When the initial attempt to perform an ECU Flash fails, the following steps should resolve the issue:
- Read all available service documentation (SBs, RRTs, Recalls) from the wiTECH Diagnostic Application to ensure that the flash applies to the connected vehicle.
- This step should actually be done before making any flash attempts. If this was not done, the documentation should be reviewed after an initial flash attempt has failed.
- Click the View Service Info button next to the flash file name. The available service documentation will be displayed in a new table that appears below.
- Ensure that your wiTECH Diagnostic Application and scan tool (wiTECH VCI Pod or StarMOBILE) operating systems are up to date.
- View the latest Release Notes (http://kb.dcctools.com/index.php?CategoryID=24) page to determine the latest versions available.
- If your wiTECH Diagnostic Application or scan tool operating system are out of date, update them to the latest version(s) and attempt the ECU flash again.
- Review all available KB articles that may be related to the particular flash failure you are experiencing. We make every attempt to document known flash issues that the field may be experiencing.
- Ensure that the PC running the wiTECH Diagnostic Application is connected to the wiTECH Access Gateway’s wireless or wired network. Ensuring your PC is connected to the wiTECH wireless network will help minimize your risk of being disconnected during a flash session.
- Try using a wired network connection to eliminate any potential wireless networking issues. Examples of wired network connections for PCs and scan tools are explained below:
- Use an Ethernet cable to connect your PC directly to the wiTECH Access Gateway utilizing one of the wiTECH Access Gateway Ethernet ports (1 through 4). These ports are clearly labeled on the wiTECH Access Gateway.
- Use an Ethernet cable to connect either your wiTECH VCI Pod or StarMOBILE device to the wiTECH Access Gateway by utilizing another wiTECH Access Gateway Ethernet port (1 thru 4). Make sure you change the network settings on the scan tool so that the wired network connection is being used.
- Restart the wiTECH Diagnostic Application, choose the appropriate device from the Connection Wizard, and attempt the flash again.
