procedural recommendations for establishing good connections while performing 12V battery testing. These recommendations are expected to promote uniformity during the connection process, therefore reducing the number of incorrect Test with DCA and Replace results. HINT: If 12 volt batteries are allowed to discharge for a prolonged period of time, battery life may be drastically reduced. This condition may lead to premature battery replacement and customer dissatisfaction. IMPORTANT: CPX-900 is now an accepted testing tool to use along with or in place of the DSS-5000 CPX-900 operating instructions are found at: https://nissancpx900.midtronics.com/ DSS-5000 operating instructions are found at: https://nissandss5000.midtronics.com/ DCA-8000 is now a required testing tool to be used for all warranty replacement decisions. The DCA-8000 is also a more efficient charger than previously available, and will charge any available 12 volt lead acid battery safely and accurately as long as all precautions and inputs are made correctly. The DCA-8000 operating instructions are found at: https://nissandca8000.midtronics.com/

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.

The essential tool (part number # J-52982, Figure 1) required to remove the nut staking, is called out as a Cape Chisel in the Electronic Service Manual (ESM), and must be used to prevent thread damage to the axle (see Figure 2 on page 2). The Cape Chisel arrived at dealers in December of 2020. Damaged threads, due to improper removal of the stake placed in the nut, will not be covered by warranty. For information on using the Cape Chisel, refer to the Electronic Service Manual (ESM): Section TRANSMISSION & DRIVELINE > FRONT AXLE > REMOVAL AND INSTALLATION > FRONT DRIVE SHAFT > LH/RH.
