Flash calibration updates for specific vehicle models/ECUs are released as field-fix procedures described in individual Service Bulletins. This bulletin details the Techstream ECU flash reprogramming process and outlines use of the Technical Information System (TIS) and the Calibration Update Wizard (CUW). Flash calibration updates can only be applied to the vehicle/ECU combination for which they are intended. ECUs have internal security that will not allow them to be programmed with another ECU?s information. NOTE ECU is a Toyota term used to describe integrated computerized devices responsible for managing the operation of a system or subsystem. For the purposes of this bulletin, the term ?ECU? is used as a generic label for the following SAE J1930 standard references: ? Powertrain Control Module (PCM) ? Engine Control Module (ECM) ? Transmission Control Module (TCM) ? Any other Toyota specific control unit

May 08, 2018 Rev1: * Applicability has been updated to include 2019 model year Toyota vehicles. Any previous printed versions of this bulletin should be discarded. Hybrid vehicles are equipped with two types of batteries: * Hybrid Vehicle (HV) battery - Auxiliary (12V) battery If the hybrid vehicle is put into storage, the State-Of-Charge (SOC) of its HV battery and auxiliary battery will gradually decrease. To prevent the auxiliary battery from becoming discharged during storage, proper maintenance is necessary. Perform the following maintenance service for the HV battery and auxiliary battery. NOTE - BEFORE disconnecting the auxiliary battery, confirm the shift lever is in the "P" position and apply the parking brake completely. The shift lever CANNOT be shifted from the "P" position with the auxiliary battery disconnected. * If the negative (-) terminal of the auxiliary battery is reconnected, even if the power button is in the Start mode, the hybrid system may NOT start. In this case, push the Power button and select the Start mode again to start the hybrid system (the Ready light is ON). If the hybrid system still does NOT start (the Ready light is OFF), refer to the Repair Manual.

T-SB-0229-12_Rev2018-04-23. Service bulletin. ELECTRICAL SYSTEM. TSB: REVISION NOTICE November 22, 2017 Rev1: ? Applicability has been updated to include 2014 ? 2018 model year vehicles. Any previous printed versions of this bulletin should be discarded. In the event that a Toyota vehicle becomes submerged in water, many components may be physically damaged. Electrical and electronic components, including wiring harnesses, are particularly susceptible to corrosion and subsequent malfunction. Although any flooding can be damaging, salt water flooding elevates the potential for abnormal conditions and may increase risks due to its highly corrosive and conductive nature. Salt residue also continues to corrode and remain conductive even after a vehicle dries. This bulletin is intended to assist with safe handling and inspection of flood damaged vehicles and to provide basic guidance on likely needed repairs.
T-SB-0195-172018-04-02. Service bulletin. ELECTRICAL SYSTEM. TSB: A battery in a stored vehicle is subject to conditions that can reduce its performance and 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, Toyota does not provide battery warranty coverage for discharges and/or failed batteries due to lack of maintenance. It is the dealer's responsibility to maintain the specific State-Of-Charge (SOC) of the vehicle's battery while in stock and assure proper SOC at delivery.
