  Summary

  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 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.

  Summary

  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 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 Grand Highlander and Grand Highlander Hybrid 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.
