Service bulletins for the 2012 Lexus LFA

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

L-SB-0083-13 Rev2017-08-14. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; EQUIPMENT:ELECTRICAL:NAVIGATIONAL SYSTEM(GLOBAL POSITIONING SYSTEM). LSB: Lexus models equipped with Hard Disk Drive (HDD) Navigation require a Special Service Tool and follow a unique process for updating map, points of interest, and system software. Instead of individual DVDs installed into the vehicle, all Map Data is uploaded directly to the HDD system. Map Data will be released annually through direct shipment of tow Map Data DVDs to each dealership service manager. The annual Map Data release must then be installed onto the Navigation Update Tool. Individual map updates are then loaded into the vehicles with special map security keys. These keys are available through the normal parts ordering system. Keys are loaded onto the Navigation Update Tool through a PC or Techstream unit using software found on the Technical Information System (TIS). Follow the procedures listed in this bulletin to: Identify the current version of Map Data on the vehicle and on the Navigation Update Tool, Load Map Data onto the Navigation Update Tool, Load map security key(s) onto the Navigation Update Tool, and Connect the Navigation Update Tool to the vehicle and update the Map/System Data to the latest version.
