SummaryFlash 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 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 will initialize the flash reprogramming sequence. This bulletin also details the process for acquiring a Security Signature from TIS during the GTS+ ECU flash reprogramming process.

SummaryTSB: 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 in order to ensure proper operation and optimal battery life. As a matter of policy, Lexus does not provide battery warranty coverage for discharged and/or failed batteries due to lack of maintenance. It is the dealer?s responsibility to maintain the specified State-Of-Charge (SOC) of the vehicle?s battery while in stock and ensure proper SOC at delivery. To eliminate customer service concerns due to an undercharged battery during the first few weeks of ownership, ALL dealers should test the auxiliary (12V) battery and recharge, if necessary, no more than 48 hours before delivery to the customer.

SummaryTSB: 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. Follow the Tire Positioning Procedure in this bulletin to ensure that the original tires stay in the same location on the vehicle.

SummaryTSB: 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. 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 input their dealer information and set the service reminder on the Navigation Screen before delivery. By doing this, customers will be reminded to return to your dealership for service. (See Page 2 of the GX 550 PDS Check Sheet, ?Set Dealer and Service Reminder.?) This bulletin contains the PDS procedures that apply specifically to the 2024 model year GX 550. To properly perform a complete PDS, you must complete all procedures contained in this TSB as well as the GX 550 PDS Check Sheet. In addition, if the vehicle is stored for over 30 days, be sure to follow Long-Term Vehicle Storage Guidelines.
