Service bulletins for the 2017 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.

| T-SB-0001-18_Rev | 2018-04-02. Service bulletin. ELECTRICAL SYSTEM. TSB: REVISION NOTICE February 02, 2018 Rev1: ? Applicability has been updated to include 2018 model year Sienna vehicles. ? The entire bulletin has been updated. Any previous printed versions of this bulletin should be discarded. When completing a transaxle assembly replacement, Engine Control Module (ECM) (SAE term: Powertrain Control Module [PCM]) replacement, or ECM (PCM) reprogram, ensure the correct ECM (PCM) software is matched with the transaxle assembly hardware. Some 2017 ? 2018 model year Highlander and Sienna vehicles require different ECM (PCM) software based on the transaxle assembly hardware installed in the vehicle. NOTICE Mismatched transaxle assembly hardware and ECM (PCM) software combinations may result in a harsh shift or shift flare. If this occurs after the original repair, additional ECM (PCM) replacement and reprogramming will be required. This additional ECM (PCM) replacement and/or reprogramming is NOT covered under warranty. Use the information in this Service Bulletin to confirm that the correct ECM (PCM) hardware and software are used based on the transaxle assembly part number and serial number. |

Toyota vehicles are equipped with either conventional or run-flat tires. Sometimes punctures may occur as a result of contact with road debris or other hazards. If a puncture occurs, it may be possible to repair the tire and return it to service. With a conventional tire it is not possible to drive for an extended amount of time with the tire at low pressures as damage to the tire may occur. With run-flat tires, due to reinforced sidewalls, it is possible to drive for up to 100 miles at speeds less than 55 mph with little or no damage to the tire. The U.S. Tire Manufacturers Association (UTSMA) provides guidelines and recommendations for tire repair and replacement. It also provides information related to: ? Basic tire information ? Tire maintenance and safety ? Driver education, tire safety curriculum. |
