SummarySome 2022 – 2024 model year NX 250 and NX 350, and 2023 – 2024 model year RX 350 vehicles may exhibit both of the following conditions at vehicle startup: •A “Shift System Malfunction” message on the Multi-information Display (MID), as shown below. •Battery voltage drops below 10V. These conditions are more likely to occur when the outside temperatures are near freezing. The Engine Control Module (ECM) (SAE term: Powertrain Control Module/PCM) logic has been modified to reduce the possibility of these conditions.

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.
