Don't assume bad ECM with Nissan.

This bulletin applies to all 2009 and newer Nissan vehicles equipped with ASCD (automatic speed control device). Improper adjustment or operation of the ASCD brake switch can cause the automatic speed control device to not set and/or DTC P0605 to store in the ECM. If a malfunction in the ASCD system is detected, the “Cruise” indicator may stay on and the “Set” indicator may flash.

Before replacing the ECM for a DTC P0605, first check the ASCD brake switch for proper operation and adjustment.
