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.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11015498-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11015498-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11015498","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"LEXUS","model":"GX","year_from":2024,"year_to":2025,"match":"exact","vehicle_ids":["2024_lexus_gx","2025_lexus_gx"]},{"make":"LEXUS","model":"LS","year_from":2022,"year_to":2025,"match":"exact","vehicle_ids":["2022_lexus_ls","2023_lexus_ls","2024_lexus_ls","2025_lexus_ls"]},{"make":"LEXUS","model":"LS HYBRID","year_from":2022,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"LEXUS","model":"LX","year_from":2022,"year_to":2024,"match":"exact","vehicle_ids":["2022_lexus_lx","2023_lexus_lx","2024_lexus_lx"]},{"make":"LEXUS","model":"LX HYBRID","year_from":2025,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"LEXUS","model":"NX","year_from":2022,"year_to":2025,"match":"exact","vehicle_ids":["2022_lexus_nx","2023_lexus_nx","2024_lexus_nx","2025_lexus_nx"]},{"make":"LEXUS","model":"NX HYBRID","year_from":2022,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"LEXUS","model":"RX","year_from":2023,"year_to":2025,"match":"exact","vehicle_ids":["2023_lexus_rx","2024_lexus_rx","2025_lexus_rx"]},{"make":"LEXUS","model":"RX HYBRID","year_from":2023,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"LEXUS","model":"RZ","year_from":2023,"year_to":2025,"match":"exact","vehicle_ids":["2023_lexus_rz","2024_lexus_rz","2025_lexus_rz"]},{"make":"LEXUS","model":"TX","year_from":2024,"year_to":2025,"match":"exact","vehicle_ids":["2024_lexus_tx","2025_lexus_tx"]},{"make":"LEXUS","model":"TX HYBRID","year_from":2024,"year_to":2025,"match":null,"vehicle_ids":[]},{"make":"LEXUS","model":"UX HYBRID","year_from":2025,"year_to":2025,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
