control valves (valve bodies) now come with blank Transmission Control Modules (TCMs). Blank TCMs come without software and must be programmed (not reprogrammed) and then configured after they are installed. When ordering a replacement A/T or control valve, use the Nissan electronic parts information systems to obtain the correct software program part number See this bulletin for further detail.

ACTION Use a punch to seat the block ball plug in the hole (refer to the Service Procedure). NOTE - Do not replace the engine block for this incident if it should occur. See this bulletin for further detail.

calculated prior to State emissions testing (also known as Inspection Maintainence, I/M, or SMOG testing depending upon location). Allowing the vehicle to idle for 22 minutes will allow for faster CVN calculation. It is recommended that customers utilize this method if the vehicle needs to be tested for emissions soon after ECM reprogramming. See this bulletin for further detail.

attempting any repair: * Check for stored DTCs. * Check if the driver is resting their left foot on the brake pedal while accelerating. Advise the customer not to rest their foot on the brake while accelerating. * Use CONSULT-III plus in Engine Data Monitor to check operation of the brake lamp circuit signal. Monitor the brake switch during the incident; it should be "OFF". Please see this bulletn for further details.

* The valve stem length of both intake and exhaust valve has been increased (Figure 1) and are a direct replacement for the shorter style valve. * The related valve lifter cup has been shortened (Figure 2) and the point at which the valve lifter contacts the valve stem has been shortened (not shown). These service parts will require that the valve and valve lifter be replaced at the same time. See this bulletin for further details.

Blank ECMs come without software and must be programmed (not reprogrammed) before they will function. See this bulletin for further detail.

- The SRT is used to indicate whether the engine control module (ECM) has completed self diagnosis of major emissions systems and components. - In these instances the State may require completion of the SRT before permitting the emissions inspection to proceed. Refer to this Bulletin for further details.

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/

sonar activates with no obstacle ahead), inspect the front license plate, front license plate frame and if equipped, the front license plate bracket. See page 2 for example photos. The front sonar parking sensor may activate if the front license plate is bent outward from its bracket (there is a gap between the license plate and the bracket) OR the front license plate frame is bent or loose and is hanging outward, away from the license plate and/or bracket (there is a gap between the license plate frame and the license plate and/or bracket) OR the bracket is loose and is hanging outward, away from the bumper (there is a gap between the bracket and the bumper). If any of these conditions are found, correct it by removing the gap (straighten the license plate, straighten and/or secure the license plate frame, or secure the bracket, as it applies). - Retest the operation of the front sonar parking sensor. If the issue is not resolved, go to ASIST and the related Electronic Service Manual (ESM) for further diagnosis. See this bulletin for further detail.

In an effort to protect the paint finish, Paint Guard Film (PGF) is applied on many new Nissan vehicles. Paint Guard Film is a temporary white plastic protective film that is applied by the factory to the horizontal painted surfaces of the vehicle. The PGF protects the paint finish during vehicle handling, transportation and storage from harmful elements such as acid rain, iron particles, bird droppings, tree sap and other environmental contaminants. NOTE - Paint Guard Film CANNOT remain on the vehicle for more than six months after the vehicle's manufacture date. PGF must be removed at the end of six months.

INTRODUCTION Nissan is conducting this voluntary safety recall campaign on certain specific model year 2004-2012 Armada, 2004-2012 Titan, and 2004-2009 Quest vehicles, to inspect and if necessary, replace the driver Air Bag Cover. This service will be performed at no charge to the customer for parts or labor. IDENTIFICATION NUMBER Nissan has assigned identification numbers PC944, PC946, PC947 and PC949 to this campaign. The vehicle specific number must appear on all communication and documentation of any nature dealing with this campaign. DEALER RESPONSIBILITY It is the dealers 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 dealers 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. This bulletin has been amended. See AMENDMENT HISTORY on the last page. Please discard previous versions of this bulletin.
