2.21. Controller update

To update the controller, connect it to the diagnostic software and turn the engine off. Select

“Tools” -“Devices update” from the main menu. All available devices are automatically found. The

“Devices update” window will pop up. The “Devices Parameters” window shows the information on current controller firmware version. The “Available updates” window includes a list of updates available for the connected controller. Loading an update not included in the program directory requires clicking “Read update” and selecting the update file. Loaded update should be included in the list of available updates. Click “Update” once the update file has been selected from the list.

When the progress bar reaches 100%, the controller will disconnect and then re-connect. The new version number should appear at the bottom of the screen and should reflect the version number of the update file.

Should the update go wrong the update window will be opened automatically upon connecting with the controller. Perform the update procedure again.
