## NHTSA's summary

TSB: 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 TIS and the Calibration Update Wizard \(CUW\). To ensure the correct ECU software is installed, ECUs will require a Security Signature before the ECU will initialize the flash reprogramming sequence. This bulletin also details the process for acquiring a Security Signature from TIS during the Techstream ECU flash reprogramming process.
