SummaryTSB: Some 2018 ? 2020 model year Lexus vehicles equipped with the Enform? 2.0 Navigation System require a Special Service Tool (SST) USB flash drive to update the map, points of interest, and system software. The SST is used with applicable vehicles to deliver the update; however, the process for generating license keys differs from previous generations. Before attempting to perform a map update, the head unit?s expiration date must be checked. If the expiration date is still valid, a license key may be generated without the use of an activation card number. Updating the maps without the use of an activation card number is considered an Embedded Navigation Update (refer to pg. 10) and performing this process does not extend the duration of telematic map services. If the head unit?s expiration date is expired or will expire within the next 90 days, it should be recommended to the customer to purchase an activation number. Utilizing an activation number will initiate a Dynamic Navigation Update (refer to pg. 4). This Dynamic Navigation Update will perform the Embedded Navigation Update and provide telematic map services for a period of two years from the day that the Dynamic Navigation Update is performed. Activation card numbers are provided in an activation card number pamphlet available through the normal parts ordering system.

SummaryTSB: SUPERSESSION NOTICE The information contained in this bulletin supersedes Service Bulletin Nos. ST004-01, SU001-08, and L-SB-0174-08. The aforementioned bulletins are obsolete, and any printed versions should be discarded. Be sure to review the entire content of this service bulletin before proceeding. This Service Bulletin provides best practice procedures for vehicle pulling complaint, diagnosis, and repair for 2002 ? 2021 model year Lexus vehicles. This information supplements Repair Manual procedures when the symptoms are: ?Vehicle Pulling: The vehicle moves to the right or left when the driver holds the steering wheel while driving straight ahead without exerting steering effort. ?Steering Wheel Off Center: The vehicle travels straight, but the steering wheel is not pointed straight ahead. The vehicle is not pulling. Before repairing a vehicle pulling to one side, it is necessary to clearly identify the cause of the pulling condition. Frequently, pulling to one side is diagnosed as a wheel alignment concern. However, the actual cause may be related to the lateral force generated by the tires, vehicle damage, road crown or worn components. Performing a wheel alignment when tire force is the cause could result in the wheel alignment being set at a value outside of specifications. This could then cause other problems such as uneven tire wear, etc. A customer may notice a pull to the left when in the left lanes of travel and notice a pull to the right or no pull when traveling in the right lanes of travel on the very same section of roadway. This road crown effect is environmental and cannot be corrected with suspension adjustments or any other wheel or tire modification discussed in this bulletin.
