| 10134472 | SB: Flash reprogramming allows the 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 informat |
| 10133952 | Some 2011 ? 2012 model year Scion tC vehicles may exhibit excessive wind noise with the moon roof in the ?Full Open? position. This condition typically starts at 45 mph and increases with speed. New Sliding Roof Guide Rail Sub-Assemblies have been developed to improve this condition. |
| 10133921 | Scion vehicles are equipped with SRS, including various airbags and in some models, seat belt pre-tensioners, to help reduce the risk of injury in a collision. If a customer expresses any concerns that the SRS airbags or pretensioner devices did not perform as expected, please follow the steps in the recommendations section below. |
| 10133920 | Some 2011-2013 Scion tCs may exhibit the following conditions; speedometer inoperative or speedometer needle caught/stuck, while all other meter functions work normally. |
