Engine Control Module (ECM) Reprogram
Voluntary Service Campaign
***** Campaign Summary*****
Nissan has reclassified the previously announced quality action (PC945) for new vehicle inventory as
a Voluntary Service Campaign to update the Engine Control Module (ECM) software. The â??idle air
volumeâ?? and â??airflow lower limit value for alternator load correctionâ?? parameters were changed for
model year 20 vehicles.
These Engine Control Module (ECM) calibration changes may affect alternator control and idle speed
control optimization, which could, under certain conditions, cause the engine to stall when coming to
a stop.
