the reset routine. Barring this, the next easiest way is to disconnect the battery, and then remove the fuse for the ECU. You'll want to disconnect the negative cable on the battery in the engine compartment, and then access the fuse panel nearby to find the relay for the ECU. When You've removed it, You should wait at least 10 minutes, and then plug the relay back in, and then hook the battery back up. Your ECU will have to relearn its performance settings, but should be clear of all prior DTCs.
