Flash reprogramming allows the Electronic Control Unit (ECU) software to be updated without replacing the ECU.
Read full bulletin
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.

In addition, some models may also utilize retainers for passenger side and rear seat floor mats. During Pre-Delivery Service (PDS), follow the appropriate Installation Procedure to attach the driver side, and if applicable, the passenger side and rear seat floor mats to the vehicle carpet using the floor mat retainers. If installation instructions are included in the floor mat kit, place the instructions in the vehicles glove box for customer reference.
A battery in a stored vehicle is subject to conditions that can reduce its performance and service life.
Read full bulletin
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. Electrified vehicles are equipped with two types of batteries, a High Voltage (HV) battery and a 12V battery. Conventional vehicles are equipped with only a 12V battery. As a matter of policy, Toyota does not provide battery warranty coverage for discharged and/or failed batteries due to lack of maintenance. It is the dealers responsibility to maintain the specified State-Of-Charge (SOC) of the vehicles battery while in stock and ensure proper SOC at delivery. To reduce customer service concerns due to an undercharged battery, ALL dealers should test the 12V battery and recharge, if necessary, no more than 48 hours before delivery to the customer.

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 Toyota. 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. (See PDS Check Sheet item 8 of Final Inspection and Cleaning.) This bulletin contains the PDS procedures that apply specifically to 2025 model year Crown vehicles. Refer to T-SB-0028-24, the universal Check Sheet that contains PDS steps that apply to all 2025 model year Toyota vehicles. To properly perform a complete PDS, you must complete all procedures contained in this TSB as well as the universal PDS Check Sheet. In addition, if the vehicle is stored for over 30 days, refer to T-SB-0023-24, Long-Term Vehicle Storage Guidelines.

rainwater, nighttime dew, or high humidity to form acidic compounds. If these contaminants settle and remain on a painted vehicle surface, especially the horizonal areas of the hood, roof, and decklid, significant damage can occur. This damage is the result of actual etching of the paint and appears as pitting or water spots. As acid rain droplets on the vehicle surface evaporate, the concentration strength of the acid increases, causing deeper and more rapid damage. This evaporation and corrosive action also occur more rapidly on dark colored cars as direct sun heat increases. It is the dealers responsibility to protect and maintain the quality of the vehicles paint finish after receipt at the dealership prior to the first sale. In areas known for high frequency and/or concentration of acid rain, frequent vehicle washing during high heat or humidity periods will minimize the potential for paint damage caused by acid rain. It is further recommended that either reverse osmosis or deionized water be used to prevent water spotting.

Body & Paint
4 bulletinsSome 2005 2026 Toyota vehicles that have undergone water intrusion may exhibit a condition in which a musty odor is present.
Read full bulletin
Follow the procedures in this bulletin to remediate the odor and address this condition. The purpose of this Service Bulletin is to provide general guidelines and procedures for odor remediation. This Service Bulletin provides a guide on how to prepare and treat the interior of the vehicle for odor remediation. Refer to the applicable model and model year Repair Manual and the EPA (Environmental Protection Agency) website for the most up-to-date safety and precautionary guidelines.
Acid rain results from rainwater or other airborne moisture that become acidic due to industrial chemical impurities in the atmosphere.

If these acidic compounds settle on an exposed vehicle, especially the horizontal areas such as the hood, roof, and decklid, significant damage to the painted surfaces can occur. Acid rain damage can typically be identified on vehicles by the presence of stains on the paint surface that resemble hard water spots. Unlike water spots however, acid rain damage cannot be removed by regular washing procedures. Also, because acid rain can etch and soften the paint, normal buffing or polishing repair procedures should not be attempted. This can cause further damage and result in visible depressions in the paint surface. The following are the three major categories of acid rain damage: Minor damage: requires only buffing to repair. Moderate damage: usually requires neutralizing, color sanding, and buffing. Severe damage: extending beyond 1/2 mil of clearcoat on a pearl, metallic, or solid color, requires neutralization, sanding, and repainting. In cases where acid rain damage is minor, neutralization and buffing with a liquid-type paint finessing product may provide an adequate repair. Only specially formulated products outlined in this bulletin should be used for that purpose. Unfortunately, other than minor damage, there is no simple method of determining the actual extent (depth) of acid penetration other than color sanding a representative affected area until there is no visible etching or depressions, followed by measuring the amount of paint removed with either a magnetic or digital-type film thickness gauge. The procedures in this bulletin are intended for use by qualified body/paint technicians and should not be attempted by inexperienced personnel. It is the dealers responsibility to protect and maintain the quality of the vehicles paint finish after receipt at the dealership prior to the first sale. Perform frequent vehicle washing, as often as daily, during high heat and humidity periods to minimize the potential for paint damage due to acid rain exposure. This is especially important in geographical areas known for high frequency and concentration of acid rain and industrial fallout.
Toyota vehicles are currently protected with RapgardTM protective film designed to protect the horizontal painted surfaces.

wheels, exposure to heavy machinery facilities, grinding, welding, etc. This type of contamination can be identified by the presence of small, red or brown particles on the paint surface. These particles are often difficult to see on dark color paints but can be easily felt when brushing a hand across horizontal body surfaces such as the hood, roof, or deck lid. Follow the Repair Procedure in this bulletin to clean vehicles that may have been subjected to contamination by airborne iron particles such as rail dust during rail transportation or extended storage near industrial areas.
