NTB24-0342024-07-10. Service bulletin. ELECTRICAL SYSTEM; BACK OVER PREVENTION: WARNINGS. VOLUNTARY SAFETY RECALL CAMPAIGN 2018-2022 LEAF; REAR CAMERA CAMPAIGN ID #: R23D7 APPLIED VEHICLES: 2018-2022 LEAF (ZE1) Check Service COMM or Dealer Business Systems (DBS) National Service History to confirm campaign eligibility. INTRODUCTION Nissan is conducting this voluntary safety recall campaign on certain specific model year 2018-2022 LEAF vehicles to inspect the rear camera operation and either add support to the rear camera harness or, if necessary, replace the rear camera. This service will be performed at no charge to the customer for parts or labor. IDENTIFICATION NUMBER Nissan has assigned identification number R23D7 to this campaign. This number must appear on all communication and documentation of any nature dealing with this campaign. DEALER RESPONSIBILITY It is the dealer’s responsibility to check Service COMM or Dealer Business Systems (DBS) National Service History for the campaign status on each vehicle falling within the range of this voluntary safety recall which for any reason enters the service department. This includes vehicles purchased from private parties or presented by transient (tourist) owners and vehicles in a dealer’s inventory. Federal law requires that new vehicles in dealer inventory which are the subject of a safety recall must be corrected prior to sale. Failure to do so can result in civil penalties by the National Highway Traffic Safety Administration. While federal law applies only to new vehicles, Nissan strongly encourages dealers to correct any used vehicles in their inventory before they are retailed.

NTB23-0492023-07-11. Service bulletin. ELECTRICAL SYSTEM. 12 VOLT BATTERY TESTING FOR IN-SERVICE VEHICLES SERVICE INFORMATION The following Service Information lists NNA 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/
