Flash reprogramming allows the Electronic Control Unit (ECU) software to be updated without replacing the ECU. Flash calibration updates for specific vehicle models/ECUs are released as field-fix procedures described in individual Service Bulletins. This bulletin details the Global Techstream+ (GTS+) ECU flash reprogramming procedures and outlines the use of the Technical Information System (TIS) and the Calibration Update Wizard+ (CUW+). To ensure the correct ECU software is installed, ECUs will require a Security Signature before the ECU initializes the flash reprogramming sequence.

Pre-Delivery Service (PDS) is a critical step in satisfying our new car customers. Customer feedback indicates the following areas deserve special attention when performing PDS: •Careful inspection for paint chips/scratches and body dents/dings. •Proper operation of electrical accessories (including interior light, clock, and radio reset). •Interior cleanliness. •Proper function of mechanical systems. The PDS process helps identify potential vehicle concerns before customer delivery. After completing the PDS process, maintain accurate PDS records by ensuring the required documents listed below are completed and recorded in accordance with Lexus Warranty Policy. •GTS+ Health Check •Completed PDS Check Sheet •Battery Charge Test Print Out •GTS+ Tire Pressure Information Customer retention and proper maintenance of vehicles are and have always been a major focus for Lexus. To help remind customers that regular service is essential to the proper maintenance of the vehicle, dealers are required to install a service reminder sticker before delivery. By doing this, customers will be reminded to return to your dealership for service. Your current service reminder sticker may be used. This bulletin contains the PDS procedures that apply specifically to 2027 model year IS 350 vehicles.
A battery in a stored vehicle is subject to conditions that can reduce its performance and service life. These conditions include storage period, temperature, parasitic drain, and battery load. Because of these factors, battery inspection and maintenance are required to ensure proper operation and optimal battery life.
Long-term or off-site storage requires special care to maintain vehicle condition. The following guidelines should be implemented to minimize vehicle component/part degradation due to extended vehicle storage conditions. Long-term storage can affect a vehicle’s systems and components. Any problems that are found should be corrected immediately.

During the manufacturing process, tires are mounted on the vehicle as matched sets to help reduce conditions such as pulling or drifting. If the wheels are replaced or refinished before vehicle delivery, it is important that the tires remain on the vehicle in the same location and in the same direction of rotation.
Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
