Service bulletins for the 2018 Toyota Sienna

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

The trail period of service is provided upon the vehicle purchase. Once the subscription has expired the DCM (Telematics Transceiver) will be in an inactive state. In some instances, a DCM may need to be replaced even though the customer is not using the service. If registration of the replacement DCM part is attempted using the Techstream utility after the account has become inactive, the registration will fail, and messages such as "ATX webserver is Down" or "ATX error" will be displayed.

TSB: REVISION NOTICE October 30, 2017 Rev1: * Applicability has been updated to include 2018 model year vehicles. SUPERSESSION NOTICE The information contained in this bulletin supersedes SB No. T-SB-0012-13. 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 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.

The summaries are NHTSA's. Each bulletin's page links NHTSA's copy of the manufacturer's document.
