Audio Control Unit Reprogram
Voluntary Service Campaign
Dealer Announcement:
Nissan has reclassified the previously announced quality action (PM984) for new vehicle inventory as a Voluntary Service Campaign to reprogram the Audio Control Unit on 17,171 specific 2021 Sentra vehicles identified in Service Comm and DBS National Service History.
Due to a program logic concern, certain vehicles may have been manufactured with an Alliance In-Vehicle Infotainment (AIVI) system software that allows the AIVI system to continue drawing current after the vehicle is shut off. This event may occur when the operator turns off the ignition followed by some operation (i.e. brake pedal pressed, door locked, etc.). These types of sequences causes the AIVI system to “wake up†and the system will not return to “sleep†mode until another ignition on-off cycle occurs. If this event occurs, the customer may experience a discharged battery and if the vehicle is not restarted within 46 hours, the battery may completely discharge resulting in a no start condition.
Affected vehicles are not subject to stop sale and are either currently in dealer inventory or assigned and in transit to the dealer.
What Dealers Should Do:
1. Verify if vehicles are affected by this Voluntary Service Campaign using Service Comm or DBS National Service History – Open Campaigns I.D. PM991.
2. Dealers are requested to remedy any affected vehicles in dealer new or pre-owned inventory to ensure customer satisfaction.
• New vehicles in dealer inventory can also be identified using DBS (Sales-> Vehicle Inventory, and filter by Open Campaign).
 Refer to NPSB15-460 for additional information
3. Dealers should use NTB21-066 to correct any vehicles subject to this campaign.
