Audio Control Unit Reprogram
Dealer Inventory
*****Dealer Announcement*****
Nissan is conducting a quality action to reprogram the Advanced In Vehicle Infotainment (AIVI)
control unit with updated software on 6,519 specific model year 2021 Nissan Sentra vehicles. Due
to a program logic concern, the audio system does not sleep after receiving a message to ‘Go to
Sleep’ from the Body Control Module (BCM). As a result, the standby current becomes high
causing the battery capacity to be gradually discharged, which may result in the customer
unable to start the vehicle.
Affected vehicles are subject to stop sale and are either currently in dealer inventory or assigned
and in transit to the dealer.
*****What Dealers Should Do*****
PLEASE FOLLOW THE ATTACHED INSPECTION INSTRUCTIONS:
1. Verify if vehicles are affected by this quality action using Service Comm or DBS National
Service History – Open Campaigns I.D. PM984
• New vehicles in dealer inventory can also be identified using DBS (Sales-> Vehicle
Inventory, and filter by Open Campaign).
 Refer to NPSB 15-460 for additional information
• Please continue to check newly arriving inventory for campaign applicability.
2. Please do not drive, loan, sell or trade the specific vehicles in dealer inventory subject to
this quality action.
3. Dealer must use the attached procedure to update the software for any vehicles affected
by this quality action.
4. The service department should submit the applicable warranty claim for the action
performed to close the campaign on Service Comm and release the vehicle.
