# Service bulletin L\-SB\-0007\-21 Rev2

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.

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 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 \(ECM\) ? Transmission Control Module \(TCM\) ? Any other Lexus\-specific control unit
