Posted 27 Aug 2010 Is it flashing or on? If it's on you have a Watchdog error. If it's flashing you have to read out the error code via the programming software. Share this post Link to post Share on other sites
Posted 31 Aug 2010 Get online with the software and read the error code. The light simply shows there is an error, the error code will explain it. Share this post Link to post Share on other sites
