I have just replaced a front impact sensor on a 2010 Mitsubishi lancer. When I plug my Mac scanner (ET129) but Mitsubishi only goes 2009. I have the most recent update for it as well. I'm just wondering if this is the only update available for it, and why doesn't it go to 2010 or even 2014?
Try 2009, it should be able to read srs. If not, then try different scanner. Now, Snap-ON you must buy the software every new update which lets you cover that year. So if your up to software 13.4, it only goes to 2012/2013. So make sure this isn't the same with your machine. Try another car and see if it reads cars above 2009/2010.
