INTRODUCTION Nissan is conducting this voluntary safety recall campaign, on certain specific model year 2023 LEAF vehicles, to inspect and, if necessary, replace the front passenger (RH) side brake tube. This service will be performed at no charge to the customer for parts or labor. IDENTIFICATION NUMBER Nissan has assigned identification number PC976 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. 2/8 NTB23-045 SERVICE PROCEDURE Front Passenger Brake Tube Inspection 1.

Front passenger brake tube Pinch Gouge 4/8 NTB23-045 Front Passenger Brake Tube Replacement To avoid the risk of death or severe personal injury:  Do not allow the reservoir tank to empty, as this may cause damage to the master cylinder internal components or the brake system.  Do not allow foreign matter (e.g. dust and oils other than brake fluid) to enter the ABS Actuator or Master Cylinder reservoir tank. To avoid damage to the vehicle:  Do not spill or splash brake fluid on painted surfaces. Brake fluid may seriously damage paint. Wipe it off immediately and wash with water if it gets on a painted surface.  Do not depress brake pedal while removing the brake hose or brake tube. If this is not complied with, brake fluid may splash.  If the brake fluid or grease adheres to the disc rotor, quickly wipe it off.  All hoses and piping (tubes) must be free from excessive bending, twisting, and pulling.  Make sure there is no interference with other parts when turning steering both clockwise and counterclockwise.
