Ensure that when you're done with reading codes etc, you use the back/return button to exit out of the menus all the way back to the startup menu. Disconnecting the scanner while still communicating with a module can and does have disastrous consequences. I also don't start the engine once I've started reading diagnostics. If you want to read live data, then start the engine first then connect the scanner. Remembering to exit the menus before stopping the engine too.Just ordered one of these so I'll give it a whirl tomorrow. The good thing about Amazon is their returns, so it'll go straight back if it doesn't work.
