This bulletin details the Techstream ECU flash reprogramming process and outlines the 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 Lexus 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 \(ECM\) ?
