INTRODUCTION

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 Global Techstream+ (GTS+) ECU flash reprogramming procedures 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 information.

GTS+ PREPARATION

PROCESS OVERVIEW

1. Verify the vehicle's applicability for recalibration and locate the desired calibration file by performing the GTS+ Health Check function.
   NOTE:

   • GTS+ will automatically search TIS for the appropriate Service Bulletin using the current calibration ID from the vehicle if the PC is connected to the network (see figures below).
   • Calibration file links can be found embedded in the corresponding Service Bulletin.
2. Connect the DCA-8000 battery diagnostic tool using "Power Supply Mode" ONLY.

   The DCA-8000 battery diagnostic tool includes a power supply mode to help maintain battery voltage at 13.5V during ECU reprogramming.

   NOTE:

   • ECU damage may occur if the correct battery charger mode setting is NOT used.
   • Refer to Vehicle Reprogramming Tips for other approved chargers, located at TIS - Diagnostics - Reprogramming - Reference Documents. 
   • The battery diagnostic tool MUST be used in Power Supply Mode to maintain battery voltage at 13.5V while flash reprogramming the vehicle.
   • For details on how to use the battery diagnostic tool, refer to the DCA-8000 Instruction Manual  located at TIS - Diagnostics - Tools & Equipment - Battery Diagnostics. 
3. Locate the appropriate calibration ID and reprogram the vehicle ECU with GTS+.

   GTS+ uses the CUW+ application to open calibration files and facilitate the ECU flash reprogramming process.

4. Attach the Authorized Modifications Label.

   Modifications to ECU calibrations MUST be recorded and properly displayed on the vehicle using the Authorized Modifications Label.
